• Massive US study finds higher cancer death rates near nuclear power plants A new nationwide study led by researchers at the Harvard T.H. • Chan School of Public Health reports that U.S. • counties situated closer to operating nuclear power plants (NPPs) have higher cancer death rates than counties located farther away. • This is the first study of the 21st century to examine the relationship between proximity to NPPs and cancer mortality across every nuclear power plant and all U.S. • The authors caution that the results do not prove that nuclear plants cause cancer deaths. • However, they say the findings point to the need for deeper investigation into the possible health effects of nuclear power.

Article Summaries:

  • A nationwide analysis published in Nature Communications found that U.S. counties closer to operating nuclear power plants (NPPs) have higher cancer mortality rates than those farther away. Researchers from Harvard T.H. Chan School of Public Health examined data from every U.S. nuclear facility and all counties between 2000‑2018, adjusting for income, education, smoking, obesity, environmental conditions, and health‑care access. Even after these controls, cancer deaths were elevated near NPPs, especially among older adults. The team estimates roughly 115,000 cancer deaths nationwide (≈6,400 per year) could be linked to proximity to nuclear plants, calling for further investigation into potential health effects.

Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 and 2018, adjusting for income, education, smoking, obesity, environmental conditions, and access to health care. Even after accounting for those factors, cancer mortality was hig
