Comparison of the low doses efficiency of γ-irradiation to the spirostomum ambiguum at the γ-cell and Lutch irradiator. Doses control

The decrease of the spontaneous motional activity of paramecium Spirostomum ambiguum Ehrbg was observed just after irradiation in the 0.01 Gy at the different irradiators with 60Co γ-rays (Lutch Irradiator, Latenergo, Latvia and γ-Cell, Canada). It was approximately on the similar level (about 40 % below control) in variety of doses (to 1.0 Gy inclusive). The present result has been interesting in the question of the low doses irradiation activity on the biota.
