Survival of human epithelial cells irradiated with cobalt 60 as microcolonies or single cells
1 Jan 1997
Abstract excerpt
Microcolonies of one to >50 cells were irradiated. They were assayed for survival using the Puck and Marcus clonogenic technique and the distant progeny were tested for expression of lethal mutations. The results show that epithelial cell colonies appear to respond as a unit rather than as individual cells to a radiation dose and the uncorrected initial surviving fraction is relatively constant irrespective of...
