Abstract
A very simple emanation method for determining radium is described. Radon is adsorbed on silica gel at the temperature of liquid nitrogen and the silica gel is transferred at 0 °C to a toluene-based liquid scintillator for counting in an automatic liquid scintillation spectrometer. the lowest limit of detection is 0·1 pCi of radon.Keywords
