THE EFFECT OF COMBINED APPLICATION OF ULTRAVIOLET AND X RAYS UPON THE MUTAGENIC PROCESS IN STREPTOMYCES AUREOFACIENS LC-B16 (in Russian)
The effects of ultraviolet rays and x rays on spores were studied, both singly and combined at 1, 2, and 3 hour intervals. The tabulated results show that the lethal effect of the combined irradiation taken at arbitrary succession is considerably below the expected cumulative effect. Experiments indicate that the ultraviolet rays seem to weaken the lethal effects of the succeeding x rays. The effects of the combined irradiation on the Streptomyces aureofaciens LC-B16 mutation and the effects related to the time interval between irradiations are tabulated. The mutation frequency in treatments by x rays followed by ultraviolet rays is considerably higher than in the reverse order of irradiation. Preliminary treatment with ultraviolet rays lowered the efficiency of the following x radiation. (R.V.J.)
