Monte carlo calculation for radiation dose prediction easily predicting monte carlo method for indoor radiation dose (part i)

This paper deals with a novel method of calculating radiation dose rate within a building and around its surroundings. We employed the Monte Carlo method to calculate the direct gamma rays absorbed in an object. The buildup fluxes caused by the Compton scattering were simply treated with the buildup factor as a function of the mean free path of photons. The proposed method was benchmarked for a simplified geometry case and compared with the point-kernel integration code QAD-CGGP-A. The results of both methods were in good agreement. The proposed method could be used for predicting radiation dose rate in the fission products deposited areas.
