摘要：

Five types of building material of different quality and from different sources were analyzed for uranium and thorium using instrumental neutron activation analysis /INAA/. The concentration of thorium was found to be about 3-5 times higher than uranium while the activities were about the same. The total activities of both elements was found to be between 1-4 pCi g-1. © 1990 Akadémiai Kiadó.
