Researchers find elevated radiation near U.S. fracking sites

(Reuters) – Radiation levels downwind of U.S. hydraulic fracturing drilling sites tend to be significantly higher than background levels, posing a potential health risk to nearby residents, according to a study by Harvard researchers released on Tuesday.

The study, published in the journal Nature, adds to controversy over the drilling method known as fracking, which has helped the United States become the world’s biggest oil and gas producer over the past decade but which environmentalists say threatens water and air.

President Donald Trump supports fracking because of its economic benefits, and his Democratic rival Joe Biden has promised to continue to allow it if elected even though he aims to impose an ambitious plan to fight climate change.

Areas within 20 kilometers (12 miles) downwind of 100 fracking wells tend to have radiation levels that are about 7% above normal background levels, according to the study, which examined thousands of the U.S. Environmental Protection Agency’s radiation monitor readings nationwide from 2011 to 2017.

The study showed readings can go much higher in areas closer to drill sites, or in areas with higher concentrations of drill sites.

“The increases are not extremely dangerous, but could raise certain health risks to people living nearby,” said the study’s lead author, Petros Koutrakis.

Radioactive particles can be inhaled and increase the risk of lung cancer.

Koutrakis said the source of the radiation is likely naturally-occurring radioactive material brought up to the surface in drilling waste fluids during fracking, a process that pumps water underground to break up shale formations.

The study found the biggest increases in radiation levels near drill sites in states like Pennsylvania and Ohio that have higher concentrations of naturally occurring radioactive material beneath the surface, and lower readings in places like Texas and New Mexico that have less.

It also found less pronounced increases in particle radiation levels near conventional drilling operations.

Koutrakis said further study was needed to determine whether the radiation was being released during the drilling process, or from wastewater storage nearby.

“Our hope is that once we understand the source more clearly, there will be engineering methods to control this,” he said.

Lung radiation shows promise for COVID-19 pneumonia; smoking raises risks

By Nancy Lapid

(Reuters) – The following is a brief roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

Lung radiation may hasten COVID-19 pneumonia recovery

A low dose of radiation to the lungs of COVID-19 pneumonia patients can help them recover more quickly, a small study suggests. Doctors at Emory University in Atlanta treated 10 such patients with lung radiation and compared them to 10 patients of similar ages who received usual care, without radiation. With radiation, the average time to significant improvement was three days, compared to 12 days in the control group.

Other potential effects included a shorter average time to hospital discharge (12 days with radiation versus 20 days without it) and a lower risk of mechanical ventilation (10% with radiation versus 40% without it). But those two differences were too small to rule out the possibility they were due to chance, the researchers found.

The radiation group was “a little older, a little sicker, and their lungs were a little more damaged … but despite that we saw a strong signal of efficacy,” Emory’s Dr. Mohammad Khan told Reuters.

Khan noted that in the radiation group, COVID-19 medications were withheld before and after the treatment, so the results reflect the effect of the radiation alone.

“Radiotherapy,” Khan said, “can reduce the inflammation in the lungs of COVID-19 patients and reduce the cytokines that are causing the inflammation.” Cytokines are proteins made by the immune system. The results on the first five patients have been accepted for publication by the journal Cancer.

The results on all 10 were posted on Tuesday ahead of peer review on the website medRxiv. The researchers have launched a randomized controlled trial of the treatment and expect to eventually include multiple centers.

Smoking may boost severe COVID-19 risk among young adults

Close to one third of young U.S. adults appear to have an elevated risk for severe COVID-19, with smoking their strongest risk factor, according to survey data.

Researchers looked at data from more than 8,000 participants, ages 18 to 25, in the nationally representative National Health Interview Survey for 2016 to 2018. They also looked at participants’ medical conditions identified by the U.S. Centers for Disease Control and Prevention as making people of any age “medically vulnerable” to severe illness from the coronavirus.

Among these are diabetes, heart disease, immune problems, smoking, poorly controlled HIV or AIDS, and respiratory diseases. Overall, 32% of the young adults surveyed were seen as medically vulnerable to severe COVID-19. Among non-smoking young adults, however, only 16% were seen as medically vulnerable.

“Efforts to reduce smoking and e-cigarette use among young adults would likely reduce their medical vulnerability to severe illness,” the researchers said on Monday in the study published in the Journal of Adolescent Health. “Our analysis suggests that risk from smoking and e-cigarette use is highest among young adults who are male, white, and lower income and who are fully or partially uninsured.”

Coronavirus may rarely pass through placenta

It is unclear whether the coronavirus can pass through the womb from mother to fetus.

