Determination of 90Sr, 137Cs, Ca and K in Milk by Radiochemical and Chemical Method
牛奶样品中90Sr、137Cs、Ca和K的测定

A method for determining low-level radioactive nuclides in milk for intercomparison by WHO-IRC is presented in this paper. The results show that the values of 90Sr,137Cs, Ca concentration appear to he agreement with IRC reference values. Some problems concerning the effect on analytical accuracy have been discussed as well.
