概要

It was attempted to estimate the absorbed doses in cell after incorporation of tritium with the constant absorption model. The point source dose distribution, the dose distributions due to tritium locally incorporated, the fraction of self-absorption in spherical source and the fraction absorbed in sphere of energy emitted from the source around the sphere could be analytically calculated with the constant absorption model, where the beta-spectrum was divided into eighteen one-keV intervals and the beta-particles were supposed to have the middle energy in each energy group. Furthermore the results were compared with the other ones and the questionable points contained in these estimation methods investigated. Then it was pointed out that the stopping power and the transmission probability of low-energy electrons would be required to be established theoretically and experimentally.
