The 222Rn concentration level has been surveyed inside dwellings in the seven more important and populated cities of Mexico, and the results are presented in this work.
The measurements were made for six months, covering winter and spring, the coolest seasons of the year in Mexico.
More than a hundred dwellings in each town were chosen, selecting three groups of basic architectonic styles.
Different factors affecting the potential 222Rn concentration were considered in the study : construction materials, age of the dwellings, wall coverings, location of sites, and meteorological parameters such as indoor-outdoor temperature and relative environmental humidity.
The passive integration of radon measurement method based on nuclear tracks was used.
The closed end cup device, developed at the Institute of Physics of the University of Mexico, with CR-39 polycarbonate as material detector was chosen.
The measurement methodology consists of the one step chemical etching process to develop the nuclear tracks and automatic track reading by a digital image analyser.