On Tuesday, doctors in France reported a very rare case that suggests transmission through the placenta may be possible. In the journal Nature Communications, they described a baby born prematurely to a mother with COVID-19. They found the virus in placental tissue as well as in the mother’s and baby’s blood, which suggests that trans-placental transmission of the novel coronavirus virus may be possible, although further studies are needed. Both mother and baby recovered well.

Marian Knight, a professor of maternal and child population health at Oxford University, said the case should not be a major worry for pregnant women. Among the many thousands of babies born to mothers infected with the virus, only around 1% to 2% have been reported to also have had a positive test, Knight said.

Promising results from early trial of new vaccine

Moderna Inc’s experimental vaccine for COVID-19, mRNA-1273, was safe and provoked immune responses in all 45 healthy volunteers in a first-in-humans phase 1 study, researchers reported on Tuesday in the New England Journal of Medicine. Volunteers who got two doses of the vaccine had levels of virus-killing antibodies that exceeded the average levels seen in recovered COVID-19 patients.

Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, whose researchers developed Moderna’s vaccine candidate, called the results good news. Fauci noted that the study found no serious adverse events and the vaccine produced “reasonably high” levels of virus-killing or neutralizing antibodies.

“If your vaccine can induce a response comparable with natural infection, that’s a winner,” Fauci told Reuters. “That’s why we’re very pleased by the results.” A phase 2 trial testing the vaccine’s efficacy in a larger group started in May.

A much larger phase 3 trial to confirm efficacy and identify rare side effects will begin this month, ultimately including 30,000 participants. Separately, early-stage human trial data on a vaccine being developed by AstraZeneca and Oxford University will be published on July 20, the Lancet medical journal said on Wednesday.

Russia rocket accident likely had two explosions, Norway monitor says

OSLO (Reuters) – An explosion that killed five Russian scientists during a rocket engine test this month was followed by a second blast two hours later, the likely source of a spike in radiation, Norway’s nuclear test-ban monitor said on Friday.

The second explosion was likely from an airborne rocket powered by radioactive fuel, the Norsar agency said – though the governor of Russia’s Arkhangelsk region, where the blast took place, dismissed reports of another blast.

“The aftermath of the incident does not carry any threat,” the governor, Igor Orlov, told the Interfax news agency. “Everything else is yet another round of disinformation.”

Russia’s Ministry of Defence did not immediately respond to a request for comment when contacted by Reuters on Friday.

There has been contradictory information about the Aug. 8 accident near the White Sea in far northern Russia and its consequences.

Russia’s Defence Ministry initially said background radiation remained normal, while the state weather agency said radiation levels had risen.

Russia’s state nuclear agency, Rosatom, said on Aug. 10 the accident involved “isotope power sources” but did not give further details.

Rosatom has acknowledged that five of its workers were killed. Two military personnel were also reported to have been killed.

Norway’s DSA nuclear safety authority said on Aug. 15 it had found tiny amounts of radioactive iodine near Norway’s Arctic border with Russia, although it could not say whether it was linked to the Russian accident.

Norsar’s detection of a second blast was first reported by Norwegian newspaper Aftenposten on Friday.

“We registered two explosions, of which the last one coincided in time with the reported increase in radiation,” Norsar Chief Executive Anne Stroemmen Lycke told Reuters. She added that this likely came from the rocket’s fuel.

The second explosion was detected only by infrasonic air pressure sensors and not by the seismic monitors that pick up movements in the ground, she added.

Global network’s nuclear sensors in Russia went offline after mystery blast

By Francois Murphy

VIENNA (Reuters) – The operator of a global network of radioactivity sensors said on Monday its two Russian sites closest to a mysterious explosion on Aug. 8 went offline two days after the blast, raising concern about possible tampering by Russia.

The Russian Defense Ministry, which operates the two stations, did not immediately reply to a request for comment.

Russia’s state nuclear agency Rosatom has acknowledged that nuclear workers were killed in the explosion, which occurred during a rocket engine test near the White Sea in far northern Russia.

The explosion also caused a spike in radiation in a nearby city and prompted a local run on iodine, which is used to reduce the effects of radiation exposure.

Russian authorities have given no official explanation for why the blast triggered the rise in radiation. U.S.-based nuclear experts have said they suspect Russia was testing a nuclear-powered cruise missile vaunted by President Vladimir Putin last year.

“We’re … addressing w/ station operators technical problems experienced at two neighboring stations,” Lassina Zerbo, head of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), said on Twitter overnight.

