In this research work we have investigated the pathways of nuclear radiation transferring to human via environment to establish a computational model to estimate its contaminant amount calculating the effective doses on environment as well as on human. For this, first we have independently considered three pathways of exposure- Airborne releases of radioactive air, Aqueous releases of radioactive water into watercourses and Aqueous releases of radioactive water into sewage. Finally, integrated them to estimate the overall hazard on environment. We have find out 14 ways to affect human. The governing equations are distribution functions. Classical Semi-infinite Cloud Model has used to solve the functions of external dose from radioactive plume. Monte-Carlo Method has applied only to solve the function of Gamma dose kernel integral over the plume. Here, we gave priority to make the air dispersion factor correct. The sample results has simulated for 1 year time span for both short term release and long term release of a normal operational Accelerator Facilities. Numbers of trials have been run to assume the approximate value to estimate the accurate results.
