Sezyum ne işe yarıyor?
Sezyum elementi bir çok organik bileşiğin hidrojenlenmesinde katalizör olarak, atomik saat olarak, fotoelektrik hücrelerde ve vakum tüplerinde, IR lambasında kullanılır ve ayrıca oksijene olan yüksek ilgisinden dolayı elektron tüplerinde gaz giderici olarak da kullanılır.
Sezyum 137 Nedir Nerelerde Kullanılır?
Sezyum 137 elementi ağırlıklı olarak nükleer sanayide kullanılmaktadır. Hatta bu kimyasal element nükleer alanda kullanılan en önemli kimyasal olarak nitelendirilmektedir. Sezyum, radyoaktif olması açısından büyük tedbirler gerektiren bir element olma özelliği göstermektedir.
What are the dangers of cesium-137?
What are the dangers of cesium-137?
The Dangers of Cesium-137. Along with its intermediate half-life, a combination of high-energy radioactivity and chemical reactivity makes cesium-137 a particularly dangerous fission product. Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life…
What is the half life of cesium-137?
What is the half life of cesium-137?
Its half-life of about 30 years is long enough that objects and regions contaminated by cesium-137 remain dangerous to humans for a generation or more, but it is short enough to ensure that even relatively small quantities of cesium-137 release dangerous doses of radiation (its specific radioactivity is 3.2 × 1012Bq/g). [2-4]
What are the practical applications of cesium-137?
Finally, a discussion of its practical applications is beyond the scope of this report, but cesium-137 has received some use as a medical radioisotope for cancer therapies [6,8]. Future research of effective methods for cesium-137 containment and capture may someday alleviate future nuclear crises.
What is the fission product of Cesium 137?
The radioactive isotopes cesium-137 and cesium-134 are significant fission products because of their high fission yield, their long half-lives, and their biochemical similarity to potassium. The fission yield of cesium-137 in nuclear reactions is relatively high, about 6 atoms of cesium-137 are produced per 100 fission events.
