The survival ratios of yeast cells as a function of carbon beam penetr
ation into a plastic block were evaluated at an initial energy of 135
MeV/amu. The cells were inserted into holes at several depths along th
e beam path. We estimated the inactivation ratios of both the haploid
and the budding response of the haploid cell for the wild and the sens
itive strain at stationary and growth phase. The ratios along the beam
path were applicable as a method of beam adjustment in the planning o
