Radioactivity muddles the alphabet of DNA
Curtin University researchers have shown natural radioactivity within DNA can alter chemical compounds, providing a new pathway for genetic mutation. The research, recently published in Biochimica et Biophysica Acta-General Subjects, for the first time looked at natural radioactivity within human DNA on the atomic-scale. While radioactivity occurs naturally in our bodies as well as in every living organism across the planet, it was never before thought to affect our DNA in such a direct way. (2013-12-17)

Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments
More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new Duke study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams. (2018-01-19)

Radioactive contaminants found in coal ash
