X線撮影装置を利用したカイワレダイコンの放射線ホルミシス Radiation Hormesis of Radish Using an X-Ray Photography Device
<I>Radiation hormesis was studied at an X-ray photography room. Seed of radish (Kaiwaredaikon) was irradiated by X-ray, from 10 to 3000</I>mGy. <I>Since the growth of plant was the highest around 500</I>mGy, <I>100 seeds were irradiated at a dose of 500</I>mGy. <I>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</I>±<I>5</I>mm) <I>was found to be higher than those without irradiation (115</I>±<I>5</I>mm) .
