What to Know About Cellphone Radiation — ProPublica

ProPublica recently examined how the federal government, based on quarter-century-old standards, denies that cellphones pose any risks. This guide answers some of the most common questions people ask about cellphone radiation...

The EPA’s Bold New Idea Has Massive Implications for Public Health - Mother Jones

For years, the Environmental Protection Agency's regulation of radiation, carcinogens, and other toxic chemicals has been based on the cautious scientific reasoning that considers even slight exposure to toxins potentially risky to public health. From that premise, the EPA has assessed a wide range of pollution, including lung-clogging particulate matter, Superfund cleanup, water treatment, radiation exposure, and risk assessments...

North Korea nuclear test site has collapsed and may be out of action – China study | World news | The Guardian

North Korea’s main nuclear test site has partially collapsed under the stress of multiple explosions, possibly rendering it unsafe for further testing and leaving it vulnerable to radiation leaks, a study by Chinese geologists has shown.....North Korea nuclear test site has collapsed and may be out of action – China study | World news | The Guardian

Hot mess: states struggle to deal with radioactive fracking waste

The Marcellus Shale has transformed the Appalachian Basin into an energy juggernaut. Even amid a recent drilling slowdown, regional daily production averages enough natural gas to power more than 200,000 U.S. homes for a year.

 But the rise of hydraulic fracturing over the past decade has created another boom: tons of radioactive materials experts call an “orphan” waste stream. No federal agency fully regulates oil and gas drilling byproducts — which include brine, sludge, rock and soiled equipment — leaving tracking and handling to states that may be reluctant to alienate energy interests.

“Nobody can say how much of any type of waste is being produced, what it is, and where it’s ending up,” said Nadia Steinzor of the environmental group Earthworks, who co-wrote a report on shale waste. (Earthworks has received funding from The Heinz Endowments, as has the Center for Public Integrity)....

Major Cell Phone Radiation Study Reignites Cancer Questions

Federal scientists released partial findings Friday from a $25-million animal study that tested the possibility of links between cancer and chronic exposure to the type of radiation emitted from cell phones and wireless devices. The findings, which chronicle an unprecedented number of rodents subjected to a lifetime of electromagnetic radiation starting in utero, present some of the strongest evidence to date that such exposure is associated with the formation of rare cancers in at least two cell types in the brains and hearts of rats. The results, which were posted on a prepublication Web site run by Cold Spring Harbor Laboratory, are poised to reignite controversy about how such everyday exposure might affect human health.

Researchers at the National Toxicology Program (NTP), a federal interagency group under the National Institutes of Health, led the study. They chronically exposed rodents to carefully calibrated radio-frequency (RF) radiation levels designed to roughly emulate what humans with heavy cell phone use or exposure could theoretically experience in their daily lives. The animals were placed in specially built chambers that dosed their whole bodies with varying amounts and types of this radiation for approximately nine hours per day throughout their two-year life spans. “This is by far—far and away—the most carefully done cell phone bioassay, a biological assessment. This is a classic study that is done for trying to understand cancers in humans,” says Christopher Portier, a retired head of the NTP who helped launch the study and still sometimes works for the federal government as a consultant scientist. “There will have to be a lot of work after this to assess if it causes problems in humans, but the fact that you can do it in rats will be a big issue. It actually has me concerned, and I’m an expert.”...
