Abstract

To explore the effects of different linear energy transfer(LET）of ¹²C⁶⁺ ion Beam irradiation on BJ1, survivals and biocontrol effects were cultured and treated with LET＝40 and 60 keV/μm at the doses of 50, 100, 200, 400 and 600 Gy, respectively. The results showed more mutations and biocontrol charts and higher survivals were obtained with high LET(60 keV/μm） irradiations at lower dose, which was useful to screen good positive mutations. Based on the results above, it could be concluded that the condition of high LET(60 keV/μm） had obvious mutagenic effects than that of low LET(40 keV/μm）.
