These are stone structures and again not bombarded by radiation on a daily basis.
Radiation does not damage the structural integrity of anorganic materials in a way that would endanger them.
Nonsense - and again no sources....
To rebut and from a very pro-nuke source:
The effects of low doses, <1010 neutron/cm2 or <1010 Gy gamma, of
radiation over periods of less than 50 years do not seem to have a significant
effect on the concrete. Longer-term exposure, over 100 years, has not been
The effects of higher doses of radiation are not as clear, and some
difference in reported results exists. For some concrete types, neutron exposures
>1010 neutron/cm2, are reported to cause deterioration.
For high radiation exposure, >1020 neutron/cm2 or >1010 rads of gamma,
concrete has been reported to exhibit reduction in compressive and tensile
strength and a marked increase in volume.
The effects of long-term exposure of concrete to elevated temperatures are
a loss of water in the concrete leading to a decrease in compressive strength,
changes in the modulus of elasticity, creep resistance, conductivity, and
diffusivity. Generally speaking, the threshold of degradation is 95C, and the
effects increase with increasing temperature and time exposure.
