Abstract
A PREVIOUS communication1 reported some quantitative data on the effects of continuous irradiation of HeLa cells grown as a monolayer. The incorporation of a suitable quantity of tritiated water in the growth medium provided a uniform source of radiation. An effect was noted with a dose-rate as low as 30 rads/day, when cells were repeatedly sub-cultured. Cells have now been exposed to such continuous irradiation for more than twelve months and this communication reports changes in the chromosome number of the continuously irradiated cells.
