Experimental Study of Relationship between Biological Hazards of Low-Dose Radiofrequency Exposure and Energy Flow Density in Spirostomum Ambiguum Infusoria Exposed at a Mobile Connection Frequency (1 GHz)

Bulletin of Experimental Biology and Medicine Aims and scope

Radiofrequency exposure at the mobile connection frequency (1 GHz) at different energy flow densities, 5 μW/cm2 (2-fold below the maximum permissible level) and 50 μW/cm2 (5-fold surpassing this level), caused a reduction of motor activity in unicellular hydrobionts Spirostomum ambiguum Ehrbg infusoria. In all cases, the effect was similar by the intensity and developed in a jump-wise manner after exposure of a certain duration, after which did not increase with prolongation of the exposure. The duration of radiofrequency exposure safe for the object varied signifi cantly: 8–9 h and 10 min at 5 and 50 μW, respectively. These innovation data on harmful biological effects of very low radiofrequency exposure (5 μW/cm2), the threshold form of biological reaction, presence of “safe” periods of exposure, and the data demonstrating a clear-cut relationship between these periods and energy flow density are interesting from theoretical viewpoint and in connection with the problem of evaluating permissible levels of radiofrequency exposure of biological objects.
