UPI - Fukushima radiation has been linked to a surge in thyroid cancer among children near the disaster area,... The rates were about 20 to 50 times the national average, according to the analysis. The findings were based on screenings of 370,000 Fukushima residents age 18 or younger, and the culprit was increased radiation exposure since the Fukushima nuclear disaster hit the area in March 2011. In late August, the prefecture had identified 104 cases of thyroid cancer. Some epidemiologists like Shoichiro Tsugane of the National Cancer Center disputed the findings and said it is too early to say whether the results are conclusive.
