Summary

Irradiation by gamma rays resulted in higher D(10) values (P lower than 0.047) than irradiation by electron beam, with the highest values being observed at -15°C. Differences may be attributed to dose rate (1.0 kilogray per hour for gamma, 17 kilograys per minute for electron beam) since it is possible that, at low doses rates, microbial enzymes may have more time to repair damage to the cell due to irradiation, resulting in higher D(10) values.
