Assessment of dose conversion coefficients for accident dosimetry with mobile phone components

Abstract

The resistors on the circuit board of a mobile phone can be used for accident dosimetry, because they exhibit optically stimulated luminescence due to radiation. The reconstructed dose from the resistors needs to be converted to organ absorbed doses. For this, Monte Carlo simulations are made. The resulting theoretical conversion coefficients are experimentally validated within this research. The main conclusion of this research is that the theoretical conversion coefficients do not significantly differ from the experimental conversion coefficients. However, during the dose reconstruction, various factors, such as fading and photon energy dependence can influence the reconstructed dose and introduce inaccuracies.
