“…Adaptar las recomendaciones internacionales a la legislación nacional no ha sido una tarea fácil; la experiencia local es equiparable a la documentada en países europeos como Italia, donde se ha descrito que existe cierta complejidad y falta de coherencia en la legislación frente al manejo de residuos médicos radiactivos y que se debe hacer que los requisitos sean más sencillos, coherentes y eficaces (26).…”

“…Las divergencias de normativa entre países obedecen a su inclusión en el OIEA, pues todos los países que se acogen a sus recomendaciones han tenido que ajustar la legislación sobre los servicios de medicina nuclear y estos, a su vez, se han visto obligados a modificar sus protocolos, instalaciones y modelos de prestación para cumplir con la norma.

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.

“…The detailed progress of structure determination as subsequent peaks were found on difference Fourier functions and identified as extraframework atoms are presented in Table 3. The final weights were assigned using the formula w = 1/ [σ 2 (F o 2 ) + (aP) 2 + bP] where P = [max(F o 2 ,0) + 2F c 2 ]/3 and a and b are refined parameters. Their final values are given in Table 1.…”

“…Radioactive isotopes released from nuclear power plants (NPP) and medical applications are hazardous environmental pollutants. , In the last 30 years, the two large-scale NPP catastrophies have occurred at Fukushima and Chernobyl. After each of these two accidents, large amounts of highly radioactive elements such as 137 Cs, a common nuclear fission product, were released which affected not only the immediate environment but also more distant regions of the earth.…”

Smart materials that both sorb and announce the presence of radioactive isotopes such as 201Tl and 137Cs are needed for human safety in environmental catastrophies. This study reports progress toward zeolite-based self-luminous sensors for radioactive isotopes. Hf4+ was introduced into zeolite A by treating Tl-A and Cs,Na-A with HfCl4(g) under anhydrous conditions. The crystal structures of the products, Hf,Cl,Tl-A and Hf,Cl,Cs,Na-A, were determined by single-crystal crystallography using synchrotron X-radiation, with compositional confirmation by SEM-EDX analysis. Their luminescence properties upon X-ray, UV, and proton beam irradiation were studied. In Hf,Cl,Tl-A, some Hf4+ ions are 3-coordinate with three framework oxygen atoms of 6-rings; octahedral HfCl6 2– ions are at the very centers of 7% of the large cavities within Tl14HfCl6 12+ clusters. HfCl6 2– ions are also seen in Hf,Cl,Cs,Na-A; they similarly occupy 7% of the large cavities and are members of a Cs11HfCl6 9+ continuum. The X-ray-induced luminescence spectra of Hf,Cl,Tl-A and Hf,Cl,Cs,Na-A, and that of Hf,Cl,Tl-A induced by UV, are all broad bands from 300 to 720 nm, peaking near 400 nm. By comparisons with the corresponding spectra of Zr,Cl,Tl-A, Zr,Cl,Cs,Na-A, Cs2HfCl6, and Cs2ZrCl6, several luminescence mechanisms are proposed. These zeolite-based materials can be expected to emit light (be self-luminous) as radioactive isotopes exchange into them.

“…Como já exposto, o aumento das exposições não recai somente para pacientes submetidos aos procedimentos médicos, mas também para todos os envolvidos no procedimento, como por exemplo, familiares que acompanham o paciente, agentes de saúde (tecnólogos, médicos, físicos, enfermeiros etc) e o meio ambiente em geral. O meio ambiente é afetado devido à maior parte da atividade administrada ao paciente ser excretada diretamente no sistema de coleta pública de esgoto, que então, apesar de todo o tratamento, acabam por desaguar no meio ambiente [20,21] .…”

Patients undergoing Nuclear Medicine procedures, whether diagnostic or therapeutic, become radioactive sources for a period of time until the radioactive substance they incorporate is completely eliminated from their organisms. As a consequence, radioactive patients may expose other individuals and the environment to ionizing radiation. In order to reduce these exposures, radioprotective care with these patients is usually required. However, the small amount of radioactive material administered in diagnostic procedures leads to the question of the real need for such care and, even if this need is proven, it is still necessary to establish the period of its validity.There are no scientific studies in the literature to establish such care and its adequacy according to the clinical needs of each patient. Answers to these questions are linked to the true exposure potential these patients offer to other individuals, as well as the radiological risks arising from these exposures and radiation doses. Thus, this study primarily aims to evaluate these exposure potentials based on the study of patient-received radiopharmaceutical retention and excretion bikinetics, as well as to evaluate the radioprotective care to be implemented in diagnostic Nuclear Medicine either to reduce or control family exposures. and other individuals of the Society who may be exposed to these patients.
