The radiation exposure from consuming a banana is approximately 1 % of the average daily exposure to radiation , which is 100 banana equivalent doses ( BED ) . The maximum permitted radiation leakage for a nuclear power plant is equivalent to 2,500 BED ( 250 μSv ) per year , while a chest CT scan delivers 70,000 BED ( 7 mSv ) . A lethal dose of radiation is approximately 35,000,000 BED ( 3500 mSv ) . A person living from the Three Mile Island nuclear reactor received an average of 800 BED of exposure to radiation during the 1979 Three Mile Island accident
