高暴露量建筑材料γ辐射剂量率的实验与模拟

Experimental and Simulation of Gamma Radiation Dose Rate for High Exposure Building Material

Akbar Abbasi, Mustfa Hassanzadeh

摘要:

伊朗通常使用高辐照建筑材料中的天然放射性浓度,使用γ射线光谱法直接测量辐照量。~(226)Ra、~(232)Th和~(40)K的值分别在3.8 - 94.2、6.5 - 172.2和556.9 - 1539.2 Bqkg ~(-1)之间。用MCNPX程序计算了238 U、232 Th系列和40 K在标准居室内的吸收剂量率。模拟和实验结果分别为7.95 - 41.74和8.36 - 39.99 nGy h-1。这些结果与实验结果进行了比较,有密切的重叠。模拟结果能够适用于任何类型的居住场所。

英文摘要:

Natural radioactivity concentrations in high exposure building materials are commonly used in Iran, which is measured a direct exposure by using γ-ray spectrometry. The values for 226Ra, 232Th and 40K were in the ranges 3.8 - 94.2, 6.5 - 172.2 and 556.9 - 1539.2 Bqkg-1, respectively. The absorbed dose rates in the standard dwelling room due to 238U, 232Th series and 40K were calculated with MCNPX code. The simulation and experimental results were between 7.95 - 41.74 and 8.36 - 39.99 nGy h-1, respectively. These results were compared with experimental outing and there was overlap closely. The simulation results are able to develop for any kind of dwelling places.
