DEVELOPMENT OF A COUPLE OF METHODS FOR MEASURING RADON EXHALATION FROM BUILDING MATERIALS COMMONLY USED IN THE IBERIAN PENINSULA

摘要

Radon is considered to be the main contributor to the worldwide population exposure to natural sources of radiation and so a lot part of the radioactive decay series of uranium, which is also present in building materials. In this work, measurements of radon exhalation rates in building materials commonly used in the Iberian Peninsula have been carried out by using two different methods: active and passive techniques. In the first technique, the radon exhalation rate was measured following the radon activity growth as a function of time, by using a continuous radon monitor. The second technique is based on integrated measurements by using solid-state nuclear track detectors and a Spark Counter reading equipment. The results obtained by both measuring methods were found to be consistent.
