A fish heterogeneous phantom is developed for using in the evaluation of radiation environment. Taking account of the current situation of the natural fishery resources, aquaculture and fishery management in the coastal waters of China, the authors select a fusiform 25 cm in length as the external form on the whole and regard the anatomic organs of Lateolabrax japonicus as the elementary internal organs. The fish phantom consisting of 10 kinds of organs gives the mathematical descriptions of the organs, and with the Monte Carlo method also gives the absorbed fractions in various organs within the heterogeneous phantom for monoenergetic photon sources uniformly distributed in the organs. Dose rates to genital gland of Y-rays of per unit concentration of 29 kinds of radionuclides from various organs in the fish phantom are also given.

选择在我国沿海常见且经济意义重要的纺锤型作为基本外形,以养殖和捕捞上常见的商品规格作为大小,以解剖学上较典型的鲈作为参考,尝试建立了一个作为辐射环境评价使用的、由10类器官(或组织)组成的鱼类剂量率估算解剖模型,给出了各器官的数学描述,并用蒙特卡罗方法详细计算了单能光子在各解剖器官间相互的能量吸收分数。最后给出了各器官内常见的29种核素单位浓度的不同γ成分对性腺产生的吸收剂量率。

Taking account of the issue resulted from using NRC's (America Nuclear Regulatory Commision) plume depletion curves and deposition curves for radiation environmental assessment, as well as the effect of particle size distribution of effluents, this paper calculates the residual fraction of plume and the relative dry deposition rate with source depletion model employing the dry deposition velocities which was measured in our country for three modes particles (Altken mode, accumulation mode and the coarse mode),...

Taking account of the issue resulted from using NRC's (America Nuclear Regulatory Commision) plume depletion curves and deposition curves for radiation environmental assessment, as well as the effect of particle size distribution of effluents, this paper calculates the residual fraction of plume and the relative dry deposition rate with source depletion model employing the dry deposition velocities which was measured in our country for three modes particles (Altken mode, accumulation mode and the coarse mode), and the results for the three mode particles are respectively compared with NRC's results. The results show that there are a obvious differences between them. However, the particle size distribution of effluents should be taken into consideration adequately and the deposition velocities should prudently be selected in Radiation environmental assessment. (

考虑到在辐射环境评价中使用 NRC(美国核管理委员会 )耗减曲线和沉积曲线时存在的问题 ,以及流出物粒径分布的影响 ,本文用国内实测的 3种粒径分布粒子的干沉积速度用源耗减模式计算了烟羽残留份额和相对干沉积率 ,并分别与 NRC的结果进行了比较。结果表明 ,本文计算的 3种模态 (爱根核模态、积聚模态和粗模态 )粒子的烟羽残留份额曲线和相对干沉积率曲线都与 NRC的结果有明显的差别。在辐射环境评价中要充分考虑流出物的粒径分布 ,谨慎选择沉积速度。
