Radiological Risk Assessment of Vehicle Transport Accidents Associated with Consumer Products Containing Naturally Occurring Radioactive Materials

Natural and artificial ionizing radiation can be harmful to human health when they come into contact with people the environment. Transport of naturally occurring radioactive materials (NORMs) consumer products containing NORM in public domain is inevitable owing their potential applications. This study evaluates dose risk from transport accidents products. Radiological physical data were obtained previous literature. The median maximum values radioactivity concentration applied data, which serve as an input. An external rate at 1 m a transported shipment was calculated using Microshield® Pro version 12.11 code, serves input RADTRAN 6 code. Based on developed accident scenarios, code used estimate collective risk. sensitivity analysis conducted by considering variation release, aerosol, respirable fractions radionuclides 0.1%, 1%, 10%, 100% during accident, respectively. results general because damage container following fire are below annual regulatory limits man-Sv recommended IAEA regulation 2018. all NORMs associated also limits. Therefore, radiological safety ensured event involving transit NORM.
