The variations in the biological effects caused by continuous and pulsed x radiation were studied on Bombyx mori eggs and on turnip, millet, and endive seeds. The eggs were exposed to 500 to 3000 r, and the pulsed beam had frequencies from 4 to 24 pulses/sec. The seeds were exposed to doses of 1500 and 3000 r, and the pulsed beams had frequencies of 20 pulses/sec. The results on Bombyx mori showed that pulsed irradiation, rather than continuous radiation, had the greater biological effects. This was especially clear with a frequency of 20 pulses/sec. The results obtained with seeds also demonstrated that pulsed radiation doses caused more biological effects than continuous radiation. (J.S.R.)
