【 摘 要 】

The open literature and accessible United States Department of Energy-sponsored reports were reviewed for the effects of radiation and temperature on concrete. No effects of radiation were found for exposures less than 1010 neutron/cm2 or 1010 Gy gamma for periods less than 50 years. Reductions in compressive and tensile strength and a marked increase in volume are reported for exposures greater than 1020 neutron/cm2 or 1010 rads of gamma. There are conflicting reports of damage for doses in the middle ranges.
