Low dose-rate effects of cesium-137 and iodine-125 on cell survival, cell progression, and chromosomal alterations.

Abstract

Chinese hamster ovary (CHO-AA8) cells in exponential growth were exposed to graded doses of radiation from iodine-125 (I-125) or cesium-137 (Cs-137) at various low dose rates, then monitored for cell number and clonogenic integrity. Cellular kinetics and the induction of sister chromatid exchanges and chromosomal aberrations were evaluated in cells after… (More)
