EFFECTS OF MIXED REACTOR RADIATION ON CELL DIVISION OF SYNCHRONIZED TETRAHYMENA PYRIFORMIS,
Abstract
This paper reports the effects of mixed, neutrongamma, reactor radiation on cell division of synchronized Tetrahymena pyriformis, a ciliate protozoon. These effects of reactor radiation are compared with the effects of 250 kvp X-radiation in the range of 0-100 krads. Reactor radiation delays cell division more efficiently than does X-radiation; the relative potency is 1.3. The dosage response curve is biphasic in both neutron-gamma-irradiated and X-irradiated cells. In the range 0 to 16-20 krads, the division delays appear to follow a saturation-type curve. Above these values, the division delays appear to be linearly related to dose. (Author)
