Evaluación de la concentración del gas radón en ladrillos artesanales en las parroquias: Juan Montalvo-San Sebastián e Ignacio Flores comunidad La Vicentina de la ciudad Latacunga, provincia de Cotopaxi

Abstract

The mass exhalation has been determined in handmade bricks built in factories in the city of Latacunga (sector: Juan Montalvo, San Sebastian and Ignacio Flores). It is important to consider the effect produced by radon gas in closed places built with this material. In this work we determined the properties of mud, sand and brick and how they influence the emanation and exhalation of radon gas; we also calculated the exhalation produced inside a typical building of this place. In the raw material the exhalation of radon gas are very limited due to the meteorological and geological conditions of the site (Palopo mine), with a radioactivity concentration content for mud (28.9391 plus minus 0.0150) Becquerel per cubic meter, for sand (3.3088 plus minus 0.0050) Becquerel per cubic meter and for bricks (9.7169 plus minus 0.0510) Becquerel per cubic meter. The annual effective dose is due to the inhalation of radon gas produced in a typical building in the sector, with a permanence of 5110 hours per year is 1.982 per 10 to the minus 3 thousand sievert per year. The dose rate of the building materials currently used as recommended by UNSCEAR is 1.1 thousand sievert per year.
