Abstract:
It is important to determine the external dose due to the radiation emitted from building materials because individuals spend most of their time in their residence or office. In general, the radioactive isotopes 226Ra, 232Th, and 40K exist naturally in soil, rocks, and sand. When these materials are used in construction, the gamma radiation of natural radionuclides emitted from walls, floors, and ceilings could cause radiation exposure to humans. In this study, a room model with dimensions of 4m × 5m × 2.8 m and a wall thickness of 20 cm was built using the MCNP6 code. The simulation model was used to assess the external dose from the natural radioactivity of building materials in the human body. The absorbed dose from phantom water was calculated using a Monte Carlo simulation. Besides, a similar room model was performed with the RESRAD-BUILD code to compare the results obtained from the MCNP6 software.
Key words: external dose, absorbed dose, Monte Carlo, MCNP6, RESRAD-BUILD
