The EPA has left harmful regulations in place for decades, which caused 1600 unnecessary deaths at Fukushima, and countless more by helping suppress the most effective source of clean energy. While renewables may capture the limelight, the leading source of new energy worldwide is coal, and it is growing far faster.
Present radiation regulations are based on bad science. The linear no threshold hypothesis is provably false today, and counter evidence already existed even at the time of its adoption. Since then, a growing body of evidence and scientific understanding show that low levels of radiation are harmless and potentially beneficial. Aside from providing a basis for fear-mongering, misinformed regulations also prevent promising research into the use of low level radiation for medical applications.
Scientists for Accurate Radiation Information have recently petitioned the EPA for scientific/risk-based radiation regulations. There are also other areas where the EPA adopts the ALARA (as low as reasonably achievable) principle for regulation, which is fundamentally misguided. Such regulation carries an opportunity cost, and the extensive effort to eliminate infinitesimal perceived damage is wasted when it could achieve a much greater positive effect if applied to other more serious risks.
