In the assessment of the radiation risk by intake, the doses per unit intake, also called dose coefficients, are necessary to use. It is not possible to measure the radiation dose to tissues of the body, dose coefficients must be based on biokinetic and dosimetric models. This paper describes the current status of the document prepared by committee 2 of ICRP, which is to assess the reliability of the dose coefficients for members of the public. Specifically the goal is to assess (1)the uncertainty in the effective...

In the assessment of the radiation risk by intake, the doses per unit intake, also called dose coefficients, are necessary to use. It is not possible to measure the radiation dose to tissues of the body, dose coefficients must be based on biokinetic and dosimetric models. This paper describes the current status of the document prepared by committee 2 of ICRP, which is to assess the reliability of the dose coefficients for members of the public. Specifically the goal is to assess (1)the uncertainty in the effective dose coefficient as central estimators of the population and (2)the variability of effective dose coefficients among members of the population. The methodology introduced by committee 2 consists in separating the dose calculation into four models (GI, respiratory, systematic biokinetic, dosimetric models). The uncertainties obtained in each model will then be combined to estimate the total uncertainty. (

在评价公众成员摄入放射性核素的辐射危害时,需估算每单位摄入量所致的剂量(即剂量系数)。摄入放射性核素后器官或组织所受到的剂量是通过生物动力学模型和剂量学模型来确定的,因此剂量系数也必须根据模型来确定。文中初步探讨了国际放射防护委员会(ICRP)给出的剂量系数的可靠性问题。文中首先说明了估算剂量系数的概念和方法,然后分析了剂量系数估算中,采用胃肠道模型、呼吸道模型、系统生物动力学模型和剂量学模型时所遇到的不确定度的各种主要来源。

Somatic HPRT gene mutations induced by exposure of 0~4 Gy 60 Co γ ray have been studied with the multinuclei cell method. The scopes of application and problems to be encountered in the radiation bio dose estimation using somatic HPRT gene mutations were approached. It was shown that the frequency of HPRT gene mutation was fitted in with a linear quadratic model of Y=0.4022+0.2710D-0.0460D 2 in the 0~4.0 Gy range and more fitted to a linear model of Y=0.3827+0.2948D in the low dose range of 0~1.0...

Somatic HPRT gene mutations induced by exposure of 0~4 Gy 60 Co γ ray have been studied with the multinuclei cell method. The scopes of application and problems to be encountered in the radiation bio dose estimation using somatic HPRT gene mutations were approached. It was shown that the frequency of HPRT gene mutation was fitted in with a linear quadratic model of Y=0.4022+0.2710D-0.0460D 2 in the 0~4.0 Gy range and more fitted to a linear model of Y=0.3827+0.2948D in the low dose range of 0~1.0 Gy. The HPRT gene mutation frequencies had better linear relations with chromosome aberrations and micronuclei. The results show that HPRT mutation can be used in the dose estimation of low LET radiation, especially applied to detection of monogenic mutation and assessment of radiation risk.

Objective] This study is to explore the microwave hazard irradiated by interphones. [Methods] We tested the radiation intensity of the interphones and investigated the health in the users. [Results] When the interphones started,at beginning there appeared the maximum of the radiation intensity,then the intensity was reduced and become relatively stable. The value of the radiation intensity became lower with the distance increased; the rate of symptoms in exposure group was higher than that in control group....

[Conclusion] The radiation intensity of most interphones is higher than the current standard and they should be controlled.
