Optimization of the exposure to workers handling of radiopharmaceuticals
Original language description
The ORAMED studies found a direct relationship between the total distribution of the personal dose equivalent Hp(0.07) characterizing skin exposure. In case of overexposure the dose distribution of workers is visibly distorted. By comparing the analysis of this distribution using the multiple linear regression with a similar analysis of a worker normally exposed under the same radiopharmaceutical manipulation procedures, it is possible to identify possible reasons causing excessive exposure. The dose distribution matrix have been determined by the measurement on a physical phantom in combination MCNP5 code and a voxel hand phantom. Ten TLDs positioned on gloves were used to map the overall dose distribution during the administration. The method of identifying the operations or procedures causing excessive exposure was used for the investigation of two overexposed workers. The matrix of the mean hand dose distribution was determined by measuring on the physical hand phantom in combination with Monte Carlo code calculations (MCNP5) using a hand voxel phantom. The most serious procedures behind the excessive skin exposure was attributed to the non-reported administration of FDG to patients by unshielded syringe while in the second case, the overexposure was caused by the undetected surface contamination of the hands.
