描述了一个新近建立与开发的能预测核事故后果的动态食物链模式与程序。它既适用于西方饮食谱，也适用于中国居民的饮食谱。此模式考虑了干、湿沉积截获和初始滞留、易位、入渗、根部吸收、耕作等过程对事故释放导致的植物可食部位中核素浓度的影响。也考虑了动物对核素的摄入、食品加工的影响及人体食入途径对核素的摄入率。在干沉积中考虑了有效叶面积指数对干沉积量的影响，在湿沉积中考虑了事故期间不同时段不同降雨强度对湿沉积量的贡献的计算方法。程序由１个主程序和５个子程序组成，分别计算植物与土壤表面的干、湿沉积量；核素在植物中的易位，植物可食部分及动物产品中的核素浓度及人体的摄入量等。
Describes a newly established and developed dynamic food chain model and procedures that predict the consequences of a nuclear accident. It applies to both Western diet recipes, but also applies to Chinese residents diet recipes. This model considers the effect of dry and wet deposition interception and initial retention, translocation, infiltration, root absorption and tillage on the nuclide concentration in plant edible parts caused by accident release. Consideration has also been given to animal intake of nuclides, the effects of food processing and the rate of uptake of nuclides by human ingestion routes. In the dry deposition, the effect of effective leaf area index on the dry deposition was taken into account, and the calculation method of the contribution of different rainfall intensities to the wet deposition at different periods during the accident was considered in the wet deposition. Program consists of a main program and five subroutines, respectively, the calculation of plant and soil surface dry and wet deposition; nuclide translocation in plants, plant edible parts and animal products in the nuclide concentration and the human body’s photo Into the volume and so on.
