Exponential survival curves were obtained for a dry film culture of bacteriophage T4 Br+ after exposure to both alpha-particles and gamma-quanta. Relative biological effectiveness of alpha-particles was 4.68 with respect to survival. The mutation spectrum after alpha-irradiation slightly differed from that produced by gamma-radiation.
