Radiometric analysis of some building materials using gamma-ray spectrometry

The present study focuses on the effect of natural radioactivity of some common building materials to humans. The main radiological risk assessment parameters such as radium equivalent, dose rate, annual effective dose equivalent and hazard indices were determined using Gamma ray spectrometry for individual building materials and their three different combinations. On comparing the results with world average values, it is inferred that the building materials do not pose any radiation hazards. Also as all the radiological parameters for M-sand are much lesser than that of river sand, it can be a good replacement for river sand.
