A massive US study found that living near nuclear power plants is linked to higher cancer death rates. The study looked at data from 2000-2018 and adjusted for many factors.

Researchers at Harvard T.H. Chan School of Public Health studied the relationship between nuclear power plants and cancer mortality across the United States. They found that counties closer to operating nuclear power plants have higher cancer death rates than those farther away. This is the first study of its kind in the 21st century. The results do not prove that nuclear plants cause cancer deaths, but they suggest a need for further investigation into the possible health effects of nuclear power.

The researchers analyzed national data from 2000-2018 using a method called 'continuous proximity.' This approach measures how close each county is to nuclear power plants and accounts for the combined influence of multiple nearby facilities. They also adjusted for many factors that could affect cancer death rates, including educational attainment, median household income, racial composition, average temperature, relative humidity, smoking prevalence, BMI, and distance to the nearest hospital.

The study found that even after adjusting for these factors, counties closer to nuclear power plants experienced higher cancer mortality rates. The researchers estimate that approximately 115,000 cancer deaths nationwide were associated with proximity to nuclear power plants over the study period.

The link was strongest among older adults. 'Our study suggests that living near a nuclear power plant may carry a measurable cancer risk -- one that lessens with distance,' said senior author Petros Koutrakis. 'We recommend that more studies be done that address the issue of NPPs and health impacts, particularly at a time when nuclear power is being promoted as a clean solution to climate change.'

Why It Matters

This study matters because it highlights the need for further research into the potential health effects of nuclear power. As India explores its own nuclear energy options, this study serves as a reminder to consider the potential risks and benefits.
