Observation of Hypersensitivity Phenomena in E-Coli Cells after Irradiation by Alpha Particles

In order to study the hypersensitivity phenomena in single strand cells, E-Coli bacteria cultures were irradiated by alpha particles emitted from Am241 point source. The cells showed hypersensitivity at 0.05 Gy. Survival curves models were fitted to the data. The recent hypersensitivity models fitted the data much better than the old conventional models.
