Effects of the Chernobyl disaster of radiation exposure after the Chernobyl disaster in 1986, but prior to the disaster the number of children affected by thyroid cancer was relatively low globally. Every year about, “0.1–2.2 individuals per million of all aged under 15 years old world wide” were affected by thyroid cancer. Research has shown after the Chernobyl disaster the level of thyroid cancer, particularly in children near the radiation exposure, has abnormally increased. Although iodine-131 has a relatively short half-life compared to other radioactive isotopes, iodine-131 made its way through the food chain through a milk-to-consumer pathway. 95% of iodine-131 was ingested through milk
Effects of the Chernobyl disaster in 1988 to be "600,000 man Sv, equivalent on average to 21 additional days of world exposure to natural background radiation." The inhalation dose (internal dose) for the public during the time of the accident and their evacuation from the area in what is now the 30 km evacuation zone around the plant has been estimated (based on ground deposition of caesium-137) to be between 3 and 150 mSv. Thyroid doses for adults around the Chernobyl area were estimated to be between 20 and 1000 mSv, while for one-year-old infants, these estimates were higher, at 20 to 6000 mSv. For
