“…27 The value of radon concentration is almost twice the world’s average value 37 Bq/m 3 . 28 Fifty-six per cent of homes in villages recorded C Rn220 /C Rn222 > 1 in the present study. Higher value of thoron concentrations was recorded in the nearby areas, Himachal Pradesh and Haryana state, India also.…”

In the present study, indoor radon and thoron concentrations were assessed using a newly developed pin hole-based twin cup dosimeter with a single-entry face in some areas of Punjab state, India. The equilibrium equivalent concentrations of radon and thoron were estimated directly by using the newly developed progeny (decay products) sensors designed by Bhabha Atomic Research Centre, Mumbai, India. The average radon and thoron concentrations in the study region were found to be 61.6 ± 18.6 Bq/m3 and 68.0 ± 30.8 Bq/m3, respectively, while the average equilibrium equivalent concentrations of radon and thoron were 25.9 ± 7.7 Bq/m3 and 2.2 ± 0.7 Bq/m3, respectively. Calculated average equilibrium factor for radon and thoron was 0.45 and 0.04, respectively, in the present study. The annual inhalation dose that was calculated from the present observed concentrations varied from 1.1 to 4.1 mSv/year with an average value of 2.4 mSv/year, which is well within the reference level of 10mSv/year recommended by International Commission on Radiological Protection. The study shows that thoron is a significant contributor to the inhalation dose, which is about 29% of the total inhalation dose.

“…In its 2019 report, UNSCEAR reviewed dosimetric calculations for radon progeny exposure in homes, indoor workplaces and mines published after 2006 (Table 6). The data given in the UNSCEAR report show that calculations with the HRTM for exposures in homes gives a range from 13 to 21 mSv per WLM with a mean of 16 mSv per WLM (37,40,76,77,78,79,80). Lower values were obtained with deterministic and stochastic airway generation models, ranging from 8-12 mSv per WLM with a mean of 9 mSv per WLM (24,38,39,81,82).…”

Radiation Protection Dosimetry

The International Commission on Radiological Protection (ICRP) publishes guidance on protection against radon exposure in homes and workplaces. ICRP Publication 137 recommends a dose coefficient of 3 mSv per mJ h m−3 (~10 mSv WLM−1) to be used in most circumstances of radon exposure, for workers in buildings and in underground mines. Recently, United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reviewed radon epidemiology and dosimetry and concluded that its established dose coefficient of 1.6 mSv per mJ h m−3 (5.7 mSv WLM−1) should be retained for use in its comparisons of radiation exposures from different sources in a population. This paper explains and compares the reviews of the scientific evidence from UNSCEAR and ICRP. It is shown that the UNSCEAR and ICRP reviews are consistent and support the use of the ICRP reference dose coefficients for radiation protection purposes. It is concluded that the ICRP dose coefficient should be used to calculate doses to workers.

“…La EPA (2015) ha reportado hasta 21,000 casos anuales de muerte por cáncer de pulmon donde 2,900 eran no fumadores. El aumento de la dosis por estas causas puede desarrollar en el futuro, un proceso que genere células cancerígenas a lo largo de los años (Ruano y Barros, 2013;Al-Jundi et al, 2011). Para reducir este riesgo, es necesario que el tiempo de permanencia y el número de visitas sean las menores posibles.…”

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.
