| On the basis of what radioactive levels existing in soil and rice around Hanzhong region of Shaanxi Province were studied as the references (1) and (2), the following problems have been discussed in this paper: the transmitted coefficient of radioactive nuclides from soil to rice, U-Ra equilibrium coefficient in soil and rice, the relationship between nuclide content in rice and the paddy species, the ratio of nuclide contents in rice and in rice bran, rice polluted by radioactive nuclides in the course of harvesting and husking, and viriations of nuclide content in rice after washing. |
