Radioactivity of building materials and the gamma radiation in dwellings. 1979

E Stranden

Measurements of the radioactivity in some common building materials in Norway are reported, together with calculations of the gamma-ray exposure from walls of different materials. Model rooms are used in calculations of the mean exposure inside concrete, brick and light-weight expanded clay aggregate buildings. These calculations give very good agreement with previous experimental results. The radiological implications of using building materials with high concentrations of radioactivity are also discussed.

UI	MeSH Term	Description	Entries
D009664	Norway	A country located in northern Europe, bordering the North Sea and the Atlantic Ocean, west of Sweden. The capital is Oslo.	Kingdom of Norway
D011839	Radiation, Ionizing	ELECTROMAGNETIC RADIATION or particle radiation (high energy ELEMENTARY PARTICLES) capable of directly or indirectly producing IONS in its passage through matter. The wavelengths of ionizing electromagnetic radiation are equal to or smaller than those of short (far) ultraviolet radiation and include gamma and X-rays.

D003252	Construction Materials	Supplies used in building.	Building Materials,Building Material,Construction Material,Material, Building,Material, Construction,Materials, Building,Materials, Construction
D005720	Gamma Rays	Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.
