QCYK Reference material - 0 to 200 keV

Home Page | Examples | 200 to 700 keV | 700 to 1200 keV | 1200 to 2000 keV | Calibrations

This spectrum was measured using a 45% n-type detector, mounted in a standard 10cm thick cylindrical graded shield. The source was the QCYK reference material evaporated onto a 5 cm diameter filter paper placed, within a polystyrene counting container, at the centre of the detector face. Such a counting position invites true coincidence summing! Peak attributions below 50 keV are tentative at best. There are many overlapping X-rays, which GammaVision has not necessarily deconvoluted correctly.
