QCYK Reference material - 1200 to 2000 keVHome Page | Examples | 0 to 200 keV | 200 to 700 keV | 700 to 1200 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!
