Levels of 210Po in blood, urine and hair of some Saudi smokers

The activity concentration of 210Po was investigated in blood, urine and hair samples of some non-smokers, cigarette-smokers (tobacco-smokers) and shisha smokers (jurak- and mehassel-smokers). The results indicated that 210Po concentration was variable within each group of volunteers and fluctuated within certain range. The activity concentration in the blood of the non-smokers, the cigarette-smokers and the shisha-smokers was found to be ranged from 7-77, 17-86 and 22-92 mBq/l, respectively. These values were ranged from 1.5-10, 3.3-15.9 and 2.2-19.6 mBq/l in the urine samples of the same volunteers, respectively. The 210Po activity concentration in their hair was found to be ranged from 1.9-4.8, 1.9-6.4 and 2-6.5 Bq/kg, respectively. The obtained results are discussed and some conclusions, based upon the average values, were drawn.
