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 were evacuated from the area, including 50,000 from the nearby town of Pripyat, Ukraine. Health officials have predicted that over the next 70 years there will be a 28% increase in cancer rates in much of the population which was exposed to the 5–12 EBq (depending on source) of radioactive contamination released from the reactor. Soviet scientists reported that the Chernobyl Unit 4 reactor contained about 180–190 metric tons of uranium dioxide fuel and fission products. Estimates of the amount of this material that escaped range from 5 to 30%. Because of the intense heat of the fire, and with
