In several systems a paradoxical reduction of radiation damage with increasing dose, termed reversion, has been observed. In the fern Osmunda regalis the percentage of cells which does not die but stays alive, although reproductively sterile, increas

Survival curves were constructed and D0 values determined after X-irradiation of single-celled germinating spores of 14 species of ferns, which had a wide variation in interphase chromosome and nuclear volumes and in DNA content per chromosome and pe

The unicellular green fresh-water desmid Closterium moniliferum, when irradiated at high dose-rate with 10 MeV electrons, yields a survival curve with a threshold to a dose of about 10 krads, followed by a shoulder and an exponential decline. Previou

Cells of the desmid Closterium moniliferum are more resistant to killing by radiation if they are previously exposed to relatively small doses of ionizing radiations (14-MeV neutrons, 290-kVp X ray...

When exposed to fast electrons at high dose rate, all cells of Closterium moniliferum survive (form colonies) up to a threshold dose of about 10 krad. If previously exposed to a dose between 0.14 and 10 krad they can survive higher threshold doses. W
