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).
摘要:
在曼尼普尔河谷地区对房屋的钢筋水泥混凝土类型的放射性浓度进行了评估,印度。平均放射性浓度226Ra,232Th,和40K的波特兰水泥分别为39(范围:32-52)Bqkg-1、36(范围:22-62)Bqkg-1和1812(1254-2424)Bqkg-1;对于混凝土,为36(范围:26-45)Bqkg-1,65(范围:45-86)Bqkg-1和(639-681)Bqkg-1,B19-1观察到年有效剂量,平均值为1.9(范围:0.9-3.3)mSvy-1。然而,观察到伽马指数的平均值为1.1(范围:0.5-2.0)。
