RADON MONITORING IN THE SOUTH ICELAND SEISMIC ZONE
Studies of radon concentration in water from geothermal wells were initiated in the South Iceland Seismic Zone in 1977 (Hauksson and Goddard, 1981) spurred by strong indications that radon changes occurred prior to earthquakes. After 18 years of monitoring radon using a labour intensive method (Luca...

| Summary: | Studies of radon concentration in water from geothermal wells were initiated in the South Iceland Seismic Zone in 1977 (Hauksson and Goddard, 1981) spurred by strong indications that radon changes occurred prior to earthquakes. After 18 years of monitoring radon using a labour intensive method (Lucas cell) on discrete samples, a greatly improved method, using a liquid scintillation (LS) detector, was developed in 1999, where 200 ml water samples were sent twice a week to our laboratory for radon measurement in a simple automatic sample changer (Guðjónsson and Theodórsson, 2000). In order to get a continuous radon record and reduce working time a new |
