A-bomb survivor publishes book, warns of radiation damage

HIROSHIMA, Japan - Mitsuo Kodama, who survived the 1945 U.S. atomic bombing of Hiroshima from within a 1-kilometer radius from the hypocenter and was exposed to an extremely high dosage of approximately 4,600 millisieverts of radiation, poses in front of the Atomic Dome in Hiroshima with his book "Hibakusha, Hiroshima karano Message" (Hibakusha, Message from Hiroshima) on March 25, 2014.

DATE, Japan - Photo shows an area where radiation could potentially exceed the yardstick of 20 millisieverts per year in Date, Fukushima Prefecture, on June 16, 2011. The government has decided to designate ''hot spots'' near the Fukushima Daiichi nuclear power plant from which residents will be recommended to evacuate with government assistance due to possible high radiation levels beyond the internationally recommended standard.

TOKYO, Japan - Parents from Fukushima Prefecture protest the Japanese government's safety standards on radiation levels at elementary and middle schools in the nuclear disaster-stricken prefecture as they visited the education ministry in Tokyo on May 23, 2011. On the right is an official of the ministry. The parents demanded the government retract its stance that it is safe for schoolchildren to use school playgrounds as long as the dose they are exposed to does not exceed 20 millisieverts over a year following the nuclear crisis at the Fukushima Daiichi nuclear power station.
