Absorbed dose estimates at the cellular level for 186Re and 188Re

Microdosimetric calculations of 186Re and 188Re have been evaluated at the cellular level. Stopping power, LET, range values and deposited energies per decay have been calculated for beta particles, Auger and conversion electrons. In addition, total absorbed doses have been calculated for the radionuclides distributed randomly with certain activities within the cell. Results indicate 186Re and 188Re to be promising radionuclides for therapy of tumors from millimeter through centimeter dimensions.
