考虑到未来引入ICRP 60的立法，对放射性药物的操作程序进行了审查，目的是减少肢体辐射剂量。放射性药剂师的指尖剂量指数使用TLD测量。放射性药剂师右（非惯用手）食指接受的平均剂量为0.7 mSv/10 GBq，左（惯用手）食指接受的平均剂量为0.2 mSv/10 GBq。这些剂量与其他出版物相当。放射性药剂师在制备99 Tc（m）-MDP期间接受的辐射剂量最大。在该制备过程中，将盐水抽入已经含有99 Tc（m）-锝的注射器中，这导致手指的剂量。改变了技术，以便将盐水和99 Tc（m）-氚分别取出并注射到MDP套件中。这将右手指的辐射剂量降低到每10 GBq 0.4 mSv，而左手指的辐射剂量保持在每10 GBq 0.2 mSv。这表明，通过简单的程序改变，可以有效地减少辐射剂量。
With the future introduction of legislation originating from ICRP60 in mind, the operating procedures for the radiopharmacy were reviewed, with the intention of reducing extremity radiation dose. The radiopharmacist's index fingertip dose was measured using TLDs. The radiopharmacist received a mean dose of 0.7 mSv per 10 GBq of administered activity for the right (non-dominant hand) index finger and 0.2 mSv per 10 GBq for the left (dominant hand) index finger. These doses were comparable with other publications. The radiopharmacist received the largest part of the radiation dose during the preparation of 99Tc(m)-MDP. During this preparation, the saline was withdrawn into a syringe already containing 99Tc(m)-eluate, which results in a dose to the fingers. The technique was changed so that the saline and 99Tc(m)-eluate were withdrawn and injected separately into a MDP kit. This reduced the right finger radiation dose to 0.4 mSv per 10 GBq, while the left finger radiation dose remained at 0.2 mSv per 10 GBq. This shows that radiation doses can be effectively reduced using simple changes in procedure.
