Abstract: This research introduces the background, model’s structure and parameters of the National Council on Radiation Protection and Measurements’ (NCRP) No.156 Report’s Wound Model. By connecting the NCRP Wound Model with the current newest System Model(ICRP No.141 Publication) and Human Alimentary Tract Model (ICRP No.100 Publication), the retention and excretion fractions for wound intake are calculated. After testing the correctness of the program of this research of the Wound model with data in reference, the Wound model is connected with the already correct System Model and HATM. Then the retention fractions changing with time in Wound site, Lymph nodes, Liver, Skeleton, daily urine and faeces excretion fractions after wound intakes of different kinds ²⁴¹Am are calculated, which gives support for the intake evaluation for accidental wound intake of ²⁴¹Am .

Key words: wound model, retention fractions, excretion fractions, Am
