title: Studying factors affecting the indoor gamma radiation dose using the MCNP5 simulation software.
abstract: Different factors and parameters affecting the indoor gamma radiation dose are considered and investigated. The change of the dose with different positions inside the room is discussed. The relative doses are also calculated for different changes; with different room dimensions, different wall thicknesses, and different building material densities. Some other factors are also discussed. The study is carried out by executing some models designed by the MCNP version 5 simulation software. The calculations of the dose rates are performed by adopting a simple and convenient calculation model which is based on the obtained relative changes of the dose rates with the different factors.
