摘要
Monte Carlo simulations are exploited to assess the annual radiation doses from some cosmetics due to the radioactive decay series of U-238 and Th-232 and to the radionuclide K-40. The measured radioactivity concentrations are entered into simulation codes modeled and implemented by Monte Carlo n-particle software. The concentrations are found to be relatively high for a large number of the samples. The Monte Carlo-simulated gamma-radiation annual doses are compared with the results of another theoretical approach. Both methods are in good agreement with each other and predict low doses from use of cosmetics.
