Hydraulic fracturing has been a crowing topic of the upcoming presidential election . Biden hasrefusedto ban it , Trump has said he’llexpandit staggeringly . Well , a Modern Harvard study suggest that the drilling practice session is even more grievous than we antecedently thought .
The new research , release inNature Communicationson Tuesday , shows that radiation levels up to 12 international nautical mile ( 20 kilometers ) windward of boring sites can be dangerously high . The Harvard scientists hold data from 157 Cold War - era federal radiation monitoring stations across the U.S. between 2001 and 2017 . They then compare those numbers with data on the position and yield records of 120,000 fracking wells to examine the step-up in the radioactivity levels of airborne particles in locations that had wells upwind .
The research worker found that land site that had 100 fracking wells within 12 mile upwind , tended to have radiation levels about 7 % above normal background levels . That alone “ may cause adverse health outcomes in nearby communities , ” the work says , but as the researcher note , some post in the Northeast are 12 miles downwind of over 500 fracking site . The gamy radioactivity point they keep were near the Marcellus and Utica shale field in Pennsylvania and Ohio , where air subatomic particle radioactivity was 40 % higher than normal background levels .

This level of radioactivity near fracking cognitive operation was eminent than levels measured in areas near conventional drilling functioning . Texas and New Mexico , for illustration , read lower readings than places near the fracking mathematical process near the Northeast shale fields . That ’s because established crude oil and accelerator pedal drilling does n’t disturb hole-and-corner rocks very much , rocks that contain a uranium isotope that ’s the source of their radiation . Fracking , on the other deal , take blasting through shale and other careen formations , which releases the U . That uranium then breaks into atom , which then become committed to particles in the zephyr and get carried windward .
The study ’s lead author , Petros Koutrakis , told Reutersthat the levels of radiation his team observed “ are not extremely dangerous , but could rear sure wellness risks to citizenry inhabit nearby . ” The authors note that short - condition exposure to subatomic particle radiation has been connect to adverse health effect like adecrease in lung subroutine , gamy blood pressure , andincreasedinflammationthat can cause cardiovascular issues .
The cogitation add to former inquiry which shows that fracking canturn nearby water radioactive , leakcarcinogenic pollutant into zephyr and waterand can evenmess with testosterone levels . Fracking is also a monolithic source ofplanet - warming glasshouse gas emissions . So even if the airborne radioactivity levels it creates are n’t that unsafe , it seems betternot to take a luck on frackingdespite what each presidential nominee is foretell .
