Abstract
Environmental measurements of Radon and its progeny were carried out in a gold mining area in the department of Antioquia, Colombia. Radon concentration measurements were carried out during 2 y in seven different measurement points in three types of geological zones, by using EPERM electret chambers and DOSEman Pro detectors at each point. Radon concentration values between 858 ± 59 Bq m-3 and 2469 ± 158 Bq m-3 and an equilibrium factor between 0.15 and 0.27 were found. The annual effective dose, taking into account the radon concentration, was determined under two calculation methodologies ([1] and International Commission of Radiological Protection 137), obtaining values of up to 7.7 mSv, and 13.5 mSv, respectively, for 2000 annual working hours, which shows the importance of the dosimetric data and epidemiological studies carried out year after year to reduce the uncertainties regarding estimates of radon exposure and the need to carry out individual monitoring of miners.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
