In Korea, July 2012, the law as called ‘Act on Safety Control of Radioactive Rays Around Living Environment’ wasimplemented to control the consumer product containing Naturally Occurring Radioactive Material (NORM), but, there are noappropriate database and effective dose calculation system. The aim of this study was to develop evaluation technique ofthe exposure dose with the use of the consumer products containing NORM and to understand the characteristics of theexposed dose according to the radiation type and energy. For the evaluate of exposure dose, the ICRP reference phantomwas simulated by the MCNPX code based on Monte Carlo method, and the minimum, medium, maximum energy of alphas,betas, gammas from the representative NORM of Uranium decay series were used as the source term in the simulation. Theannual effective doses were calculated by the exposure scenario of the consumer product usage time and position. Short rangeof the alpha and beta rays are mostly delivered the dose to the skin. On the other hand, the gamma rays mostly deliveredthe similar dose to all of the organs. The results of the annual effective dose with 1 Bq·g-1 radioactive stone-bed and 10%radioactive concentration were employed with the usage time of 7 hours 50 minute per day, the maximum annual effectivedose of alphas, betas, gammas were calculated 0.0222, 0.0836, 0.0101 mSv·y-1, respectively.
