In Massachusetts, residential proximity to a nuclear power plant (NPP) was associated with significantly increased cancer incidence, with risk declining by distance, according to a new study led by Harvard T.H. Chan School of Public Health.

The study was published Dec. 17 in Environmental Health. It was conducted by researchers in the Department of Environmental Health, including corresponding author Yazan Alwadi, PhD student, and senior author Petros Koutrakis, professor of environmental sciences.

Despite widespread—and potentially expanding—reliance on nuclear power in the U.S., epidemiologic research investigating the health impacts of NPPs remains limited. Meanwhile, the results of studies conducted internationally vary significantly. To broaden the evidence base, the researchers assessed proximity of Massachusetts zip codes to nuclear power plants and 2000-2018 cancer incidence data collected by the Massachusetts Cancer Registry. They controlled for confounders such as air pollution and sociodemographic factors.

The researchers estimated that about 20,600 cancer cases in the state—roughly 3.3% of all the cases included in the study—were attributable to living near an NPP, with risk declining sharply beyond roughly 30 kilometers from a facility. The risk of developing cancer attributable to living near an NPP generally increased with age.

According to the researchers, the findings highlight the importance of acknowledging and addressing nuclear energy’s health impacts, particularly at a time when its expansion is being promoted as a solution to climate change.

How many people live within 30km from the Hunterston site in North Ayrshire where Scottish Labour want to see a new nuclear power station built? 300-400 000. 3.3% as per the above study – 9 900 avoidable cancers

Sometimes research finding similar evidence in the UK has been discounted by the media simply because it was funded by activist groups. This cannot be considered for these researchers:

Twenty-four faculty members or researchers affiliated with Harvard T.H. Chan School of Public Health were named to Clarivate Analytic’s 2025 list of Highly Cited Researchers. The annual list includes researchers from around the world whose papers have been cited most often by their peers—in the top 1% of citations for a chosen field or fields.
