A University of Toledo study recently connected the proximity of fracking to higher household concentrations of radon gas, the second leading cause of lung cancer in the U.S, according to Science Daily.

Researchers measured and geocoded data from 118,421 homes across all 88 counties in Ohio between 2007 and 2014, finding the closer the distance between a fracking well and a residence, the higher the indoor radon concentration in the home.

The study also found the average radon concentrations among all tested homes across the state are higher than safe levels outlined by U.S. Environmental Protection Agency and World Health Organization standards.
