Difficulties in achieving compliance with the dose limit requirements for the skin exposure of workers handling radiopharmaceuticals

Popis výsledku v původním jazyce

Our measurements were carried out at nuclear medicine departments applying radiopharmaceuticals. The readings of these dosimeters were compared with the personal equivalent dose Hskin(0.07) corresponding to the location showing the maximum exposure. The results of the correction factors was found to be in the range of 2-6 depending on the individual radionuclide handled and also on the worker´s specific routine adopted in manipulating radiopharmaceuticals. In the case of 131I, 11C and 18F, the mean value of this factor amounted to 2, 2.8 and 3.5, respectively. The highest value was observed for 68Ga being close to 6. Our previous studies as well as the results presented by other authors indicate that nearly one in five workers in nuclear medicine might exceed the legal dose limit for skin. This is why it is important to pay attention to adopting a reliable approach to monitor the equivalent skin dose consistent with the definition of the relevant quantity. Since in most cases, the dosimeter is not located at the position with the maximum exposure, the use of the appropriate correction factor is the only way to ensure that the readings of routine dosimeters can be interpreted in terms of the equivalent skin dose.
