방사성핵종의 대기방출로 인한 인근주민의 연간 집단선량을 대기확산모델과 USNRC에서 제안된 지상먹이연쇄모델을 결부시켜 AIRDOS-EPA전산코드를 사용하여 평가하였다. 평가결과는 전신의 경우, $3.348{ imes}10^{-1}manrem$으로 GASPAR전산코드에 의해 계산된 값과 다소 차이가 있었으나 갑상선의 경우, 84.95manrem으로 아주 낮게 평가되었다.
Annual collective dose within 50 miles radius of Ko-ri I reactor site due to normal airborne effluent discharges in 1979 has been estimated by AIRDOS-EPA computer code. Gaussian plume equation is used for estimation of both horizontal and vertical dispersion of radionuclide release into the atmosphere. Also, radionuclide concentrations in meat, milk, and fresh produce consumed by near-by population are estimated by coupling the output of the atmospheric transport models with the USNRC terrestrial food chain models. Annual collective doses are found to be $3.348{ imes}10^{-1}$ whole body manrem and 84.95 thyroid manrem. Whole body manrem calculated by AIRDOS-EPA computer code do not differ greatly from that calculated by GASPAR computer code, but value for thyroid manrem have been estimated lower than that calculated by GASPAR computer code.
