World worst Fukushima nuke pollution

According to France's nuclear monitor the amount of caesium 137 that leaked into the Pacific from the Fukushima disaster was the greatest single nuclear contamination of the sea ever seen.Caesium is a slow-decaying element, taking 30 years to lose half of its radioactivity.This is the biggest single outflow of man-made radionuclides to the marine environment ever observed.

This is twice the concentration that prevailed during atmospheric nuclear testing in the 1960s. Large quantities of iodine 131 also entered the sea as a result of the disaster, caused by the March 11 9.0-magnitude quake that occurred off northeastern Japan. However, significant pollution of seawater on the coast near the damaged plant could persist.
