85Kr作为一种全球性的气体污染源,主要来源于核燃料后处理厂的排放,半衰期为10.73a,放射出两种β射线(0.173、0.687MeV)和单一γ射线(0.514MeV)。85Kr浓度在1945年为0.1μBq/m3,时至今日已达0.7Bq/m3,日本学者在最新的研究中表明大气中85Kr浓度已超过1Bq/m3。目前用于
As a global source of gas pollution, 85Kr mainly comes from emissions from nuclear fuel reprocessing plants, with a half-life of 10.73a and emission of two β-rays (0.173,0.687MeV) and a single γ-ray (0.514MeV). 85Kr concentration in 1945 was 0.1μBq / m3, up to now 0.7Bq / m3, Japanese scholars in the latest study shows that 85Kr concentration in the atmosphere has exceeded 1Bq / m3. Currently used
