  1. Distribution of indoor radon levels in Mexico.

    Article, Communication - En anglais

    International Conference on Nuclear Tracks in Solids. Besançon, FRA, 1998/08/31.

    Our laboratory has carried out a systematic monitoring and evaluation of indoor radon concentration levels in Mexico for ten years.

    The results of the distribution of indoor radon levels for practically the entire country are presented, together with information on geological characteristics, population density, socioeconomic levels of the population, and architectural styles of housing.

    The measurements of the radon levels were made using the passive method of nuclear tracks in solids with the end-cup system.

    CR-39 was used as the detector material in combination with a one-step chemical etching procedure and an automatic digital-image counting system.

    Wherever a high level was measured, a confirming measurement was made using a dynamic method.

    The results are important for future health studies, including the eventual establishment of patterns for indoor radon concentration, as it has been done in the USA and Europe.
