| dc.description | In environmental monitoring the measurement of RaA activity concentrations is a reliable indicator of radon activity concentrations. Following a brief review of established methods of radon daughter activity concentration measurement, a method is given which enables activity concentrations as low as 0.05 pCi 1<sup>-1</sup> (50 pCi m<sup>-3</sup>) of RaA to be measured with simple readily transportable equipment. The method also measures RaB (<sup>214</sup>Pb) and RaC (<sup>214</sup>Bi) activity concentrations and working levels with improved precision compared with established methods. |
