Page 10: Design And Principles Of Operation
5 DESIGN AND PRINCIPLES OF OPERATION 5.1 Overview 5.1.1 The dosimeter kit includes the control panel with a built-in gamma detector used to measure the operator's dose, and remote detecting units of gamma radiation and beta particles. 5.1.2 The control panel serves to perform: controlling operating modes of the dosimeter;... - Page 11 5.2.2 The control panel of the dosimeter (Figure 1) is designed as a rectangular parallelepiped with a slant in the upper part and rounded corners on the sides. The control panel includes the case consisting of the base (1), the frame (2) and the cover (3), and other component parts located inside. The main unit in the control panel is the printed circuit board of digital information processing with the energy-compensated Geiger-Muller counter.

- Page 14 The BDIB-07 detecting unit includes the case consisting of the base (1) and the cover (2), and other component parts located inside. In the lower part of the base, the connector (plug) HR-10A (3) is fixed, which is used for communication with the dosimeter’s control panel using a cable.
- Page 15 Figure 6 – BDIB-07 unit (bottom view) 5.3 Basic operation of the dosimeter 5.3.1 The dosimeter is switched on by pressing ON and holding it down for 4 s. This turns on the control panel and starts testing the dosimeter’s LCD. As soon as the LCD is tested, the dosimeter begins measuring photon ionizing radiation DE.

6 LABELING AND SEALING 6.1 The trademark, the name, the symbol of the unit, IP51 ingress protection rating and the approval pattern of the measuring instrument are inscribed on the control panel of the dosimeter. The cases of the detecting units contain the trademark, the name, the symbol and IP51 ingress protection rating. -
Page 17: Preparation For Operation
9 PREPARATION FOR OPERATION 9.1 Preparation of the dosimeter for operation 9.2 Study the operating manual and the control buttons before putting the dosimeter in operation. 9.3 Open the battery compartment of the control panel with the help of a screw driver. Make sure the four batteries are inserted, the connections are reliable, and there is no leakage of salts after the long-term storage of the dosimeter. - Page 18 Note. The type of the remote detecting unit is identified automatically after being connected to the dosimeter. The dosimeter enters the measurement mode of the corresponding physical units (photon ionizing radiation DER or beta particles flux density). 10.2 Switching the dosimeter on/off 10.2.1 Press shortly the ON button and hold it for 4 s to switch the dosimeter on.
- Page 19 The n number (a signaling divider) is generated so that at a current intensity of ionizing radiation intermittent beeps are produced about once per second. You can continue approaching the source of ionizing radiation. If ionizing radiation intensity is changed, you may press the PRECISELY button, i.e.
- Page 20 In the search mode, each gamma quantum is followed by a short audio signal, while exceeding of the threshold level is followed by a two-tone audio alarm and periodic blinking of the LCD digits. The arithmetic average of five last measurements should be considered as the DER measurement result in the search mode.
- Page 21 10.6 Measurement of surface beta particles flux density in search and precise modes 10.6.1 Connect the BDIB-07 detecting unit with the help of the connecting cable to the control panel of the dosimeter to measure surface beta particles flux density (hereinafter referred to as surface flux density) in the search and precise modes of measurement.
- Page 22 In the search mode, each registered gamma quantum or beta particle is followed by a short audio signal, while exceeding of the threshold level is followed by a two-tone audio alarm and periodic blinking of the LCD digits. The arithmetic average of five last measurements should be considered as the surface flux density measurement result in the search mode.
- Page 23 To exit the mode of precise measurement press the PRECISELY button and hold it down until multiple blinking of digits (in about 4 seconds). 10.6.4 Measurement of gamma background and saving it for further automatic subtraction in the mode of surface beta particles flux density measurement To measure gamma background and save it, perform the following operations in the mode of precise measurement of surface flux density:...
- Page 24 After all values are set, a short press of the PRECISELY button saves the new threshold level value in the memory. It is indicated by triple blinking of its new value on the LCD and dosimeter’s entering the search mode. 10.8 Indication of photon ionizing radiation DE measurement 10.8.1 DE measurement is performed continuously and irrespective of the selected mode of measurement and the type of the connected remote...

- Page 26 2 After saving the measurement result and the number of the studied object, the next saving is possible only after the next averaging time interval is finished. You have to wait for the next measurement result. It is impossible to save the same measurement result several times. 3 Recording of the measurement result and the number of the studied object when measuring surface beta particles flux density is possible only after the previous measurement and recording of gamma background value of the...
- Page 27 Press shortly the PRECISELY button to switch on the LCD between the display of measurement result and corresponding object number. "P" symbol that appears before the three-digit object number is an attribute of the object number. Figure 13 – LCD of the dosimeter (Measurement history viewing, measurement result display) Press the MEMORY button and hold it down for not less than 2 s, to exit the mode of the measurement history viewing.
