Meaning that now, some 30 years after the Chernobyl Disaster, it should theoretically be a lot safer, per my limited understanding of the half-life of chemicals. After the Chernobyl accident, increased cesium-137 body burdens were measured for 22 Japanese male adults. An average biological half-time of 101 days was estimated. In the 1960s, an average Cs biological half-time of 86 days was reported for 23 Japanese male adults under quasi-equilibrium conditions in regard to cesium-137 from atmospheric nuclear weapon tests. The absorbed doses by gamma-photon radiation were from cesium-137 (137 Cs) in soil contaminated by the two major NPP accidents. More serious and wide-spread impacts of the Chernobyl NPP accident on soil contamination in Ukraine, Belarus, Russia and countries as far as Sweden and Greece were due to the inland location, radiative plume transport pathway and high 137 Cs emission strength (9 times Radiocesium (Cs-137) does not occur naturally on earth, it is exclusively anthropogenic in origin for example through nuclear fission.
The trial was conducted during the simultaneous one-month stay in the sanatorium Silver Spring. In this clean radiological environment only radiologically "clean" food is given to the children. Chernobyl 25 years ago; radioactive Cesium 137 cloud over Russia and Europe.

The Fukushima reactor, however, has so far released 360,000 TBq of cesium-137, according to TEPCO.
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. Östra Västmanland belonged to the areas that were to some extent affected by radioactive waste in connection with the Chernobyl disaster 35 years ago.

Vi har mätt cesiumhalten i blåbär, lingon, gul kantarell och trattkantarell på fem olika platser i kommunen under många år sedan Tjernobylolyckan inträffade 1986. Cesium är ett radioaktivt ämne som finns i vissa livsmedel, främst insjöfisk, vilda bär och svamp samt kött av ren, älg, rådjur och får. Som invånare i Sollefteå

After the rapid decay of iodine-131, cesium-137 was the predominant source of radiation in fallout from the Chernobyl explosion. Particles of the reactor fuel settled densely within about 100 km or their release, and within a 30 km radius of the facility, cesium radioactivity due to ground deposition of fallout particles was over 1.5 × 10 6 Bq/m 2 . The concn of cesium-137 measured in groundwater wells at Carlsbad, NM (the site of project GNOME) ranged from 99 to 6.8X10+5 pCi/L in 1997 (2). The concn of cesium-137 in groundwater at the Chernobyl nuclear power plant was in the range of 40.5 to 1,100 pCi/L in 1988 and 29.7 to 129.7 pCi/L in 1989 (3).

Mar 2, 2017 evacuations following the Chernobyl nuclear disaster. The Cesium-137 decay chain is a relevant example of a beta decay followed. In case of nuclear accident, the focus of monitoring will be mostly on the release of noble gases, I-131 and Cs-137. As these are the only accidents have been Sep 24, 1986 The conclusion is based on study of the amount of cesium-137 released by the explosion and fire at the Chernobyl nuclear power plant about Apr 21, 1989 “Global contamination by Cs-137 and Sr-90 and exposure dose over the USSR territory”.

The Fukushima reactor, however, has so far released 360,000 TBq of cesium-137, according to TEPCO. In 2005, IRSN produced a simulation of the path travelled across Europe by the radioactive cloud folowing the Chernobyl accident. This simulation was produced using a new generation of operational atmospheric dispersion models developed for use in case of nuclear emergency. To qualify this new long-distance dispersion model, IRSN experts applied it to the atmospheric release of caesium-137 Césium 137. 143 likes. No total 1000 pessoas foram expostas aos efeitos do césio 137, destas, 129 pessoas apresentaram contaminação corporal interna e externa.
Iodine-131, dreadful in the weeks following the disaster, has disappeared because of its 8 days radioactive half-life (or period). On the contrary, because of their periods of thirty years, the effects of cesium-137, and to a lesser degree those of one other radioactive element, strontium-90, are still being felt. After the rapid decay of iodine-131, cesium-137 was the predominant source of radiation in fallout from the Chernobyl explosion. Particles of the reactor fuel settled densely within about 100 km or their release, and within a 30 km radius of the facility, cesium radioactivity due to ground deposition of fallout particles was over 1.5 × 10 6 Bq/m 2 . For cesium-137, which persists in the soil and produces gamma rays that have hundreds of thousands of times more energy than rays of sunlight, the half life is about 30 years. The concn of cesium-137 measured in groundwater wells at Carlsbad, NM (the site of project GNOME) ranged from 99 to 6.8X10+5 pCi/L in 1997 (2). The concn of cesium-137 in groundwater at the Chernobyl nuclear power plant was in the range of 40.5 to 1,100 pCi/L in 1988 and 29.7 to 129.7 pCi/L in 1989 (3).
