[Modification of the damaging effect of alpha-particles on Escherichia coli K-12 by low-intensity laser irradiation]
Abstract:
A study was made of the combined effect of laser (helium-neon laser, lambda = 633 nm) and alpha-radiation on survival of Escherichia coli K-12 cells of different genotypes. Pre- and post-irradiation exposures to laser-radiation diminished the damaging effect of alpha-particles. In the latter case, modification of survival was more pronounced.
