The assessment of the absorbed dose of radiation around a nuclear fuel manufacturing plant
The estimation of the absorbed dose of radiation by the public around a nuclear plant is a substantial issue for nuclear industries and serves as an essential factor in radiation protection. In this study, the absorbed dose of radiation by the individuals living around a nuclear fuel manufacturing plant was calculated. The Atomic Force Microscopy (AFM) code, which is the generalised version of the AIREM program manual – a computer code for calculating doses, population doses, and ground depositions due to atmospheric emissions of radionuclides – was used to investigate the following pathways: cloud immersion, ground deposition, inhalation and ingestion. The study was carried out in 16 geographical directions over an 80 km radius. The experimental results demonstrate that the maximum dose is absorbed at 800 m distance from the nuclear plant stack in the east southeast (ESE) direction and is equal to 3.7 × 10³ μSv, which is negligible in comparison with the background radiation.