The CTBTO’s International Monitoring System includes atmospheric sensors that pick up so-called radionuclide particles wafting through the air. Zerbo said data from stations on or near the path of a potential plume of gas from the explosion were still being analyzed.

“COMMUNICATION AND NETWORK ISSUES”

The two Russian monitoring stations nearest the explosion, Dubna and Kirov, stopped transmitting on Aug. 10, and Russian officials told the CTBTO they were having “communication and network issues”, a CTBTO spokeswoman said on Monday.

“We’re awaiting further reports on when the stations and/or the communication system will be restored to full functionality.”

While the CTBTO’s IMS network is global and its stations report data back to CTBTO headquarters in Vienna, those stations are operated by the countries in which they are located.

It is not clear what caused the outage or whether the stations might have been tampered with by Russia, analysts said.

“About 48 hours after the incident in Russia on Aug. 8 these stations stopped transmitting data. I find that to be a curious coincidence,” Daryl Kimball, executive director of the Arms Control Association, a Washington-based think tank.

He and other analysts said any Russian tampering with IMS stations would be a serious matter but it was also likely to be futile as other IMS or national stations could also pick up telltale particles.

“There is no point in what Russia seems to have tried to do. The network of international sensors is too dense for one country withholding data to hide an event,” said Jeffrey Lewis, director of the East Asia Non-Proliferation Program at the Middlebury Institute in California.

The CTBTO’s Zerbo also posted a simulation of the explosion’s possible plume, showing it reaching Dubna and Kirov on Aug. 10 and Aug. 11, two and three days after the explosion.

Rosatom has said the accident, which killed five of its staff, involved “isotope power sources”.

The CTBTO’s IMS comprises more than 300 seismic, hydroacoustic, infrasound and radionuclide stations dotted around the world that together are aimed at detecting and locating a nuclear test anywhere. Its technology can, however, be put to other uses, as in the Russian case.

OSLO (Reuters) – A Soviet nuclear submarine which sank off Norway in 1989 is still emitting radiation, researchers said on Wednesday following an expedition that used a remotely controlled vehicle for the first time.

The wreck of the Komsomolets lies on the bottom of the Norwegian Sea at a depth of about 1,700 meters (5,577 feet).

Authorities have conducted yearly expeditions to monitor radiation levels since the 1990s but this year’s inspection was the first one to use a remotely operated vehicle called Aegir 6000 to film the wreckage and take samples which will be further analyzed.

The scientific mission’s samples show levels of radioactivity at the site up to 800,000 higher than normal, the Norwegian Radiation and Nuclear Safety Authority said in a statement.

“This is, of course, a higher level than we would usually measure out at sea but the levels we have found now are not alarming,” said expedition leader Hilde Elise Heldal of the Norwegian Institute of Marine Research.

Radioactivity levels “thin out” quickly at these depths and there are few fish in the area, she said.

The Komsomolets sank on April 7, 1989, after a fire broke out onboard, killing 42 crew.

On July 1, 14 Russian sailors were killed aboard a nuclear submarine operating in the Arctic.

As Fukushima residents return, some see hope in nuclear tourism

FUKUSHIMA, Japan (Reuters) – On a cold day in February, Takuto Okamoto guided his first tour group to a sight few outsiders had witnessed in person: the construction cranes looming over Japan’s Fukushima Daiichi nuclear plant.

Seven years after a deadly tsunami ripped through the Tokyo Electric Power plant, Okamoto and other tour organizers are bringing curious sightseers to the region as residents who fled the nuclear catastrophe trickle back.

Many returnees hope tourism will help resuscitate their towns and ease radiation fears.

But some worry about drawing a line under a disaster whose impact will be felt far into the future. The cleanup, including the removal of melted uranium fuel, may take four decades and cost several billion U.S. dollars a year.

“The disaster happened and the issue now is how people rebuild their lives,” Okamoto said after his group stopped in Tomioka, 10 kilometers (6.21 miles) south of the nuclear plant. He wants to bring groups twice a week, compared with only twice a month now.

Electronic signs on the highway to Tomioka showed radiation around 100 times normal background levels, as Okamoto’s passengers peered out tour bus windows at the cranes poking above Fukushima Daiichi.

“For me, it’s more for bragging rights, to be perfectly honest,” said Louie Ching, 33, a Filipino programmer. Ching, two other Filipinos and a Japanese man who visited Chernobyl last year each paid 23,000 yen ($208.75) for a day trip from Tokyo.

NAMIE

The group had earlier wandered around Namie, a town 4 kilometers north of the plant to which residents began returning last year after authorities lifted restrictions. So far, only about 700 of 21,000 people are back – a ratio similar to that of other ghost towns near the nuclear site.

