1) Activity of Caesium-137
137Cs活度浓度
2) 137Cs activities
137Cs比活度
1.
137Cs activities in purple surface soil on grass land have a good relationship with the medium grain size(d50)by sieving method,but do not have a defined relationship with the medium grain size(d50)by normal method.
紫色土草地表层土壤的137Cs比活度与样品的筛分中值粒径(d50)相关较好,而与颗分中值粒径没有明显的相关性。
3) 137Cs activity
