|A 50 years evolution of cesium-137 in the humann body|
The cesium-137 activity in the human body was measured for nearly half a century, at the the Mol laboratory in northern Belgium. Despite the fact that the laboratory is very far away from the sites of the nuclear tests and of the Chernobyl accident, one observes the strong peak of activity due to the nuclear tests and, about 4 times smaller, the Chernobyl peak. In both cases, the decrease of cesium-137 activity in the human body is much more rapid than the radioactive natural decay with its 30 years half life.
