由于放射性人体剂量是通过食物链和暴露途径计算的，因此进行途径分析以确定所有途径的贡献对于进一步的放射性环境风险评估非常重要。污染物归宿和环境路径分析的一个挑战是处理大量的环境组分，并为相关组分对分配适当的计算模型。本文提出了一个模型模板，称为传输路径模型模板（TPMT），存储传输模型的环境类对。当建立特定于站点的计算方案时，由方案定义源-受体转移矩阵（SRTM）。然后，计算循环通过SRTM中的所有源-受体组件对，并应用存储在TPMT中的适当模型来计算传递因子。TPMT可用作组件路径验证模板和模型分配模板。这种结构被用于环境风险评估（ERA）应用程序，称为IMPACT，已被应用于加拿大的一些核电厂和铀矿。
As radioactive human doses are calculated through food chain and exposure pathways, it is important to take a pathway analysis to determine all pathway contributions for further radiological environmental risk assessment. A challenge of contaminant fate and environmental pathway analysis is to handle a large number of environmental components and to assign proper calculation models to linked component pairs. This paper presents a model template called transfer pathway model template (TPMT) that stores transfer models to environmental class pairs. When a site-specific calculation scenario is built, a source–receptor transfer matrix (SRTM) is defined by the scenario. Then the calculation loops through all source–receptor component pairs in SRTM and apply proper models stored in TPMT to calculate the transfer factors. TPMT can be used as the component pathway verification template and model allocation template. This structure is used in an environmental risk assessment (ERA) application called IMPACT that has been applied for a number of nuclear power plants and uranium mines in Canada.
