On April 26 in 1986, the catastrophe at Chernobyl unit-4 reactor occurred about 100 km north of Kiev in the Ukraine. A lot of radioactivity was released from the damaged reactor into the environment. A vast land and many people living there were contaminated by the radioactivity. After about 7 days the radioactivity reached Japan, a remote country about 8,000 km from Chernobyl and was detected in all the prefectures there. Needless to say, the nuclear facility and its surrounding countryside have been highly polluted by the radioactivity. Naturally this radioactivity was found in people's bodies, too. The high concentration of 300 Bq/Ag (24,000 Bq at weight of 79 kg) was detected in the inhabitants living in Checherusk about 200 km north of Chernobyl in 1991. Some estimations of 10,000 to 400,000 deaths in the future due to cancer caused by the accident were reported. A catastrophe at only one nuclear reactor leads to global pollution by radioactivity and inflicts damage on people.
