Cálculo estimado de la dosis radioactiva recibida por los trabajadores dentro de áreas mineras en el Cantón Riobamba.

Abstract

The present research aims at the calculation of effective doses in the mining areas of the Riobamba canton, where there are 21 construction materials mines in exploitation, distributed in the parishes of San Juan, Calpi, Quimiag, Punin, Cubijies, Licán and Maldonado. The study as performed using a Digital Geiger-Müller model GCA-07W. The measurements were made in 3 different points for each mining area obtaining a total of 9 radiation data, then the comparisons were made with the dose limits set by the International Atomic Energy Agency which establishes a limit of 20000 uSv / year) for workers over 18, and for public exposure the effective dose limit is 1000 uSv / year. As a result we have that the maximum effective dose rate detected is 425,813 uSv / year in the Culquiloma mine located in San Juan Parish, as compared to the effective dose limit (1000 uSv / year) we can say that no mine has a radiation risk for workers in mining areas. The research paper recommends to extend the present study with other experimental methods in order to know more specifically the radioactive elements that contribute with the detected effective dose.
