Abstract :
Research works on biological effects of ultrawideband pulsed radiation which were realized in the Kharkiv National University are summarized. Investigations were done on different biological objects: human cells, Artemia sp., Drosophila melanogaster. Biological effects of ultrawideband pulsed radiation were observed in a range from 10-6 to 10-2 W/cm2. Different experimental models revealed different sensitivity to low-level radiation. The most sensitive to low-level radiation was the Artemia sp. hatching percentage (10-6 Wcm2). Human cells were less sensitive to radiation (10-4 W/cm2). Irradiation of more power (10-3 W/cm2) induced dominant lethal mutations (DLM) in Drosophila. In our opinion, the most appropriate method for assessment of biological effects of irradiation is evaluation of heterochromatin granules quantity (HGQ) in human cells.
