Study of the contribution from gamma dose rate and radon concentration in civilian housing caused by the use of construction material having processing residues from uranium containing bituminous coal in Freital, Saxony

The past, widespread use of residues from processing uranium containing bituminous coal in the former mining region of Freital, Saxony, for construction led to increased concentrations of natural radionuclides in the building material of civilian housing. Measurement of the local dose levels in such housing, analytical characterization of the building material, and model calculations allow for the assessment of the contribution of the material to the total radioactive exposure of residents.
