AI Article Synopsis
- An assessment of radioactivity in various building materials (reinforced cement concrete, sand, and bricks) in Manipur, India, measured levels of 226Ra, 232Th, and 40K with notable variations across materials.
- Average radioactivity concentrations ranged from 30 to 1812 Bqkg-1, with specific values for each material type indicating concrete and sand had higher levels of certain radionuclides.
- The annual effective dose from these materials was calculated at an average of 1.9 mSvy-1 and a gamma index of 1.1, suggesting moderate exposure levels to radiation in the region.
Article Abstract
An assessment of radioactivity concentration of reinforced cement concrete types of house was conducted in the valley region of Manipur, India. The average radioactivity concentration of 226Ra, 232Th, and 40K of portland cements are 39 (range: 32-52) Bqkg-1, 36 (range: 22-62) Bqkg-1, and 1812 (1254-2424) Bqkg-1; for concrete are 36 (range: 26-45) Bqkg-1, 65 (range: 45-86) Bqkg-1, and 660 (639-681) Bqkg-1; for sand are 45 (30-61) Bqkg-1, 114 (range: 55-212) Bqkg-1, and 1859 (range: 1413-2232) Bqkg-1; and for bricks are 30 (range: 24-37) Bqkg-1, 148 (range:79-184) Bqkg-1, and 1444 (range: 1093-2103) Bqkg-1, respectively. The annual effective dose was observed with an average value of 1.9 (range: 0.9-3.3) mSvy-1. However, gamma index was observed with an average value of 1.1 (range: 0.5-2.0).
