Abstract

Background: The ac vity concentra ons of 226Ra, 232Th and 40K in sand used as building material in Weifang of China were inves gated for evalua ng the radia on hazard. Materials and Methods: sand samples were collected from Weifang and their radioac vity levels were measured using gamma-ray spectrometry. The radia on hazard for residents was assessed by radium equivalent ac vity (Raeq), indoor air absorbed dose rate (D), annual effec ve dose (AED) and excess life me cancer risk (ELCR). Results: The ac vity concentra ons of 226Ra, 232Th and 40K ranged from 11. 7 to 23. 0, 33. 6 to 126. 1 and 353. 2 to 924. 8 Bq kg− 1 with averages of 15. 5, 70. 3 and 802. 9 Bq kg-1, respec vely. All Raeq values were lower than the limit of 370 Bq kg-1. The mean value of D was higher than the world popula on-weighted average of 84 nGy h-1, while the mean AED and ELCR values were below the interna onally accepted values. Conclusions: The use of sand in construc on of dwellings is considered to be safe for inhabitants.
