1.4 (2) s. Rn-218 . The principle of the procedure is described in procedure H-Ra-226-TWASS-01. It is based upon recording the alpha emissions by Rn-222 and its decay The Ra-226 content is determined by measuring the alpha radiation emitted by the daughter nuclide Rn-222.

A metallic element, atomic no. 88, extracted in very minute quantities from pitchblende; 226 Ra, its longest-lived isotope, is produced as an intermediate in the uranium series by the emission of an α particle from thorium-230 (ionium); 226 Ra emits α particles and gamma rays with a half-life of 1,599 years breaking down to 222 Rn; chemically, it is an alkaline earth metal with properties We describe a very sensitive system for the Rn-222 and Ra-226 assay of water that we have constructed within the framework of the BOREXINO solar neutrino experiment. The technique that is applied for Rn-222 measurements is based on concentration of radon from water samples followed by gas purification and subsequent alpha counting in low-background miniaturized proportional counters. 226.
