The method of obtaining the spectrometer channel width, peak width and peak to total efficiency are described. The calibration was achieved with standard sources and a multichannel analyser. The results were compared with data from other workers and reasonable agreement demonstrated. The conversion of peak height to photon flux or dose is obtained from a series of graphs obtained by calibration or, less accurately, from a nomogram. The spectrometer (E.A.L. type no. NIS 292) is used for surveying around nuclear installations.
