When Chernobyl accident happend in 1986, Belarus failed evacuating people and didn’t distribute potassium iodide preparation either just like Japan after Fukushima accident.
According to Belarus Minsk medical university, from 1986 to 2004, thyroid cancer rate increased in following 18 years.
Especially the cancer rate of people who are over 46 years old increased steadily.
This statistics shows even if you were older than 28 years old when Chernobyl happened, the more time passes, the more likely you are to have thyroid cancer.
