Inactivation of phage phiX 174 by accelerated ions enhanced delta-ray effect by air layer in front of the samples. [. cap alpha. particles and neon ions]
Different inactivaion rates of phage phiX 174 were observed between two irradiation method for charged particles. In method EA, phage particles were spread on a thin film and exposed to air during irradiation. In method CF, the phage sample was covered with a thin polycarbonate film to eliminate the effect of secondary electrons ejected from air in front of the sample. The apparent inactivation efficiency of primary particles determined by method EA was found to be higher than that found by method CF in the case of both ..cap alpha..-particles and nitrogen ions. The observed increase in inactivation can be explained by the dispersed energy loss of secondary electrons produced in air as compared with those produced in polycarbonate.
