dc.description.abstractSeveral commercial granitic rocks are widely used as decorative material (ornamental stones) due to their durability and fantastic colors. The present study aims to identify the mineralogical constituents as well as natural radioactivity of seven granitic rocks known as Gandonna, Pink Granite, Fantazia, Buff granites I, Buff granites II, Qusseir brown, red granites in order to deduce their suitability for different applications (decorative stone). Accordingly, in the petrographic investigation, the examined rocks comprise different proportions of essential minerals (potash feldspar, quartz, and albite) with some secondary minerals such as kaolinite and chlorite minerals. 238U, 226Ra, 232Th and 40K activity concentrations were detected by using NaI (Tl) scintillation & gamma;-ray technique. Fantasia (av. 4.13 & PLUSMN; 5.85, 10.77 & PLUSMN; 1.9 Bqkg ? 1), and Gandonna (av. 12.4 & PLUSMN; 10.12, 35.01 & PLUSMN; 3.81 Bqkg ? 1) samples have the lowest mean 238U, and 232Th activities value, relative to other rock samples, which are lower than the recommended levels of UNSCEAR. Except for absorbed dose rate, numerous radiological indices such as outdoor and indoor annual effective dose, radium equivalent activity, external and internal indices, excess lifetime cancer risk and organs of effective dose are calculated for the examined stations to deduce the radiation effects on human organs. The obtained results reveal that the natural gamma radiation from these rocks is within acceptable limits.en_US