Former residents Mitsuru Watanabe, 80, and his wife Rumeko, 79, have no plans to return. They were only in town to clear out their shuttered restaurant before it is demolished, and they chatted with tourists while they worked.

“We used to pull in around 100 million yen a year,” Mitsuru said as he invited the tourists inside. A 2011 calendar hung on the wall, and unfilled orders from the evacuation day remained on a whiteboard in the kitchen.

“We want people to come. They can go home and tell other people about us,” Mitsuru said among the dusty tables.

Okamoto’s group later visited the nearby coastline, where the tsunami killed hundreds of people. Abandoned rice paddies, a few derelict houses that withstood the wave and the gutted Ukedo elementary school are all that remain.

It’s here, behind a new sea wall at the edge of the restricted radiation zone, that Fukushima Prefecture plans to build a memorial park and 5,200-square-metre (56,000-square-foot) archive center with video displays and exhibits about the quake, tsunami and nuclear calamity.

LURING TOURISTS

“It will be a starting point for visitors,” Kazuhiro Ono, the prefecture’s deputy director for tourism, said of the center. The Japan Tourism Agency will fund the project, Ono added.

Ono wants tourists to come to Fukushima, particularly foreigners, who have so far steered clear. Overseas visitors spent more than 70 million days in Japan last year, triple the number in 2011. About 94,000 of those were in Fukushima.

Tokyo Electric will provide material for the archive, although the final budget for the project has yet to be finalised, he said.

“Some people have suggested a barbecue area or a promenade,” said Hidezo Sato, a former seed merchant in Namie who leads a residents’ group. A “1” sticker on the radiation meter around his neck identified him as being the first to return to the town.

“If people come to brag about getting close to the plant, that can’t be helped, but at least they’ll come,” Sato said. The archive will help ease radiation fears, he added.

SPECTACLE

Standing outside a farmhouse as workmen refurbished it so her family could return, Mayumi Matsumoto, 54, said she was uneasy about the park and archive.

“We haven’t gotten to the bottom of what happened at the plant, and now is not the time,” she said.

Matsumoto had come back for a day to host a rice-planting event for about 40 university students. Later they toured Namie on two buses, including a stop at scaffolding near the planned memorial park site to view Fukushima Daiichi’s cranes.

Matsumoto described her feelings toward Tokyo Electric as “complicated,” because it is responsible for the disaster but also helped her family cope its aftermath. One of her sons works for the utility and has faced abuse from angry locals, she added.

“It’s good that people want to come to Namie, but not if they just want to get close to the nuclear plant. I don’t want it to become a spectacle,” Matsumoto said.

Okamoto is not the only guide offering tours in the area, although visits of any kind remain rare. He said he hoped his clients would come away with more than a few photographs.

“If people can see for themselves the damage caused by tsunami and nuclear plant, they will understand that we need to stop it from happening again,” said Okamoto, who attended university in a neighboring prefecture. “So far, we haven’t come across any opposition from the local people.”

Japan’s Tepco gets slapped with new U.S. lawsuit over Fukushima

TOKYO (Reuters) – Tokyo Electric Power Co Holdings said on Thursday it has been hit with another lawsuit filed in a U.S. court seeking $5 billion for compensation over the 2011 Fukushima nuclear disaster, the second filed against the utility in a U.S. court.

The suit filed by 157 individuals is seeking that amount to set up a compensation fund for the costs of medical tests and treatment they say they need after efforts to support the recovery from the world’s worst nuclear disaster since Chernobyl in 1986.

The utility, known as Tepco, is being sued regarding improper design, construction and maintenance, claiming compensation for physical, mental and economic damages, the company said in a statement.

A multi-plaintiff lawsuit was filed on Aug. 18, 2017, against Tokyo Electric Power Co and other parties in the Southern District Court in California, the legal information group Justia said on its website.

Tepco has been hit with more lawsuits than in any previous Japanese contamination suit over the meltdowns of three reactors at its Fukushima Daiichi plant north of Tokyo after a massive earthquake and tsunami in March 2011.

Radiation forced 160,000 people from their homes, many never to return, and destroyed businesses, fisheries and agriculture.

In June, a federal appeals court cleared the way for a group of U.S. military personnel to file a suit against Tepco over radiation exposure that they say occurred during recovery efforts on board the USS Ronald Reagan.

Tepco did not make clear whether the two suits involved the same plaintiffs but Justia has two cases listed.

Shareholders of Tepco are suing the utility’s executives for a record 5.5 trillion yen ($67.4 billion) in compensation, in a long standing case.

