摘要：

This paper is a proposal to evaluate radioactivity of coal fly ash used in cement according the national standard titled “Limits of radionuclides in building materials”. Because concrete includes cement and nature materials with low radioactivity, we propose that the limits of radionuclides in cement contained coal fly ash can be two times relaxed than that of this national standard, and the limit of the internal exposure index on cement may be unnecessary. There is no obviously increase of the Rn-222 exhalation rate from aerated concrete blo...
