| Summary: | Feldspar, which constitutes 60% of the earth's crust, is one of the most important mineral groups. Feldspar zones and deposits are formed by cooling and crystallization of these minerals in different shapes in different parts of magma. Feldspar reserves in many sectors of an important raw material in especiaaly ceramic, porcelain and glass industries including about 14% are in Turkey. In this sense, Turkey, is located in the rich world feldspar category in terms of reserves and has a significant share of exports. Although the evaluation of reserve resources is a priority issue of mining in the country, it is very important to know the radioactivity levels of 226Ra, 232Th, 40K and 137Cs isotopes contained in the raw material used in the construction of residential and business buildings. To this end, Turkey's most important zones (Aydin, Mugla, Manisa and Kirsehir) of feldspar mine using samples obtained from the bed where radioactivity analyzes were performed. As a result of the analyzes using gamma spectrometric method, the mean activity concentrations of 226Ra, 232Th, 40K and 137Cs radioisotopes were 11.94 +- 3.8, 4.28 +- 1.7, 879.26 +- 56.3 and 1.9 +- 0.7 Bqkg-1, respectively. And than Radiological risk analysis was performed. |
