Radon Research

Comparison of Northern Ireland radon maps based on indoor radon measurements and geology with maps derived by predictive modelling of airborne radiometric and ground permeability data.

Synopsis

Abstract: An overview of ongoing directions of radon studies in the Faculty of Physics, St. Kliment Ohridski University of Sofia is presented. The focus is on: 1) Study and implementation of the polycarbonate method for measuring 222Rn. In this respect the results from laboratory and field experience with this method are summarized. Its potential for precise retrospective measurements by home stored CDs/DVDs is emphasized. 2) Surveys in radon risk areas in the country. The approaches and results in this direction are illustrated on the example of the town of Rakovski. In this town lung

There are potent defenses against the carcinogenic effects of ionizing radiation. Their efficacy is much higher for low doses and dose rates; this is incompatible with the LNT model but is consistent with current models of carcinogenesis. The data suggest that a combination of error-free DNA repair and elimination of preneoplastic cells furnishes practical thresholds.

An extraordinary incident occurred 20 years ago in Taiwan. Recycled steel, accidentally contaminated with cobalt-60 (half-life: 5.3 y), was formed into construction steel for more than 180
buildings, which 10,000 persons occupied for 9 to 20 years. They unknowingly received radiation doses that averaged 0.4 Sv - a collective dose of 4,000 person-Sv.
