Abstract : The nuclear gauge consists of a radioisotope which can be applied to the exterior of superheater tubes, and a geiger counter tube which can be inserted into the boiler tubes from the header. A sectional drawing of the arrangement is shown. The principle of the nuclear gauge is based on the absorption of radiation by the steel tube wall; the thicker the tube, the lower the count, and the more wastage, the higher the count.
