“…Since these rays are electrically charged, they can attach to dust particles, especially in a closed environment. These dust particles can also be easily inhaled and stick to the lungs [119,120]. As radon gas disperses into the atmosphere, solid radon products are stored in water and soil and are involved in the food chain [20,121].…”

A comprehensive evaluation of the results obtained according to the measurement of radon gas in buildings and concrete, which is the most consumed material in the world after water, in accessible studies carried out in the last 40 years is the main objective of this study. The paper additionally aims to address the gap in the literature by comparatively determining which parameters affect radon–concrete and radon–building relationships. The scientific knowledge compiled within the scope of this article was presented under the main headings of radon and radon gas measurements in concrete and buildings. Radon gas, also known as the “invisible killer”, is considered the second most important cause of lung cancer after smoking (the gas is responsible for 3–14% of lung cancer cases in the world). The results determined that radon concentration limits have been applied in the range of 100–400 Bqm−3 in houses and 100–3700 Bqm−3 in workplaces. Studies conducted on the exhalation rate of radon showed that the radon exhalation rate of concrete may be in the range of 0.23–510 Bqm−2 h−1. The results of indoor radon concentration measurements revealed that values between 4.6 Bqm−3 and 583 Bqm−3 were obtained. Despite the existing literature, some researchers state that there is an urgent need for an improved and widely accepted protocol based on reliable measurement techniques to standardize measurements of the radon exhalation rate of construction materials and the indoor radon concentration of buildings.

“…This can be ensured by using real-time direct-reading measurement devices (DURRIDGE Company) capable of detecting and quantifying the presence of 222 Rn in the air. When such devices are not available, measurements can be conducted using diffusion chambers with nuclear track detectors LR-115 [5]. This measurement method proves to be highly efficient in ensuring measurements over extended periods (weeks to months), enabling the identification of areas with higher 222 Rn concentrations and the implementation of necessary measures to ensure radiological protection for workers, which is the measurement system used in this research.…”

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.
