Specific Activities and Annual Effective Dose of Natural Radionuclides Due to the Intake of Some Types of Sugar Available in Baghdad Markets
In this research the specific activity of natural radionuclides 226 Ra, 232 Th and 40 K were determined by sodium iodide enhanced by thallium NaI (Tl) detector and assessed the annual effective dose in Beladi, Aldar, Alusraa, Alkhaleej and Aletehaad which are available in Baghdad markets. The specific activity of 40 K has the greater value in all the types which is in the range of allowed levels globally that suggested by UNSCEAR. The mean value of annual effective doses was 0.198, 0.094 and 0.098 mSv/y for 226 Ra, 232 Th and 40 K respectively.
