title: Radon estimation in some Indian tobacco, tea and tooth powder using CR-39 nuclear track detector.
abstract: Radon contents in some samples of tobacco, tea and tooth powder have been estimated using CR-39 solid state nuclear track detectors. The Radon content in tobacco has been found to vary from 14.06 +/- 1.4 to 89.91 +/- 3.3 mBq/l. The Radon content in tea and tooth powder has been found to vary from 27.38 +/- 1.8 to 41.81 +/- 2.2 mBq/l and 26.27 +/- 1.4 to 413 +/- 6.0 mBq/l respectively. The present investigations are useful from the health hazards point of view.
