2.3.3.2 Measurement of photon-ionizing radiation DER
The mode of photon-ionizing radiation DER measurement is entered automatically after
the dosimeter is switched on. The mode is indicated by the blinking light-emitting diode
opposite the appropriate mnemonic symbol below the LCD. The results of measurement will
appear on the LCD during the first few seconds, enabling efficient evaluation of radiation
level. The LCD will blink until the statistically processed reliable information is gained. The
statistical processing period will depend on the radiation intensity. Units of measurement are
expressed in µSv/h.
To measure photon-ionizing radiation DER, direct the dosimeter with its metrological
mark "+" towards the examined object. A filter cover should cover the window with the
detector located behind it (hereinafter the window of the detector).
