This work reports the measurements of the radionuclide contents in some widely read daily newspapers published in Nigeria, using gamma spectrometry. The radionuclides detected in the newspapers measured consisted of the natural radionuclides belonging to the series headed by Ra and Ra as well as the singly occurring radionuclide K. The mean activity concentrations obtained for K, Ra and Ra respectively in the newspapers were 183.41±135.43, 9.06±3.64 and 6.11±1.36 Bqkg, 139.10±90.38, 7.58±1.87 and 5.29±1.33 Bqkg and 152.10±114.32, 9.62±1.40 and 5.76±1.29 Bqkg respectively from P1, P2 and P3. The doses to the eyes due to the measured activity concentrations in the newspaper samples were determined for a distance of 0.25 m (least distance of distinct vision) from the eyes. The annual effective doses to the eye resulting from the activities of the radionuclides identified with observed regularity in all the newspaper samples, obtained in this study are 0.012±0.010, 0.010±0.009, 0.010±0.009 μSv y respectively for the newspapers. These values show that the doses to the lens of the eye from the Nigerian newspapers assessed in this work are very low compared to the annual dose limit of 15 mSv y.
