U-238, Th-232, Rn-222, and Rn-220 concentrations were measured in thirteen bottled mineral water samples from Morocco, France, and Italy widely consumed by the European population living in the city of Marrakech (Morocco) by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). K-40 contents were also evaluated in the same mineral water samples. The measured concentrations of U-238, Th-232, Rn-222, Rn-220, and K-40 ranged from (4.2 +/- 0.2) mBq L-1 to (8.6 +/- 0.6) mBq L-1, (0.90 +/- 0.05) mBq L-1 to (3.4 +/- 0.3) mBq L-1, (4.2 +/- 0.2) Bq L-1 to (8.6 0.6) Bq L-1, (0.91 +/- 0.06) Bq L-1 to (3.4 0.2) Bq L-1 and 15 mBq L-1 to 1,082 mBq L-1, respectively. Alpha activities due to the annual intakes of U-238, Th-232, and Rn-222 were assessed in the tissues and organs of the human body of the considered consumers. Committed equivalent doses due to annual intakes of U-238, Th-232, and Rn-222 were evaluated in the human body compartments of adult members of the European population living in Marrakech. The influence of the target tissue mass and activities due to U-238, Th-232, and Rn-222 on the annual committed equivalent doses in the compartments of the human body was investigated.
