Introducción. Colombia ha modificado las normas de medicina nuclear que impacta la administración de yodoterapia en el tratamiento de cáncer de tiroides. Objetivos. Identificar las áreas de acuerdo con respecto a la problemática, requerimientos presentes y emergentes asociados con la normativa para el funcionamiento de los servicios de medicina nuclear. Materiales y métodos. Se realizó un estudio Delphi de dos rondas para cada grupo de expertos, clínicos y regulatorios. La primera ronda exploró los puntos de vista sobre las implicaciones de la normativa que aplica a la medicina nuclear. La segunda ronda calificó por relevancia las declaraciones de la primera ronda. Resultados. La problemática de los servicios de medicina nuclear está relacionada con la claridad normativa y la falta de sinergia y coherencia entre los organismos de inspección, vigilancia y control. Las exigencias al sistema de gestión de desechos requieren una alta inversión económica que puede influir en la oferta del servicio y repercutir en el control integral del cáncer de tiroides. Entre las necesidades presentes y futuras se encuentran: unificación de criterios de los auditores, delimitación de funciones de los actuantes, asistencias técnicas a los servicios para cumplir con la normativa y la veeduría sobre los organismos de inspección, vigilancia y control por parte de los entes regulatorios. Conclusión. Los hallazgos de este estudio sugieren que los servicios de medicina nuclear atraviesan un momento de múltiples desafíos institucionales, normativos y económicos que ponen en riesgo el desarrollo y mantenimiento la medicina nuclear en la atención oncológica.

“…This can be done by discharging the patient directly if a diagnostic dose is administered, or after radioactively decaying in hospital waste storage tanks if the patient remains in hospital after therapeutic treatment [6]. Radionuclides applied in nuclear medicine and their transport in the sewage system have been the subject of many researches, sewage effluent and sludge activity concentrations in different WWTP were determined [7][8][9][10][11][12]. In these studies, many conclude that, once radionuclides have entered WWTP, some of them may associate and bind to organic particles settled during the water treatment process.…”

Driven by the current development of quantitative structure-properties relationship (QSPR) methods in the environmental science, we proposed an approach based on chemometric tools for selection of appropriate physicochemical parameters of radiopharmaceuticals residuals for predicting of partitioning, hazards and biodegradation of such compounds into the environment or into wastewater treatment plant. The present scheme was successfully applied for prediction of missing values for 24 different physicochemical and assessment response of the environmental fate descriptors for 11 tetrazine derivatives and 12 cyclooctene derivatives. The multivariate statistics was also proved to be useful in the evaluation of the obtained modelling results for identification of the ecological effect of radiopharmaceuticals residuals. The presented approach can be one of the first steps and support tools in the assessment of chemicals in terms of their environmental impact. The problem studies are significant since it allows a special point of view to the underestimated radiopharmaceutical pollutants.

“…Numerous studies have investigated their occurrences and geological relationships in the groundwater environments [1][2][3][4][5][6], as well as health risks via water ingestion [7][8][9]. Recent studies have begun to focus on the accumulation of NORMs in byproducts of the groundwater treatment process, such as sludge and sediments [10][11][12][13][14][15][16].…”

Groundwater contains naturally occurring radioactive materials (NORMs) through water–rock interactions. Although a recent study found that the NORMs are accumulated into the filters utilized in bottled mineral-water facilities, the accumulation mechanism and effects have rarely been studied. This study is, therefore, conducted to determine the mechanism of NORM accumulation in filters during water treatment processes and to provide a first estimate of the level of radiological risk for workers in five bottled-mineral-water facilities. The level of Rn-222 decreased dramatically at the first filters (FF) encountered after passing through water storage tanks, while surface radiation sharply increased. The increase of radioactivity on the FF was mainly caused by the accumulation of short-lived radon progenies through decay processes inside the water tanks. Although the estimated radiological risk was lower under certain circumstances compared to the public dose limit of 1 mSv yr−1, the radiological risk should be properly managed in case of direct and/or close handling of the used filters during filter replacement procedures.
