Assessment of natural radioactivity levels and annual equivalent doses in some milk powdered samples for adults used in Baghdad

الملخص EN

In this paper the specific activity of 238U, 232Th and 40K radionuclides were determined by sodium iodide enhanced by thallium NaI (Tl) detector and assessment the annual effective dose in samples of powder milk from different companies such as Almunaish, Seven Caw, Molty and Altunsa for adult available in Baghdad markets.

The specific activity of 40K has the greater value in all the samples which is in the range of allowed levels globally that suggested by UNSCEAR.

The mean value of annual effective doses were 0.121, 0.314775 and 0.305 mSv/y for 238U, 232Th and 40K respectively
