The regularization algorithm based on the Tikhonov's method of generalized discrepancy has been developed for Fredholm integral equations of the 1-st kind with complex-valued functions and applied for the solution of the corresponding inverse scattering problem.

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<sup>−6</sup> to 10<sup>−2</sup> W/cm<sup>2</sup>. Different experimental models revealed different sensitivity to low-level radiation. The most sensitive to low-level radiation was the Artemia sp. hatching percentage (10<sup>−6</sup> Wcm<sup>2</sup>). Human cells were less sensitive to radiation (10<sup>−4</sup> W/cm<sup>2</sup>). Irradiation of more power (10<sup>−3</sup> W/cm<sup>2</sup>) 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.","PeriodicalId":124478,"journal":{"name":"2010 5th International Confernce on Ultrawideband and Ultrashort Impulse Signals","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128265084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
