Shuitu Baochi Xuebao, 2004 通过测定东北黑土背景点样品中137Cs活度,探讨了土壤剖面中137Cs的分布特征,对因风蚀造成背景点土壤表层137Cs的沉积进行了校正,得出了黑土的137Cs背景值,为水蚀风蚀两相侵蚀地区土壤137Cs背景值的确定提供了新思路。结果表明:黑土背景点土壤剖面中137Cs比活度的分布呈指数型,其拟合方程为Cs=76.744e-0.2566h,相关系数达到0.994。剖面中75.7%的137Cs分布在0～5cm的表层中,92.5%的137Cs分布在0～10cm的土壤上层;黑土的137Cs背景值为2463 ...

137Cs in fishes of Kanevskoe reservoir after 20 years from ChNPP accident [PDF]
Ядерна фізика та енергетика, 2006 Content of 137Cs in fishes of Kanevskoe reservoir of r. Dnepr was studied during 2005 - 2006. It is revealed, that levels of the content of 137Cs in comparison with 1986 have decreased approximately in 10 times.

Scintillation detectors constructed with an optimized 2x2 silicon photomultiplier array
, 2016 Silicon photomultipliers (SiPMs) are a good alternative to photomultiplier tubes (PMTs) because their gain and quantum efficiency are comparable to PMTs. However, the largest single-chip SiPM is still less than 1~cm$^2$.
