“…É um polímero reticulado que forma uma estrutura de rede tridimensional. Esta rede tridimensional retém água dentro da sua estrutura, tornando-a altamente hidratada e capaz de absorver e reter grandes quantidades de líquido, muitas vezes em quantidades muito superiores ao seu próprio peso (Alonso, 2018).…”

“…Additionally, there is a peripheral pneumatic transfer system that was part of the original design (1965) and is used to irradiate samples in a position adjacent to the core (Position A6). This old system was used from 1968 to 1992 for radioisotope production ( 24 Na, 32 P, 82 Br, 198 Au and 99 Mo) [17].…”

This chapter describes recent advances of the Colombian Neutron Activation Analysis Laboratory (CNAAL) within the framework of expansion of geoscientific and nuclear knowledge in Colombia. Having the necessary historical references as a pillar of the current developments, the authors initially describe technical facilities of the laboratory and then articulate in an integral way of the value chain of this singular scientific and technological installation of Colombia. Its different stages beginning with the preparation of the samples, its irradiation process by different systems, recent novelty of the development of an "automated system of positioning of samples for gamma spectrometry," analysis of gamma spectra to obtain concentration data of chemical elements, management of the radioactive waste generated, analytical quality control of the data obtained and finalizing in the use of this data to cover selected topics of knowledge in strategic sectors of our country's development like a sustainable exploitation of mineral and hydrocarbons resources, researches in environmental and forensic sciences, technical developments in nuclear sciences, all aimed at improving the quality of life of Colombian citizens.

“…La razón principal que justifica el uso de radiación ionizante como tratamiento de alimentos es la misma que justifica cualquier otro uso con fuentes radiactivas: un ahorro significativo de tiempo y la disminución de esfuerzo [8]; adicionalmente, encontramos que la relación de costo-beneficio es considerablemente mayor en comparación con otras tecnologías de conservación [9]. Diversos autores coinciden en que son más los beneficios que los perjuicios implicados en el tratamiento correcto de alimentos con radiación gamma [9], [10].…”

La irradiación gamma es un método seguro y efectivo de control de microorganismos dañinosy patógenos en diferentes clases de productos que los humanos consumen en todo elmundo, sean alimentos o productos de farmacia, cosmética y dispositivos médicos. La irradiacióngamma de alimentos se utiliza principalmente con el fin de lograr su preservaciónmediante la reducción del deterioro, el mejoramiento de su higiene y el aumento de su vidaútil. Son varias las aplicaciones en la industria alimentaria, que van desde desinfestaciónde frutas y semillas, inhibición de brotes en tubérculos, conservación y desinfección, hastaesterilización, de todas las cuales derivan múltiples beneficios; cada una suple una necesidadque otras tecnologías no satisfacen totalmente, lo cual genera un menor impacto económicoy ambiental. A pesar de su importante aporte a la preservación e inocuidad de los alimentos,en el ámbito nacional no se aplica la tecnología de irradiación en las cadenas de produccióny se desconocen los efectos específicos de la técnica sobre la calidad de los productos locales,así como las características inherentes de posibles productos irradiados que entran al país,a lo cual se suma una desconsiderada falta de regulación que respalde su explotación segura.
