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.
