“…The critical importance of cocktail matching, particularly for tracing low-energy β emitters like 63 Ni, has been treated by Collé [35]. The methodology has been described in numerous publications by Coursey et al [16, 34, 36, 37]. Details on its practical application, as recently invoked for 63 Ni and considered here, are given by Collé and Zimmerman [1, 18], by Zimmerman and Collé [23, 24], and by Collé [35].…”

“…This xylene-based scintillant was chosen to examine possible differences in the efficiency tracing that might result from its use compared to the use of the newer “environmentally safe” (i.e., non-toxic, non-flammable, and bio-degradable) scintillants like UG. Most of the initial development work on the CIEMAT/NIST tracing method was performed with very stable cocktails that used the older, “environmentally unsafe” scintillants [16, 34, 36, 37]. …”

The National Institute of Standards and Technology recently participated in an international measurement intercomparison for 63Ni and 55Fe, which was conducted amongst principal national radionuclidic metrology laboratories. The intercomparison was sponsored by EUROMET, and was primarily intended to evaluate the capabilities of liquid scintillation (LS) spectrometry techniques for standardizing nuclides that decay by low-energy β-emission (like 63Ni) and by low-Z (atomic number) electron capture (like 55Fe). The intercomparison findings exhibit a very good agreement for 63Ni amongst the various participating laboratories, including that for NIST, which suggests that the presently invoked LS methodologies are very capable of providing internationally-compatible standardizations for low-energy β-emitters. The results for 55Fe are in considerably poorer agreement, and demonstrated the existence of several unresolved problems. It has thus become apparent that there is a need for the various international laboratories to conduct rigorous, systematic evaluations of their LS capabilities in assaying radionuclides that decay by low-Z electron capture.

“…Our "best" recommended absolute γ-ray emission probabilities are mainly from weighted averages of all measurements except Goswamy [8] and Coursey [9]'s measurements. The evaluated uncertainties are the greatest of the internal or external uncertainties and expanded to cover the most precise input value.…”

IAEA), World Health Organization (WHO) and European Association of Nuclear Medicine (EANM). The attributes of the components in the quality system (QA/QC), including organization, staffing and personnel, facilities, instrumentation and equipment, operation procedure, radiopharmaceuticals, protocol and conduct of a study or a treatment, records and reports, and audit framework were further characterized. Assessments and comparisons of critical quality attributes (CQAs) for assuring accurate radioactive dosimetry calculation in the efficiency tracing of absolute activity measurement and patient-and technologistrelated risks for nuclear medicine imaging including Positron Emission Tomography (PET), Computed Tomography (CT), PET/CT, and Single Photon Emission Computed Tomography (SPECT) were identified. Quality system design based on the Requirements and Guidelines Quality policy and systemThe quality system by design for radiopharmaceuticals and clinical imaging techniques is aimed to maintain and improve the qualified service for the patients, fulfill the regulatory requirements, optimize the safety and efficacy for patient care, demonstrate a proper equipment operating condition, and obtain a reliable quantitative performance in both diagnostic and therapeutic nuclear medicine procedures [4,5]. The pursuit of excellence in quality system is not a single action over a short period, instead, it is achieved through the whole life cycle of instruments, analytical methods or education for example, from planning and procurement to decommissioning based on advanced technology [6]. Continuous quality improvement implies a commitment to continuously struggle to advance based on state-ofthe-art information and techniques developed by the nuclear medicine and metrology community at large [5].Implementation of a quality system must be in accordance with the quality police, i.e. the overall quality intentions and direction of an organization, as formally expressed by top management. And quality system includes the structure, responsibilities, and procedures for implementing quality management. An integrated infrastructure of quality policy and system design is demonstrated as in Figure 1, which is mainly developed from the European Standard EN 28402 proposed by Bergmann et al. [7]. The attributes of the components in the quality sub-system (QA/QC), e.g. organization, personnel, facilities, instrumentation, operation procedures, preparation of radiopharmaceuticals, protocol and conduct, records and reports, and audit or inspection, were further integrated and classified in this article.
