Micronucleus induction in 10 human tumour cells after high- and low-dose radiation.


A number of data measuring survival of animal or human cells to low LET ionizing radiation have demonstrated that these cells may be hypersensitive to doses below 1 Gy, possibly due to the absence of an inducible repair mechanism, which is observed at higher doses. The production of micronuclei (MN) in cells exposed to ionizing radiation reflects genotoxic… (More)
