Effect of LET and microdistribution of radiation on the transformation in vitro and in vivo. Comprehensive progress report
Work has involved the following three areas: (1) an investigation of the mechanisms of radiation carcinogenesis by studying the events involved in the process of malignant transformation of mouse 10 T-1/2 cells; (2) an investigation of the effects of promoting agents on radiation-induced transformation in vitro; and (3) an investigation of the induction of transformation by internally emitting radionuclides incorporated into cellular DNA. The latter area has been extended to include studies of mutagenesis by these radionuclides in human lymphoblasts, and molecular measurements of DNA strand breaks. During the past year, research has focused on the first area, as well as on studies of the mutagenic effects of incorporated radionuclides.
