2.4 Design and theory of operation

2.4.1 The device consists of two independent modules:

- gamma radiation detection module (GMM);

- toxic substance vapor detection module (TSM).

The dose equivalent rate is registered in the mode of detection of exceeding the set

thresholds of gamma radiation using GMM based on the Geiger-Muller counter.

Exceeding of air concentrations of toxic substances vapors relative to set threshold level

is detected by using a TSM based on an ionizing chamber with 63Ni beta-source. An analyzed

air is pumped through the chamber using a micropump.

The principle of the device operation is based on comparison of the registered DER value

with the set DER threshold and the registered concentration value of toxic substance vapors

with the set threshold value of concentration level.

The detection modules are operated by a microprocessor controller with a built-in

analogue-digital converter (ADC).

The device is powered by two AA batteries. The nominal battery voltage is 1.5 V.

2.4.2 A block diagram of the device is presented in Figure 1.

The device consists of:

- gamma radiation detection module (GMM);

- toxic substance vapor detection module (TSM);

- microprocessor controller (MPC);

- audio alarm device (AAD);

- red light-emitting diode (R-LED) for alarming about exceeding a threshold of the toxic

substance vapor concentration;

- yellow light-emitting diode (Y-LED) for alarming about exceeding a threshold of the

gamma radiation DER;

- green light-emitting diode (G-LED) for indicating the device ON and the battery voltage;

- infrared interface (IRI);

- ON/OFF button (BN);

- batteries;

- micropump (MP).

Figure 1 –Block diagram of the device

The device operation algorithm provides for a continuous measurement, statistical

processing of measurement results, fast adaptation to variations of the radiation intensity (a

time of measurement is inversely dependent on the radiation intensity). An infrared interface

(IrDA) is used for an exchange of information between MPC and PC.

The device is equipped with a non-volatile memory used to accumulate and store

information.

2.4.3 Design of the device

2.4.3.1 The device is designed as a monoblock consisting of a toxic substances module

(TSM), a Geiger-Muller module (GMM), a printed circuit board of a microprocessor controller

(MPC) and a housing involving an audio alarming device (AAD) and batteries. The input

connecting pipe 2 of TSM (Figure 2) with a cap 15 is located on the top cover of the device.

When the device is operated the cap is taken off the connecting pipe 2 and fixed adjacent to the

connecting pipe at a plug 1. During the device calibration, the filter 14 involved in the set of

spare parts and tools (SET-O) is screwed on the connecting pipe 2. The Red-LED 4, Yellow-

LED 5, Green-LED 6 , ON/OFF button 8, window 7 of the IR interface and device serial number

3 are located on the front panel of the device.

The clip 13 is placed on the back side of the device. The Figure 2 shows how to mount

and remove the clip.

The Geiger-Muller module (GMM) is located in the bottom part of the device. The

housing 11 involving batteries and the audio alarming device (AAD) 12, as well as the cap 10 of

the output connecting pipe are fixed to the lower cover of the device.

The GMM effective center 9 is shown in Figure 2, and an arrow points a direction of

calibration.
