2.3.3.6 Measurement of photon-ionizing radiation characteristics.
2.3.3.6.1 To measure photon-ionizing radiation characteristics, the window of
the alpha, beta, gamma-radiation counter must be closed with Cover No.1 (energy
compensating filter).
The cover is fixed in the counter window by means of two protrusions and a
movable latch. The cover closes the counter from alpha and beta radiation, as well
as its application ensures energy dependence of the radiometer readings within the
limits specified in Table 1.1.
The radiometer should be oriented with the metrological mark "+", which is
affixed to Cover No.1, in the direction towards the object of examination.
2.3.3.6.2 The radiometer should operate in the mode of display of the measured
ionizing radiation characteristics. After turning on, the radiometer starts working in
this mode. You can also switch to this mode from any other mode by shortly
pressing MODE button.
