The dose limit for the skin of the hand is typically converted to a surface of 1 cm2, which means that one needs to measure point doses in different places on the hand. However, the commonly used method of measuring doses on the hand, i.e., using a dosimetric ring including one or several thermoluminescent detectors worn at the base of a finger, is not adequate for manual procedures such as labeling or radiopharmaceutical injection. Consequently, the purpose of this study was to create and conduct a series of computer simulations that, by recreating the actual working conditions, would provide information on the values of ionizing radiation doses received by the most exposed parts of the hands of employees of radiopharmaceutical production facilities, as well as those of nurses during the injection of radiopharmaceuticals. The simulations were carried out using Monte Carlo radiation transport calculations. The Hp(0.07) personal dose equivalent values obtained for the fingertips of the index and middle fingers of nursing staff and chemists were within the range limited by the minimum and maximum Hp(0.07) values obtained as a result of dosimetric measurements carried out in diagnostic and production centers. Only in the case of the nurse’s fingertip, the simulated value of Hp(0.07 slightly exceeded the measured maximum Hp(0.07) value. The comparison of measured and simulated dose values showed that the largest differences in Hp(0.07) values occurred at the thumb tip, and for ring finger and middle finger of some of the nurses investigated.

在处理18F-FDG时使用Monte Carlo方法评估Hp(0.07)值。

手部皮肤的剂量极限通常转换为1 cm 2的表面,这意味着需要在手的不同位置测量点剂量。然而,常用的测量手部剂量的方法,即使用包括戴在手指根部的一个或几个热致发光检测器的剂量环,不足以进行手动操作,如标记或放射性药物注射。因此,本研究的目的是创建并进行一系列计算机模拟,通过重新创建实际的工作条件,将提供有关放射性药物生产员工手中最暴露的部分收到的电离辐射剂量值的信息。设施以及注射放射性药物期间的护士设施。使用蒙特卡洛辐射输运计算进行了模拟。的ħ p(0.07)个人剂量当量为索引的指尖和护理人员和化学家的中指得到的值是由最小和最大限制的范围内ħ p作为剂量测定测量的结果而获得(0.07)值进行诊断和生产中心。仅在护士的指尖的情况下,的模拟值ħ p(0.07稍微超过所测量的最大ħ p(0.07)值。的测量的比较和模拟剂量表明,在最大差异值ħ p(发生0.07)值在拇指尖和无名指和中指的一些护士中进行了调查。
