INTERNATIONAL CONFERENCE AND MEETING
ON RADIOPROTECTION
TORINO, ITALY
POLITECHNICAL UNIVERSITY OF ENGINEERING
MAY 3RD - MAY 10TH, 2014.
The building industry uses large amounts of waste products from other industries. In recent
years, there is a growing tendency to use new construction materials with naturally or
technologically enhanced levels of radioactivity (e.g. phosphogypsum, coal fly ash, oil shale
ash, some rare minerals, etc.). Therefore, most building materials contain naturally occurring
radioactive elements, the most important of which are 40K and members of two natural
radioactive series, which can be represented by the isotopes 232Th and 226Ra. The presence of
these radioisotopes in materials causes external exposure to the people who live in the
building. 226Ra and 232Th can also increase the concentration of 222Rn and 220Rn and of its
daughters in the building. 40K and part of the above-mentioned radionuclides cause external
exposure while the inhalation of 222Rn, 220Rn and their short lived progeny leads to internal
exposure of the respiratory tract to alpha particles. Increased interest in measuring
radionuclides and radon concentration in building materials is due to the health hazards and
environmental pollution. Timber-based building materials have low concentrations of natural
radioactive substances. In stone-based building materials the concentrations depend on the
constituents. Materials used by the building industry that maybe of radiological significance
include marl, blast furnace slag, fly ash, phosphogypsum, Portland cement clinker, anhydrite,
clay, radium-rich and thorium-rich granites (used as aggregates in concrete or in dimension
stone products). Most individuals spend 80% of their time indoors and natural radioactivity
in building materials is a source of indoor radiation exposure. Indoors-elevated dose rates
may arise from high activities of radionuclides in building materials.
