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 worlds 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.
