Cesium-137 and its decay product, barium-137m, are used for sterilization activities for food products, including wheat, spices, flour, and potatoes. Problem 1 Cesium 137 (spilled at Chernobyl) has a half life of approximately 250 years when in soil. At the time of the spill, 1000 grams of radioactive substance is measured in the soil. The equation A(t) = 1000 - 2 250 Represents the amount of Cesium 137 that is in the soil as a function of years since the spill occurred, t. The Atlas, which was compiled under the Joint Study Project (JSP6) of the CEC/CIS Collaborative Program on the Consequences of the Chernobyl Accident, implemented into the European Commission's Radiation Protection Research Action, summarizes the results of numerous investigations undertaken throughout Europe to assess the ground contamination by cesium-137 following the Chernobyl accident. 137 Cs is taken up into organisms through the same routes as potassium, and the ability of cells to transport potassium against concentration gradients to obtain high intercellular concentrations also leads to a fairly high bioconcentration of radioactive cesium. After the Chernobyl accident in 1986, a considerable amount of 137 Cs was deposited in the northern and central parts of Scandinavia, and in a large number of Swedish lakes, the 137 Cs content of the fish exceeded the limit (1500 Bq Cesium-137 is a gamma emitter with a half-life of 30.08 years.

Cesium 137's half-life It could be that new cesium is blowing over the soil sites from closer to the Chernobyl site. Or perhaps cesium is migrating up through the soil from deeper in the ground.

The lingering effects of the Chernobyl nuclear catastrophe in 1986 in Ukraine continue to affect entire eco-systems in Europe. An example of such effects is the radioactive contamination (cesium-137 contamination) of wild mushrooms in certain European countries.

Context: Since the half-life of 137Cesium is 30.17 years, part of the radioactivity in the affected regions is still present today, and it is usually still detected in the food chain, although at lower concentration levels.

It still exists in the earth in the areas affected by the Chernobyl accident, including Moreover, the IAEA and the WHO report did not discuss the Chernobyl fallout and radiation dose in any other countries, except in Belarus, Ukraine and Russia. 80% of the territory of Moldova, as well as European part of Turkey, Slovenia, Switzerland, Austria and Slovakia have been contaminated by cesium-137 with more than 4 kBq per square meter.
