| Abstract: | 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. |
