Radiation quality affects the efficiency of induction and the molecular spectrum of HPRT mutations in human T cells.

Abstract excerpt

Human T lymphocytes can be used to determine the frequency and molecular spectrum of somatic cell gene mutations induced by ionizing radiations both in vivo and in vitro. In vitro exposure of these G0 cells to low-LET 137Cs gamma rays results in the induction of HPRT mutations and a predominant molecular spectrum of DNA deletions and rearrangements, particularly total gene deletions (11-12%). Similar results are...
