<sup>222</sup>Rn is an inert radioactive gas that is generated by the decay of <sup>226</sup>Ra (which forms part of the <sup>238</sup>U series of natural radionuclides). Knowledge of activity concentrations of <sup>222</sup>Rn in hot spring waters is of interest since it can provide new insight into the hydrogeology of the spring area and because it allows one to make estimates of the ionizing radiation dose to workers and public residing in these areas. It is well known that <sup>222</sup>Rn has a significant contribution to the background radiation dosage. It is thus of importance to develop and optimize <sup>222</sup>Rn detectors for a large array of sample types. The RAD 7 will be used as an alpha-spectrometer to verify the decay constant of <sup>222</sup>Rn using split <sup>222</sup>Rn-rich water samples (from a borehole) which are measured over a period of days.
