  1. A survey of 222Rn concentrations in domestic water supplies of Iran.

    Article - En anglais

    As part of a national program to determine public exposure to natural radiation, 222Rn concentrations were determined in domestic water supplies, including ground and surface waters, in 23 provincial centers using a liquid scintillation counting technique.

    The minimum and maximum mean concentrations of 222Rn in ground water were, respectively, 7.9±4.5 kBq m-3 in Sanandaj and 46.5±11.5 kBq m-3 in Tehran with an overall national mean value of 21±8.3 kBq m-3.

    The 222Rn concentrations in surface waters ranged from less than 1 to 7 kBq m-3 with a mean value of 3.9±1.9 kBq m-3.

    The mean concentration of 222Rn in tap water in different parts of Tehran is 3.8±1.1 kBq m-3.

    The results are presented and discussed in this paper.
