Abstract
The absorbed doses in a cell nucleus from β-particles emitted by incorporated tritium atoms in the nucleus are estimated on the basis of energy dissipation algorithm as follows ; the energy dissipated at depth t by a beam containing one electron/cm2 may be represented as d(ηE)/dt, where η is the probability of transmission and E the residual energy.
The absorbed doses which were calculated with constant absorption model in the previous work are found to agree well with the present results. It is known that the results which are obtained by using the average energy of 3H β-particles are appreciably different from the ones based on the β-spectrum.
Furthermore the calculated results are compared with the other estimation methods and the conclusions deduced from these models are briefly explained.
