Inactivation cross sections for haploid yeast cell strain 211a have been calculated as 1-hit detector based on the track theory in an extended target mode and a numerical calculation of radial dose distribution. In the calculations, characteristic dose D0 is a fitted parameter which is obtained to be 42 Gy, and "radius" of hypo-thetical target α0 is chosen to be 0.5µm which is about the size of nucleus of yeast cells for obtaining an overall agreement with experimental cross sections. The results of the calculations are in agreement with the experimental data in high LET (linear energy transfer) including the thindown region.
