Abstract

Covering or decorative building materials derived from
rock and soil include primordial radionuclides such as ²³⁸U and ²³²Th
series, and potassium radioisotope (⁴⁰K) varying from one country to
another and from one location to another in the same country. The kinetic
energy of radiation emitted from these radionuclides in the covering building
materials like other building materials are sources of radiogenic heat. Marble
tiles are commonly used as wall and floor covering, facing materials for
buildings, kitchen counter- top, vanity tops and inner and outer decorative
materials because of their appearance, attractive colours, polished surface and
durability against external conditions and high resistance to wear. In this
study, radiogenic heat productions of marble and glazed tiles samples are
calculated based on the elemental concentrations of uranium (in terms of
mg/kg), thorium (in terms of mg/kg) and potassium (in terms of %) in the
samples collected from various provinces in Turkey.  The radiogenic heat productions from the
marble tile samples varied from 0.05 to 2.17 µW/m³ with an average
of 0.26 µW/m³. The average the radiogenic heat production of the
marble tile samples is approximately four times lower than the average
continental crust of 0.9 µW/m³.
