Abstract :

Urban populations in Morocco receive free medical drugs as prescribed by doctors in district health centres. To explore the exposure pathway of 238U, 232Th and their decay products to the skin of patients, these radionuclides were measured in various medical drugs by using solid state nuclear track detectors (SSNTDs).The measured concentrations range of 238U and 232Th in the medical drug samples of interest vary from (4.3�±0.3) mBq l-1 to (11.1�±0.7) mBql-1 and (0.49�±0.03) mBql-1 to (1.3�±0.1) mBql-1, respectively. A new dosimetric model, based on the concept of specific alpha-dose and alpha-particle residual energy, was developed for evaluatingradiation doses to skinfollowing the applicationof different medical drugs by patients. The maximum total equivalent effective dose to skin due to the 238Uand 232Th series from cutaneous application of different medical drugs by patients was found to be 2.8 mSv y-1cm-2.
