The activity concentrations of 226Ra, 232Th and 40K in four common types of building materials (carbonate, quartz, clay and granite) in North Vietnam were determined by HPGe gamma-ray spectrometry. The average activity of these radionuclides were 15, 17 and 213 Bq kg−1 for carbonate; 43, 35 and 462 Bq kg−1 for quartz; 80, 99 and 824 Bq kg−1 for clay; and 98, 198 and 1440 Bq kg−1 for granite. The results showed significant differences in the activities of these radionuclides in different building materials as follows: ACarbonate < AQuartz < AClay < AGranite. The radioactivity of building materials originated from granite and clay are high, while those observed for ones derived from carbonate and quartz are low. Regarding radiation hazard indices, granite exceeded the recommended value, while carbonate fell below this maximum. [ABSTRACT FROM AUTHOR] |
