“…Since skin exposure presents a special case as regards achieving compliance with the regulatory requirements, some more detailed measurements have been carried out in selected nuclear medicine clinics in the Czech Republic [7]. The measurements were carried out using special TLDs, the readings of which could be interpreted as the equivalent dose to the skin.…”

Abstract. During the manipulation with radiopharmaceuticals, workers in nuclear medicine always receive certain exposure which is continuously monitored and strictly controlled by relevant national regulatory authorities. This exposure should be minimized following the ALARA principle and be at all times below prescribed limits or reference levels. The paper presents some results of the assessment of radiation doses of nuclear medicine personnel where special attention is paid to the exposure of the extremities and to the skin of hands in particular. It has been observed that the skin dose of some workers may exceed the relevant annual dose limit and therefore some measures should be adopted to reduce this exposure. The situation in the Czech Republic related to the radiation burden of workers in nuclear medicine is outlined and conclusions discussed.

“…Twenty years ago, for the concerns raised by the radiation energy of the highly penetrating 511 keV annihilation photons, the first study of personnel dosimetry in positron emission tomography (PET) found that the effective radiation doses to technologists in PET centres (mostly carrying out 18 F-FDG studies) were within recommended occupational radiation protection guidelines [4], and since then, comparatively little attention has been paid to the problem of operator exposure.…”

“…In a study that used high-sensitivity TLD detectors placed on the fingertips of both hands and attached at the level of eye lenses and thyroid to assess equivalent doses to staff members, the highest dose was measured during the administration of 18 F-FDG to the patients and during the preparation of 18 F-FDG, the most exposed body parts being the tips of the thumb, index, and middle fingers [11]. The data from this study suggest that in a PET centre running 1500 18 F-FDG scans per year, and using approximately 200 MBq per patient, the annual occupational equivalent dose to the fingers due to the fractionation of the radiopharmaceutical in a dedicated hot cell would not exceed 100 mSv.…”

Radiation dose limitation in patients undergoing nuclear medicine procedures is accomplished through adherence to the principles of justification and optimization, while radiation doses to operators are controlled mainly by reducing exposure times, using shielding, and increasing the distance from the source. In both cases, however, a key role in dose management can also be played by innovative technologies, making this an important issue not only for nuclear medicine specialists, medical physicists, and technologists, but also for biomedical engineers and for industry [1][2][3]. 1Whereas the quest to achieve effective dose optimization for patients, in accordance with the ALARA principle, is currently the focus of intensive research and technological development activity, the need to develop and implement new devices to reduce operator exposure to ionizing radiation seems to be a secondary concern. Twenty years ago, for the concerns raised by the radiation energy of the highly penetrating 511 keV annihilation photons, the first study of personnel dosimetry in positron emission tomography (PET) found that the effective radiation doses to technologists in PET centres (mostly carrying out 18 F-FDG studies) were within recommended occupational radiation protection guidelines [4], and since then, comparatively little attention has been paid to the problem of operator exposure.However, in view of the now constantly increasing number of PET procedures being carried out in centres around the world, the use of positron emitters is becoming a real and a growing occupational concern. In this regard, it needs to be appreciated, in particular by those working in nuclear medicine on a day to day basis, that PET requires different radiation protection strategies from those usually adopted in general nuclear medicine, for reducing both the effective and equivalent dose to the extremities below the acceptable levels.Despite the use of routine precautionary measures, including the use of dedicated hot-cells, occupational doses in PET are higher than they need to be in order to obtain good quality examinations. The physical properties of positron emitting radiopharmaceuticals and the optimization of patient doses are both factors that, in addition to the greater number of PET studies now performed, can result in unnecessarily high occupational doses if adequate radiation protection operational procedures for working with positron emitting radionuclides are not envisaged, explained and rigorously adopted across all PET units, in accordance with local conditions.There are in fact three sources of exposure that contribute to the total personnel exposure for a given PET study, keeping in mind that their burden can be shared among different operators: indeed, exposure occurs during i) the patient undergoing the procedure, ii) the vial during the dispensing of the radiopharmaceutical, and iii) the syringe during the injection of the radiopharmaceutical. 1 The decay of positron emitters produces four times the amount of energy in photon...

The potential advantages and workflow challenges of long axial field of view PET/CT

Recently developed Long (≥100 cm) axial field of view (AFOV) PET/CT scanners are capable of producing images with higher signal‐to‐noise ratio, or performing faster whole‐body acquisitions, or scanning with lower radiation dose to the patient, compared with conventional PET/CT scanners. These benefits, which arise due to their substantially higher, by more than an order of magnitude, geometric efficiency, have been well described in the recent literature. The introduction of Long AFOV PET/CT technology into the clinic also has important implications for the design and workflow of PET/CT facilities and their effects on radiation exposure to staff and patients. Maximising the considerable benefits of this technology requires a thorough understanding of the relationships between these factors to optimise workflows while appropriately managing radiation exposure. This article reviews current knowledge on PET/CT facility design, workflows and their effects on radiation exposure, identifies gaps in the literature and discusses the challenges that need to be considered with the introduction of Long AFOV PET/CT into the clinic.
