30 years after the explosion at the nuclear plant in Chernobyl French authorities are still measuring the radio-active levels in the soil and fruits grown here. Not surprisingly the levels are highest in the mountainous regions. Levels of caesium 137 found in various eastern regions exceeds 10000 becquerels* per m2, whereas the norm is 0. More than 95% of fungi from some regions contain significant levels of radioactive material - though they would need to be eaten to excess to be harmful.
* Becquerel is the unit of measurement of residual radioactivity named after Henri Becquerel, collaborator of the Curies discoverers of radioactivity. All 3 received the Nobel prize for physics.
