MW-RN Protocol for the Collection, Transfer and Measurement of Radon in Water
This standard of practice contains minimum requirements and guidance for measuring radon in
water that enters a building through groundwater supplies for determining if mitigation is
necessary to protect current and future occupants of dwellings and other buildings. This
standard includes procedures for the collection and transport of water samples, as well as
protocols for the quantitative transfer of the sample to a measurement device to determine
radon concentrations in water.
