  1. Fulltext. Radium-bearing pipe scale deposits : implications for national waterborne radon sampling methods.

    Article - En anglais

    Fulltext.

    A point-of-use waterbone randon-222 (222Rn) survey of a small Iowa town was performed to determine the cause of unnaturally high waterbone 222Rn concentrations in the municipality.

    The source of the elevated 222Rn concentrations was a newly discovered reservoir of waterbone 222Rn originating from distribution-system radium-226 (226Ra) adsorbed internal pipe scale deposits.

    Because the proposed national drinking water regulations for 222Rn require sampling at the origin of the distribution system rather than at the point of use, the proposed scheme for collection of water samples may not represent actual consumer water-bone 222Rn exposure in all cases.
