Simple Empirical Expression to Evaluate Effective Dose Equivalent for External Photon Irradiation

For the estimation of external photon exposure, it is important to assess the dose equivalent in organs or tissues HT and the effective dose equivalent HE while the accuracy required will depend on the use of the data(1). As the quantities of the dose limits are not measured directly, conversion coe...

Summary:For the estimation of external photon exposure, it is important to assess the dose equivalent in organs or tissues HT and the effective dose equivalent HE while the accuracy required will depend on the use of the data(1). As the quantities of the dose limits are not measured directly, conversion coefficients that link dosimetric and radiation protection quantities are necessary to estimate them. Two approaches to determine the conversion coefficients, computational and experimental, have mainly been used, but an evaluation of these is not a trivial matter.
