Abstract

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 gamma-rays (“Lutch Irradiator”, Latenergo, Latvia and “Gamma-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.

Key words
Low doses efficiency; gamma-irradiation; motional activity; paramecium hydrobiontes; doses control.
