The mean ac tiv ity con cen tra tions of 226 Ra, 232 Th, and 40 K were mea sured in nat u ral stone sam ples as 28.9, 30.8, and 355.0 Bqkg -1 , re spec tively. The as sess ment of ra dio log i cal haz ards from uti li za tion of stone sam ples as cov er ing or or na men tal ma te rial in build ing sec tor was made by es ti mat ing ac tiv ity con cen tra tion in dex, ab sorbed gamma dose rate and an nual ef fec tive dose rate. The ex am ined nat u ral stone sam ples were com posed of cal cite, do lo mite, quartz, orthoclase, al bite, bi o tite, hornblende, oligoclase, ol iv ine and talc.Key words: nat u ral stone, radioactivity, geo chem i cal char ac ter iza tion, min er al og i cal char ac ter iza tion, ac tiv ity con cen tra tion, an nual ef fec tive dose N.