The company’s former chairman and other executives of the company appeared in court in June to answer charges of professional negligence, in the first criminal case after the meltdowns at the plant. They all pleaded not guilty.

The criminal and civil legal cases do not threaten financial ruin for Tepco, which is backstopped by Japanese taxpayers. The company faces nearly $150 million of costs to decommission the Fukushima plant and clean up the surrounding area, according to the latest government estimate.

Tepco shares fell nearly 1 percent on Thursday, in line with many of Japan’s other utilities, before the company announced the lawsuit.

Hanford nuclear site accident puts focus on aging U.S. facilities

By Tom James

SEATTLE (Reuters) – The collapse of a tunnel used to store radioactive waste at one of the most contaminated U.S. nuclear sites has raised concerns among watchdog groups and others who study the country’s nuclear facilities because many are aging and fraught with problems.

“They’re fighting a losing battle to keep these plants from falling apart,” said Robert Alvarez, a former policy adviser at the U.S. Department of Energy who was charged with making an inventory of nuclear sites under President Bill Clinton.

“The longer you wait to deal with this problem, the more dangerous it becomes,” said Alvarez, a senior scholar at the Institute for Policy Studies, where he focuses on nuclear energy and disarmament.

The Energy Department did not respond to requests for comment.

No radiation was released during Tuesday’s incident at a plutonium-handling facility in the Hanford Nuclear Reservation in Washington state, but thousands of workers were ordered to take cover and some were evacuated as a precaution.

The state of facilities in the U.S. nuclear network has been detailed by the Department of Energy, Government Accountability Office and Defense Nuclear Facilities Safety Board. They have noted eroding walls, leaking roofs, and risks of electrical fires and groundwater contamination.

In 2016, Frank Klotz, head of the National Nuclear Security Administration, an Energy Department agency overseeing maintenance of nuclear warheads, warned Congress about risks posed by aging facilities.

Decontaminating and demolishing the Energy Department’s shuttered facilities will cost $32 billion, it said in a 2016 report. It also noted a $6 billion maintenance backlog.

In the 1940s the U.S. government built Hanford and other complexes to produce plutonium and uranium for atomic bombs under the Manhattan Project.

“That was an era when the defense mission took priority over everything else,” said Edwin Lyman, a senior scientist at the Union of Concerned Scientists. “We’re dealing with the legacy of that.”

RISKS DOCUMENTED

Many of those sites are now vacant but contaminated.

A 2009 Energy Department survey found nearly 300 shuttered, contaminated and deteriorating sites. Six years later it found that fewer than 60 had been cleaned up.

A 2015 Energy Department audit said delays in cleaning contaminated facilities “expose the Department, its employees and the public to ever-increasing levels of risk.”

Risks identified at the sites included leaking roofs carrying radioactivity into groundwater, roof collapses and electrical fires that could release radioactive particles.

A 2014 Energy Department audit noted a high risk of fire and groundwater contamination at the shuttered Heavy Element Facility at Lawrence Livermore National Laboratory, which is surrounded by homes and businesses near California’s Bay Area.

Problems have also been identified at active facilities including the Savannah River Site, a nuclear reservation in South Carolina. A 2015 report by the Defense Nuclear Facilities Safety Board found “severe” erosion in concrete walls of an exhaust tunnel used to prevent release of radioactive air.

A 2016 Energy Department audit of one of the United States’ main uranium handling facilities, the Y-12 National Security Complex in Oak Ridge, Tennessee, warned that “intense precipitation or snow” could collapse parts its roof, possibly causing an accident involving radioactivity.

“It sounds crazy, but it’s true,” said Don Hancock, who has studied the Tennessee facility in his work at the Southwest Information and Research Center, an Albuquerque nonprofit that monitors nuclear sites.

In Hanford’s case, risk of a tunnel collapse was known in 2015, when the Energy Department noted wooden beams in one tunnel had lost 40 percent of their strength and were being weakened by gamma radiation.

Energy Department spokesman Mark Heeter in nearby Richland said in an email that the agency saw Tuesday’s prompt discovery of the collapse as a success.

“The maintenance and improvement of aging infrastructure across the Hanford site … remains a top priority,” he said.

Nationwide, part of the risk comes from having to maintain and safeguard so many sites with different types of nuclear waste, said Frank Wolak, head of Stanford University’s Program on Energy and Sustainable Development.

“You’re asking for trouble with the fact that you’ve got it spread all over the country,” he said. “The right answer is to consolidate the stuff that is highly contaminated, and apply the best technology to it.”
