Improving the reliability of the assessment of the skin exposure of the hands of workers handling selected radiopharmaceuticals based on the correction of finger dosimeter readings

Original language description

Nuclear medicine departments using 18F and 68Ga labelled radiopharmaceuticals participated in this pilot study. TLDs were used to assess personal dose equivalent Hp(0.07). The measured maximum exposure of each worker was related to the activity being manipulated. Subsequently, the average values of selected groups of workers engaged in radiopharmaceutical labelling, filling into syringes and applications have been applied to establish relevant correction factors for each monitored workplace. The paper presents a summary of the comparison of results from finger dosimeters in selected occupational groups in the period of 2009 - 2019 and highlights new findings regarding the correction factor for selected radiopharmaceuticals over the last decade. In addition, the pilot experiments with 68Ga are discussed in terms of the average exposure of the skin of the hand in the position at the tip of the index finger of the workers. The paper illustrates the cases of manipulation with 68Ga-labelled radiopharmaceuticals, which resulted in the significantly higher exposure of the skin. A more detailed monitoring of the radiation exposure of the skin on more locations on the workers’ hand can reveal cases of abnormal working operations or elevated local exposure which is often found on the fingertips.
