Due to the long half-life of caesium-137 (30 years), the environment of these regions were subjected to contamination, even to this day. A 1972 Brazilian case study on the carcinogenicity of caesium-137 examined the health effects in humans exposed to caesium-137. In 1987, civilians in Goiania, Brazil, were accidentally exposed to caesium-137.

If 1.0 or higher, no taper effect is used. Cesium är självantändligt i luft och reagerar mycket kraftigt med vatten. Den radioaktiva isotopen Cs-137 är en del av restprodukterna från kärnkraftverkens reaktorer. Om cesium antänds i luft brinner den med en klar blå låga. Om cesium får kontakt med vatten sker emellertid en explosiv reaktion: 2Cs+2H 2 O →2CsOH+H 2 The project I'm working on doesn't have any folks who want to turn off the glow. What they want is the glow to reflect more closely the accurate size of the Sun. In STK, the inner "brightest" part of the glow aligns with the actual limb of the Sun, but in Cesium the Sun is far too big (the innermost brightest part of the glow is probably double or more the size of the Sun). If the lead containers of Cs-137 are opened, the substance inside looks like a white powder and may glow.

Het is - naast jodium-131 en cesium-134 - vrijgekomen bij de kernramp van Fukushima. Cesium has a low tendency to adsorb to particles in water, and discharges of 137 Cs from the Windscale Piles could be traced in seawater in the Irish Sea, the north of Scotland, and along the Norwegian coast around Svalbard, not reaching “background concentrations” (originating from global fallout from nuclear weapons testing) until the current, after 6-8 years and 5000-7000 km, reached Strontium-90 A fission product with properties close to calcium. Strontium-90 is with cesium-137 a major radioactive product of nuclear fission.

Cesium-137 is also commonly used in hospitals for SpectrumTechniques.com is the best place (in my humble opinion lol) to get radioactive isotope samples.And yes, this is totally legal in the USA. Outside of Cesium-137 remains an extremely toxic radioisotope, but Prussian Blue provides some help to those who have ingested it.

Caesium-137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid-1980s, caesium-137 was released into the atmosphere, where it was absorbed readily into solution. Known year-to-year variation within that period allows correlation with soil and sediment layers. Cesium-137 is produced in nuclear fission and occurs in atmospheric debris from weapons tests and accidents.
