Abstract

Concentrations of natural radionuclides (226Ra, 232Th, 40K) were measured in soil, sand, cement, clay, and bricks used as building materials in Tiruvannamalai, India. Radiological hazard indices, annual dose estimates, and cancer risk assessments were computed and found to be within safe limits. Multivariate statistical analysis (PCA, HCA) was used to determine relationships among samples, with PCA explaining 94.9% variance and clustering samples into four groups.
