| description |
The concentrations of radon 222Rn can be quantified using active and passive measurements (in situ). This radioactive gas in enclosed spaces such as underground coal mines is a silent threat because inhaling it at high concentrations can induce lung cancer in workers exposed for extended periods. Currently, Colombia lacks protocols for the measurement and prevention of this radioactive gas. Therefore, the primary objective of this study is to measure the concentrations of 222Rn to which the workers in the El Volca ́n coal mine, located in the municipality of Corrales in the Boyaca ́ department of Colombia, are exposed. To achieve this, a radiological mapping was conducted inside the mine using nuclear track detectors placed within diffusion chambers. A total of 32 measurement points were monitored over a 60-day period, obtaining 222Rn activity concentrations rangingfrom700to2000 Bq·m−3.WhencomparedtothepermissiblelimitsrecommendedbytheICRP,thesemeasurements fall within the allowed range for enclosed spaces. These measurements were extrapolated to calculate the probability of radiological risk associated with lung cancer in this specific mine. In conclusion, the calculations show low concentrations of this radioactive gas, 222Rn, and consequently, low doses absorbed by the personnel.

Las concentraciones de radón 222Rn se pueden cuantificar usando mediciones activas y pasivas (in situ). Este gas radiactivo en espacios cerrados como las minas subterráneas de carbón es un enemigo silencioso, debido a que su inhalación en altas concentraciones puede inducir un cáncer de pulmón en los trabajadores de este entorno cuando son sometidos a largos periodos de exposición. Actualmente Colombia no cuenta con protocolos de medición y prevención de este gas radiactivo, por lo que el principal objetivo de este trabajo es medir las concentraciones de 222Rn a las cuales están expuestos los trabajadores de la mina de carbón El Volcán ubicada en el municipio de Corrales en el departamento de Boyacá, Colombia. Para esto, se realizó un mapeo radiológico al interior de la mina utilizando detectores de trazas nucleares ubicados al interior de cámaras de difusión. Un total de 32 puntos de medición fueron monitoreados durante un periodo de 60 días obteniendo tasas de dosis que oscilan entre 700 - 2000 Bq * m^-3, que al ser comparados con los límites permisibles recomendados por la ICRP encontramos que se encuentran dentro del rango permitido en espacios cerrados, estas mediciones fueron extrapoladas para calcular la probabilidad de riesgo radiológico asociado a cáncer de pulmón en esta mina en particular En conclusión, de los cálculos realizados encontramos bajas concentraciones de este gas radiactivo 222Rn y por consiguiente baja dosis absorbidas por el personal.
