The agency concluded that any additional cancer risk from radiation was small—extremely small, for the most part—and chiefly limited to those living closest to the plant.
The WHO found:
- For leukemia, a lifetime risk increase of around 7% over baseline cancer rates for males exposed to the radiation as infants, and about 6% for females exposed as babies.
- For all solid cancers (meaning everything with a discrete tumor mass, including brain and breast cancer), a lifetime risk increase of about 4% over baseline rates for females exposed as infants.
- For thyroid cancer (which chiefly occurs in women) a lifetime risk increase of around 70% over baseline rates for women exposed as infants.
