5.1

General Count Rate Measurements (cps; cpm)

These are the most general measurement units (cps = counts per

second; cpm = counts per minute). The displayed value is inde-

pendent of any specific calibration factor which may not be avail-

able for a contamination with unknown nuclides. Either gross

count measurements or net count measurements can be per-

formed. The selection can be performed by the PC-settings or in

the menu <Background> by tagging <Ratem. netto> and/or

<Scaler netto>. The background count rate for these netto meas-

urements can be determined via a background measurement in the

menu <Background>. The derived background count rate can be

stored and is used for all following net measurements. This value

is always displayed in the top section of the LCD in order to re-

mind the user that the measured value has been corrected by that

particular count rate value.
