Investigation of Building Materials and the Street’s Surface Radioactive Emission

Abstract

Protection of the environment is becoming more important role as pollution and magnetic loads from electronic devices are growing as never before. The radioactive background radiation does not explore explicit increase nevertheless more and more attention is paid to this. An increasing number of countries are paying more attention to measurements of the levels of background radiation from various radioactive sources and to the values of their exposure limits.
It is known that the vast majority of background radiation in the enviroment comes from radioactive construction (buildings, roads, etc.) built by humans. It is important to understand its sources, evolution, determining parameters, etc. Radioactivity of the human-built environment is assessed on the basis of building materials, construction techniques, and dose-loading related to building technologies.
The Department of General and Environmental Physics in the Juhász Gyula Teacher Training College at the University of Szeged (Hungary) out radioactive measurements related to background radiation, especially the absorbed dose load from full gamma radiation. Among a wide range of measurements, the most important are:
The power of radiation from walls and other parts of buildings.
The field, such as radioactivity mapping of the environment. Using maps, we not only have actual data for the radioactivity, but we can follow the impact of the human-built environment (buildings, streets, etc.) on whole background radiation (Köteles, 1994).
