“…The results reported by Siddeeg, et al, (2014), and Sethy, et al, (2011), on 226 Ra concentrations in sediments of rivers that are considered affected by mining activity, are in a range between 15. 0 and 179.0 Bq/kg, while in the works of Sethy, et al, (2011) and Rowan, et al, (2013) in rivers not affected by mining activity, concentrations of 226 Ra in the sediments are between 1.99 Bq/kg and 4.50 Bq/kg; these last values are comparable with those obtained in this work, which were between 0.90 ± 0.07 Bq/kg and 1.30 ± 0.08 Bq/kg for the Irquis River, and 1.10 ± 0.08 Bq/kg and 19.30 ± 0.08 Bq/kg for the Portete River.…”

Mineral processing has been identified among the twelve main industrial processes that must be under control due to the expose to natural radioactive sources. The modification and, generally, the increase in the concentration of Naturally Occurring Radioactive Materials (NORM) in the earth's crust cause an imbalance in the ecosystem. Imbalance that affects the fauna, which are able to bio accumulate these radioisotopes and introduce them into the trophic chain. The main purpose of this work was to establish a radio-ecological baseline. For this purpose, the concentration levels of 226Ra in rainbow trout, in macro invertebrate matrices-substrates and water from the Irquis and Portete rivers were evaluated. A study area adjacent to the Loma Larga mining concession was selected. The measurements were made using the Lucas cells coupled to a Pylon AB6A counter and the "Can Technique", using LR-115 passive detectors. The results indicated that rainbow trout bio accumulated in bones and organsa mean of 94.7% of the total 226Ra detected, which values varied from 4.69 to 2.46 Bq/kg, while macro invertebrate-substrate matrices showed a concentration that ranged between 0.7 and 1.3 Bq/kg in the Irquis River, while in the Portete River was between 1.1 and 19.3 Bq/kg. The water samples, in the sampling points of the Irquis River, showed concentrations that ranged between 37.3 and 119.1 mBq/l and in the Portete River between 43.5 to 146.4 mBq/l.

“…Long term exposure to chemicals such as pesticides, uranium [21], nickel, asbestos, radon and benzene can increase the risk of cancer. Such carcinogens may act alone or in combination with another carcinogen, such as cigarette smoke, to increase the risk of cancer and other lung diseases [22].…”

Reactive oxygen species are constantly produced in our body due to various factors like environmental pollution, unhealthy diet habits, cellular metabolism etc. Epidemiological studies suggest that the intakes of antioxidants are inversely related to the cancer risk. While the cell culture studies confirm the effect of antioxidants against cancer, the clinical trials remains inconclusive. The human population is heterogeneous regarding Reactive oxygen species (ROS), so screening the human population for developing the risk of cancer will provide a scientific ground for the application of antioxidants. Research is increasingly showing that those who eat antioxidant-rich foods reap health benefits. Foods, rather than supplements, may boost antioxidant levels because foods contain an unmatchable array of antioxidant substances.

“…Sin embargo, las escombreras con los desechos de la minería permanecen sin alterar y por tanto en pleno contacto con el medio ambiente con la consecuente migración y paso a la cadena trófica. La peligrosidad de estos desechos habitualmente se evalúa mediante la determinación de la transferencia de los radionucleidos al medio acuático (Liu et al, 2017;Sethy et al, 2011;Tricca et al, 2000) y su fraccionamiento (Štrok and Smodiš, 2010).…”

La determinación de las concentraciones de actividad de los diferentes radionucleidos en las áreas abandonadas de la minería de uranio es necesaria para conocer los niveles de radiación y a partir de ellos, decidir si es o no necesaria su rehabilitación. En este trabajo se ha establecido una metodología que permita conocer el verdadero impacto radiológico ambiental a partir de las concentraciones de actividad de diferentes grupos de emisores gamma pertenecientes a las series radiactivas naturales del 238 U, 235 U y 232 Th. Los valores obtenidos han permitido comprobar la dispersión de la contaminación en función de la rosa de los vientos así como la zona que supone un riesgo radiológico importante. El factor más influyente en la zona estudiada ha sido tanto la presencia de materia orgánica como la posible acción de las plantas en la retención de los radionucleidos estudiados.
