This calculator estimates the internal and external radiation dose received by your thyroid gland from radionuclides in fallout from nuclear tests conducted at the Nevada Test Site (NTS) and sites outside of the United States (global fallout). In addition, the calculator estimates your risk of developing thyroid cancer from that exposure. This calculator also provides an estimate of probability of causation (PC), sometimes called assigned share (AS) for individuals who have been diagnosed with thyroid cancer.
To use this calculator, you will need to supply information to help characterize your exposure to radioactive fallout, including:
- your sex assigned at birth and date of birth;
- the states and counties that you lived in between 1951 and 1982;
- An estimate of the primary types and amounts of milk that you consumed at different ages.
Before you start the calculator, please read About the I-131 Calculator to learn more about the tests, fallout exposure, and thyroid cancer risks. For additional information, see Get the Facts about Exposure to I-131 Radiation.
