作为辐射防护的基本原则之一，防护最优化受到越来越高度的重视，这使得对辐射的危害代价进行贷市化估价变得更迫切。考虑到问题本身的复杂性，单纯从经济角度研究的局限性是可想而知的。但本文结合国情先从经济角度加以研究，至少也可以为以后的深入研究提供一个初步基础。本文在调查了我国１５０００多例癌症治疗费用以及相关的其它数据的基础上，结合辐射的危险度因子，估算出了辐射危害代价α值。它是随个人剂量的变化而变化的，在个人剂量不高于１ｍＳｖ／ａ时，α约为６６００元／人·Ｓｖ（以１９９０年计）。在估算过程中，各个与经济有关的数据都根据国家统计局公布的资料，所估代价可能偏低。
As one of the basic principles of radiation protection, the protection optimization has received more and more attention, which makes it more urgent to carry out loan-oriented valuation on the harmful cost of radiation. Taking into account the complexity of the problem itself, the limitations of the study from an economic point of view can only be imagined. However, this paper, based on the actual conditions of the country to study from an economic point of view, at least for future research can provide a preliminary foundation. Based on a survey of more than 15000 cancer treatment costs and other related data in our country, the α value of the radiation damage cost is estimated based on the radiation risk factor. It varies with the individual dose and is about 6,600 yuan / person · Sv (in 1990) when the individual dose is not higher than 1 mSv / a. In the estimation process, all economic-related data are based on the data released by the National Bureau of Statistics and the estimated cost may be low.
