Abstrakt: The increase in the electrical resistivity of 99.98% pure thorium per unit electron flux was measured as a function of incident electron energy from 1.6 to 2.8 MeV. During irradiation, the temperature of foil samples was held below the temperature of the fist major recovery peak at 10°K. For unit displacement probability, the theoretical displacement cross-section best reproduces the experimental damage rates at an effective threshold displacement energy of 35 eV and a Frenkel resistivity of 15 × 10−4 ohm-cm per unit fractional concentration of Frenkel pairs.
