“…Recently, the treatment of neuroendocrine tumours with radioactive peptides (PRRT) has been increasingly applied. The most common radiopharmaceuticals for PRRT are somatostatin analogues labelled with 90 Y and especially 177 Lu [16,61,63]. With 47 500 treatments in the USA in 2018, 177 Lu-PSMA is increasingly being used for the treatment of patients with PSMApositive metastatic castration-resistant prostate cancer [64].…”

The exposure of the fingers is one of the major radiation protection concerns in nuclear medicine (NM). The purpose of this paper is to provide an overview of the exposure, dosimetry and protection of the extremities in NM. A wide range of reported finger doses were found in the literature. Historically, the highest finger doses are found at the fingertip in the preparation and dispensing of 18F for diagnostic procedures and 90Y for therapeutic procedures. Doses can be significantly reduced by following recommendations on source shielding, increasing distance and training. Additionally, important trends contributing to a lower dose to the fingers are the use of automated procedures (especially for positron emission tomography (PET)) and the use of prefilled syringes. On the other hand, the workload of PET procedures has substantially increased during the last ten years. In many cases, the accuracy of dose assessment is limited by the location of the dosimeter at the base of the finger and the maximum dose at the fingertip is underestimated (typical dose ratios between 1.4 and 7). It should also be noted that not all dosimeters are sensitive to low-energy beta particles and there is a risk for underestimation of the finger dose when the detector or its filter is too thick. While substantial information has been published on the most common procedures (using 99mTc, 18F and 90Y), less information is available for more recent applications, such as the use of 68Ga for PET imaging. Also, there is a need for continuous awareness with respect to contamination of the fingers, as this factor can contribute substantially to the finger dose.

“…The use of the appropriate dosimeter is essential when dealing with mixed radiation fields such as those from 68 Ga. Studies have found a clear correlation between the dosimeters filter and detector thickness and response to beta particles. Carnicer et al [24] recommended that thin TLDs (<10 mg cm −2 ) should be used when positrons or electrons contribute significantly to the H p (0.07), otherwise underestimations up to 50% are possible. In a recent publication investigating specifically the response of a range of TLD types to 68 Ga, Van Hoey et al [25] found that MCP-Ns TLDs (8.5 mg cm −2 ) provided the best response, while MCP-N (225 mg cm −2 ) and MTS-N (225 mg cm −2 ) TLDs showed about 20% under-response when used for monitoring an unshielded syringe.…”

Finger doses due to ⁶⁸Ga-labelled pharmaceuticals in PET departments—results of a multi-centre pilot study

Introduction: Although the use of 68Ga has increased substantially in nuclear medicine over the last decade, there is limited information available on occupational exposure due to 68Ga. The purpose of this study is to determine the occupational extremity exposure during the preparation, dispensing and administration of 68Ga-labelled radiopharmaceuticals. Method: Workers in eight centres wore a ring dosimeter for all tasks involving 68Ga-labelled radiopharmaceuticals for a minimum of one month. Additionally, the fingertip dose was monitored in two centres and the hand with the highest ring dose during 68Ga procedures was also identified in one centre. Results: The median normalised ring dose for 68Ga procedures was found to be 0.25 mSv.GBq−1 (range 0.01 – 3.34). The normalised 68Ga ring doses recorded in this study are similar to that found in the literature for 18F. This study is consistent with previous findings that the highest extremity dose is found on the non-dominant hand. A limited sub study in two of the centres showed a median fingertip to base of the finger dose ratio of 4.3. Based on this median ratio, the extrapolated annual 68Ga fingertip dose for 94% of the workers monitored in this study would be below Category B dose limit (150 mSv) and no worker would exceed Category A dose limit (500 mSv). Conclusion: When appropriate shielding and radiation protection practices are employed, the extremity dose due to 68Ga is comparable to that of 18F and is expected to be well below the regulatory limits for the majority of workers.
