Dosimetry of ~(12)C Ion Radiation

Dosimetric characteristics of L-α-alanine dosemeter used for dosimetry of ~(12)C ion radiation have been studied.The experimental results indicate that the alanine dosemeter can be used to measure the ~(12)C ion radiation.In addition,dose effects of chromosome aberration dicentrics and cenric rings were studied after human peripheral blood being irradiated by ~(12)C ions;the best regression equation,Y=0.858 503D+0.361 5×10~(-2)D~(2), was obtained within 8.0 Gy.
