文摘In India,bricks as building materials are mainly prepared by clay using the deposited sediments of rivers,and the radionuclide contents in bricks and brick-making clays should vary with origin and geological condition.In this paper,the radionuclide contents of these materials from river bank areas of Cuddalore district,Tamilnadu India are measured by gamma ray spectrometer using NaI(Tl) detector,and compared with those of other countries.The radiation hazard indices,which are evaluated by radium-equivalent(Raeq) activity,are lower than that of NEA-OECD.
