Radiation Hormesis of Radish Using an X-Ray Photography Device

Abstract

Radiation hormesis was studied at an X-ray photography room. Seed of radish (Kaiwaredaikon) was irradiated by X-ray, from 10 to 3000mGy. Since the growth of plant was the highest around 500mGy, 100 seeds were irradiated at a dose of 500mGy. Fifty seeds were selected and the growth rate was measured after 1 and 2 weeks. After 2 weeks, the growth of the seeds irradiated (129±5mm) was found to be higher than those without irradiation (115±5mm) .
