The detection unit BDMG-04
|
Blocks detection BDMG-04-00, BDMG-04-01, BDMG, 04-02, 04-03 and BDMG-BDMG-04-04 designed to measure equivalent dose of gamma radiation (hereinafter - EDR gamma . -radiation)
BDMG-04-02B detection unit is designed to measure the absorbed dose rate in air of gamma radiation (hereinafter -. gamma MTD)
detection units include to stationary facilities of measuring technique (SIT), which serves for radiation monitoring, and are exposed to the state tests according to DSTU 3400: 2006
detection units are used:.
- a part of the radiation safety monitoring equipment (AKRB) at nuclear power plant (NPP);
- together with conventional SIT (dosimeter radiometer ISS-2001, a parallel multichannel analyzer account AMP-12 "pulse-1A" et al.);
- in conjunction with a standard electron-physical equipment having respective inputs (for receiving statistically sequence p aspredelennyh pulses, RS-485 or current input).
Specifications
Energy range of gamma radiation from 0.05 to 3.0 MeV.
measurement range EDR and MTD gamma radiation for each of the embodiments of detection units is given in table:
| An embodiment of the | measuring range | Note: | BDMG-04-00 | from 0,04 ∙ 10 -6 to 10 Sv / h | Two channels : №1 (with counter high sensitivity) and №2 (with counter of low sensitivity) | BDMG-04-01 | 1 ∙ 10 -6 to 10 Sv / h | Two channels: №1 (with an average sensitivity of the meter ) and №2 (with counter low sensitivity) | BDMG-04-02 | from 0.04 ∙ 10 -6 to 4 ∙ 10 -3 Sv / h | | BDMG-04-03 | from 0,1 ∙ 10 -3 to 10 Sv / h | One channel (with low sensitivity counter) | BDMG-04-04 | 1 ∙ 10 -6 50 ∙ 10 < sup> -3 Sv / h | One channel (with an average sensitivity counter) | BDMG-04-02B | from 0.04 ∙ 10 -6 to 4 ∙ 10 -3 Gy / h | One channel (with counter high sensitivity), measures MTD gamma | specifications operating Conditions versions The blocks are detected Ania BDMG-04-02, BDMG-04-02B, BDMG-04-03 and BDMG-04-04 are composed of one meter. Detection units BDMG-BDMG-04-00 and 04-01 are composed of two counters. Each of the counters is a part of a separate measuring channel (coarse and delicate - for BDMG-04-00, coarse and medium sensitivity - to BDMG-04-01) Case of detection units is configured as a cylinder material. housing - an aluminum alloy. Dimensions embodiments of detection units differ only in length (from 230 to 420 mm) diameter -. 50 mm Inside the body detecting units mounted board assembly PDGG-01, in which there are all the elements of detection units to provide seismic detection units, resistance to sinusoidal vibrations and mechanical shocks board assembly PDGG-01 mounted on a special ball-spring retainer (shock absorbers). The detection unit during operation is fastened to the vertical surface (the wall beam structure, etc.) with the holder. For convenience of mounting of the detecting unit in the facility, with the detecting unit may be provided connecting box-RNC signaling unit 29 or CIC-17. Connecting box-RNC signaling unit 29 and BIC 17 provides connection to the cable connection without connectors spring terminal connectors on the desoldering obekte.V signaling block BIC-17 and a connecting box 29, the RNC-set elements, providing fulfillment of the requirements for electromagnetic compatibility (ensure the normal functioning BDMG-detection unit 04 in the electromagnetic environment of medium hardness, the execution group for noise immunity P3 NP 306.5.02 / 3.035.
