Follow the procedure:
- close the beta detector window;
- place BG probe with the closed beta detector window so that it was in
parallel to and at a minimum distance from the surface to be examined;
- restart the measurement process by shortly pressing RAYS/RESTART;
- wait for measurement results of gamma-component with minimum possible
estimated limits of statistical deviations;
- press MODE and hold it down until a blinking “

” symbol appears ((2)
Figure 2.18) to save the result of gamma-component measurement.
If you change the object of examination, clear the saved value of gamma
radiation component and measure and save the new value of gamma-component in
the immediate proximity to a new surface to be examined.
Press MODE and hold it down until a blinking “

” symbol disappears to clear
the saved value of gamma-component.
2.3.6.6.5
Submode of the control unit of the dosimeter “Saving
measurement result of beta radiation characteristics in the nonvolatile
memory”
2.3.6.6.5.1 It is only possible to save the measurement result if gamma
radiation component is considered during measurement of beta radiation
characteristics. The LCD of the dosimeter displays a blinking “γ” symbol (2) (Figure
2.18).
2.3.6.6.5.2 Saving measurement result of beta radiation characteristics in the
nonvolatile memory of the control unit is similar to saving measurement result of
DER measurement (2.3.6.5.4 of this OM).
2.3.6.7 Measurement of alpha radiation characteristics
2.3.6.7.1 General information
2.3.6.7.1.1 Alpha radiation characteristics, such as surface alpha particles flux
density and surface activity of alpha-emitting radionuclides can be measured using
ABG probe.
2.3.6.7.1.2 Follow 2.2 of this OM (Preparation to operation) to connect the probe
to the control unit.
2.3.6.7.1.3 Open the alpha detector window and place the probe so that the
window of its alpha detector was in parallel to and at a minimum distance from the
surface to be examined.
