“…During the same years, doses in our sample were higher than estimates of effective doses for general medical workers worldwide (mean, 0.7 mSv in 2000-2002) (19) and in the U.S. (mean, 0.74 mSv in 2003 and 0.75 mSv in 2006) (22) and were higher than the effective doses estimated in the U.S. Radiologic Technologists Study (21). Annual doses in our U.S. sample were consistent with published values of effective doses for NM technologists in other countries (19), including Bosnia and Herzegovina (12), Portugal (13), Lithuania (14), Greece (15), and Costa Rica (16), which generally ranged from 1.5 to 3.5 mSv.…”

“…In total, nine institutions agreed to participate and provided the requested information by the requested deadline. The most common reasons given for not being able to supply information were the unavailability of clerical resources to identify the NM (12)(13)(14)(15)(16)(17)(18). Much of this evidence was summarized by the United Nations Scientific Committee on the Effects of Atomic Radiation report, entitled Global Survey of Occupational Radiation Exposures (19).…”

Purpose To summarize occupational badge doses recorded for a sample of U.S. nuclear medicine technologists. Materials and Methods Nine large U.S. medical institutions identified 208 former and current nuclear medicine technologists certified after 1979 and linked these individuals to historic badge dose records maintained by a commercial dosimetry company (Landauer), yielding a total of 2618 annual dose records. The distributions of annual and cumulative occupational doses were described by using summary statistics. Results Between 1992 and 2015, the median annual personal dose equivalent per nuclear medicine technologist was 2.18 mSv (interquartile range [IQR], 1.25-3.47 mSv; mean, 2.69 mSv). Median annual personal dose equivalents remained relatively constant over this period (range, 1.40-3.30 mSv), while maximum values generally increased over time (from 8.00 mSv in 1992 to 13.9 mSv in 2015). The median cumulative personal dose equivalent was 32.9 mSv (IQR, 18.1-65.5 mSv; mean, 51.4 mSv) for 45 technologists who had complete information and remained employed through 2015. Conclusion Occupational radiation doses were well below the established occupational limits and were consistent with those observed for nuclear medicine technologists worldwide and were greater than those observed for nuclear and general medical workers in the United States These results should be informative for radiation monitoring and safety efforts in nuclear medicine departments.

“…One exception is Greece, which introduced fixed dose constraints for the medical sector in 2005, including the different occupational groups and various departments (Kamenopoulou et al, 2001). For all workers in departments of nuclear medicine and radiology in Greece, the dose constraint was set at 2 mSv/year.…”

The practical considerations of dose constraints in diagnostic medical departments using ionizing radiation

et al. 2013

-The term "dose constraint" has been used in radiological protection since 1990. Its practical application has varied from country to country to the present day. The authors of this paper believe that it is an underestimated tool for the purpose of radiological protection. This study aims to estimate local dose constraints for workers in conventional nuclear medicine and radiology departments, on the basis of doses received in the last 3 to 4 years by different groups of workers. The levels of exposure to employees of the nuclear medicine department correspond well to levels in other countries, but for employees belonging to the radiology department, the levels are significantly lower. Unification of the practical application of dose constraints and legislation concerning their specific values would increase the relevance and effectiveness of these operational units. This is a playing field for radiation safety officers for the determination and widespread publication of local dose constraints in their particular medical departments.

OBJETIVO: Avaliar a dose efetiva recebida pelos trabalhadores envolvidos na realização de procedimentos de hemodinâmica, de forma a estabelecer parâmetros comparativos entre os dados obtidos com uma câmara de ionização e pelos dosímetros usados para monitoração individual. MATERIAIS E MÉTODOS: A avaliação foi desenvolvida em um serviço de hemodinâmica, sendo que os testes constaram da medida do taxa de kerma no ar no ambiente real de trabalho, na posição ocupada por médicos e enfermeiros, com e sem a utilização de barreira plumbífera de proteção. Foi levado em consideração o número de exames realizados no serviço e foram selecionados as projeções e parâmetros radiográficos mais utilizados. Para a estimativa da dose efetiva foram utilizados fatores de conversão encontrados na literatura. RESULTADOS: Os valores encontrados em dose efetiva e de dosimetria são consistentes. Observou-se, ainda, que o uso da barreira protetora plumbífera reduz em até 97% a dose recebida pelo profissional, devendo esta ser utilizada na rotina de exames. CONCLUSÃO: Os valores apresentados são representativos, não podendo ser assumidos como reprodução das condições de monitoração individual, mas são válidos para comparações e orientação na otimização das doses.
