“…A total of 164 samples were collected (table 1). The sampling employed was the one used by the Radiation Monitoring Network in Spain according to the ReViRa (for its acronym in spanish) Manual from Spain (ReViRa, 1994), and mentioned in other works (Blanco, VeraTomé & Lozano, 2005;Colmenero-Sujo et al, 2004;Rentería-Villalobos et al, 2007). This method use a square steel structure, 50 cm length and 5 cm depth, which was placed on the ground to define the soil sample (approximately 12.5l).…”

“…Moreover, many countries have published their own averages (Bassioni et al, 2012;Dolhań czuk-Ś ródka, 2012; García-Talavera, Mexico uranium deposits are not commercial grade. The State of Chihuahua is considered the most important uraniferous site with 50 natural zones with about 30% of all the uranium of Mexico (Bazán-Barrón, 1978;Burciaga-Valencia et al, 2010;Colmenero-Sujo et al, 2004;Domínguez, Hernández, Arango & Medina, 2006;Rentería-Villalobos et al, 2007;Villalba et al, 2006;Villalba, Colmenero-Sujo & Montero, 2012). Figure 1 shows the 12 most important uraniferous zones; some of them are near (underled uraniferous zones) large cities.…”

“…In this study, it was assumed that the accumulated gamma dose measured by TLD represents a total external dose rate. The dose rate is calculated by the equation, 3) H ex = 0.0087 G g C T (Sv/y) (2) where H ex is the effective dose rate, G g is the dose conversion factor from the absorbed dose (= 0.7 Sv/Gy) 3) and C T is the accumulated dose in TLD, in mR/y.…”

The radiation dose was assessed for the inhabitants living in the Kumsan, Geosan and Miwon regions which belong to an Okchun metamorphic belt with plenty of uranium resources. The grain, vegetable, milk, and water, which the inhabitants generally ate or drunk, were sampled to reflect the dose effects. And TLD (Thermoluminescence dosimeter) was used for measuring the external dose in the sampled area. An external exposure includes the accumulated gamma dose measured by TLD and an internal exposure includes an ingestion of the food, and an inhalation of the air and radon gas. The radionuclides such as Rn concentration of indoor air significantly contributed to the total effective dose where the concentration of these uranium belt regions was more or less higher than the average domestic one. This study revealed that the dose level for the inhabitants of the uranium rich regions in Korea was similar to that of the other regions except for the effect by radon.

“…En el estado de Chihuahua, México, a partir del año 2000 se han realizado estudios referentes a la radiactividad en sedimentos, suelo, aire y agua (superficial y subterránea) en diferentes localidades (Villalba et al, 2011;Colmenero-Sujo et al, 2004). Sin embargo, los estudios que involucran aspectos de radiación en aguas recreacionales y salud humana, han sido poco documentados.…”

La radiación en aguas termales utilizadas como zonas recreativas puede representar un problema de salud pública. El objetivo fue cuantificar el nivel de radón (222Rn) en aire y evaluar la dosis de radiación en los baños termales establecidos en San Diego de Alcalá, Chihuahua, México. Se seleccionó un espacio de esparcimiento, se cerró puerta y ventana para simular la utilización del baño termal por el público. El nivel de 222Rn en aire se detectó utilizando un instrumento AlphaGUARD (Professional Radon Monitor) de la marca GENITRON. Éste se cuantificó en Bq m-3 en diferentes tiempos 10, 20, 30, 40, 50 y 60 min, se realizaron tres mediciones; la primera en la epoca de invierno 2014 (enero) y dos en la epoca de primavera de 2015 (mayo y junio). El análisis estadístico fue mediante una regresión para cada medición. Se estimó la Dosis Promedio Anual (DPA) efectiva de inhalación de radón a la que se encuentran expuestas las personas que acuden a los baños termales dependiendo del número de visitas y tiempo de permanencia, el rango varió de 0.0005±4x10-4 mSv cuando se visitan los baños 12 veces al año con un permanencia de 10 minutos, hasta 0.0352±1.1x10-2 mSv visitando una vez a la semana por un periodo de 60 minutos.
