N2  - Five concrete pads containing elevated concentrations of the three radioelements, potassium, uranium and thorium, have been constructed at the CSIRO lnstitute of Energy and Earth Resources, North Ryde. Analyses of samples taken during construction showed that the pads are homogeneous, and radiation monitoring with a calibrated instrument showed that radioelement concentrations are in agreement with those assigned to similar facilities in Canada, Finland, Sweden and the USA. The North Ryde facility is available to users of gamma-ray spectrometers wishing to calibrate their instruments.
