Patent
Process and device for concentration measurement of the different radon isotopes in a gaseous atmosphere
Description
The process for measuring radon isotope concentration in a gaseous atmosphere, especially radon 222, radon 220 and radon 219, is characterized by collection and homogeneous repartition of solid daughter products in a sampling vessel containing a sample of the atmosphere and spectrometric determination of emitted γ radiation

Le procede de mesure de la concentration dans une atmosphere gazeuse des differents isotopes du radon, tels que notamment le Rn222, le Rn220 et le Rn219, se caracterise en ce qu'il consiste a collecter et a repartir de facon homogene, dans un espace ferme de prelevement contenant un echantillon de cette atmosphere, les descendants solides de ces isotopes et a effectuer de l'exterieur de cet espace, une spectrometrie des rayonnements γ qu'ils emettentAdditional details
