Summary
The article gives an overview on elaborated problems of the radiation protection of staff at the nuclear medicine department. In the introduction, there is presented the current number of PET scanners in the Czech Republic as well as geographically processed data on the total number of PET examinations at the workplaces of our country from 1999 to the 2014. In addition to the already eight existing institues there are another six new PET/CT scanners approved in the Czech Republic. The level of radiation protection at work when applied open radionuclide sources was already detected in abroad in many studies. In Poland they examined the influence of IR on DNA. In Ireland, they measured the dose to the eye lens by special dosimeter in order to compare the readings with the value of newly proposed limit for the eye lens of 20 mSv. In Spain they assessed various workflows and also other countries conducted optimization based on the studies. In the Czech Republic we held a retrospective study, especially in workplaces where there are beds for 131I therapy and there was an increase in processed annual activity, for example at 99mTc. ORAMED project, which took place within 32 European countries and was aimed at radionuklides 99mTc, 90Y and 18F. The result of the measurement of the exposed skin on hands at various locations was the recommendation to change the position of the finger dosimeter and to use a correction factor to calculate the dose on the skin of hand. It was found that the highest dose was measured at the tip of the index finger, while the finger dosimeter is worn at the base of the II., III. or IV. finger of more used hand. According to the recommendations, the calculation of the dose with using correction factor would come out from the measurements at the base index finger. This project also results in work that is focused on local irradiation of skin on workers’ hands at the departments of nuclear medicine in the country.
