To measure photon-ionizing radiation DER, direct the radiometer with its
gamma and beta detector (9) (Figure 2) towards an examined object. The beta-filter
cover (10) should cover the detector.
In this mode the radiometer’s LCD displays the following information (Figure
3):
- statistical error (1) of the measurement result (7);
- “γ” symbol (2) – an indication of the measured radiation type;
- instantaneous value indicator of radiation intensity (3);
- sound symbol (4) (if audio signaling of registered gamma quanta is switched on);
- alarm clock symbol (5) (if the alarm clock is on);
- battery status symbol (6);
- measurement result (7);
- dimension of measurement result (8);
- current time (9);
- threshold level of alarm actuation (10).
