monitor radiation MPS-01 "Kordon-MN"
|
IPU-radiative Monitors 01 "Cordon-MH" (hereinafter the monitor) is designed for continuous measurement of the radiation level of the monitored object, comparing the measured values with the background radiation level, signaling the exceeding of the measured values over a background. Registration and analysis of ionizing radiation in the monitor is carried out by comparing the emission from the controlled object from the background radiation levels at the site of the monitor locations without direct measurement of the numerical values which either normalized emission characteristics.
The monitor is used at security checkpoints for various purposes : road, rail and pedestrian border control, PPC nuclear power plants, enterprises of atomic-industrial complex, the metallurgical enterprises, the enterprises for extraction, processing and storage of radioactive and nuclear materials processing facilities and storage of radioactive waste, PPC government agencies, banks, offices etc.
Detection monitor radioactive substances and nuclear materials is given in the form of signals showing that the controlled object radiation exceeds a selected threshold limits with respect to the external background radiation.
Monitor represents It is a stationary device, consisting of a structurally complete blocks:
- radiation detection panel ol with blocks gamma BDPS;
- PRI controllers;
- sensors KBKH object;
- OL radiation panel with neutron detecting units BDPN;
- signaling block BIC;
- BNN supply unit;
-. industrial panel computer PPC
radiation panel gamma completed one of the two detection units BDPS depending on delivery options. Each detection block includes an organic scintillation detector sensitive volume which is 7000 cm3 or 12500 cm3. To reduce the influence of natural gamma background detector with three sides except the front, closed lead shield.
The radiation panels neutron radiation as two neutron detectors are used 3He proportional counters 800 cm3 in volume. The counters are placed in the moderator made of a polyethylene.
An industrial panel computer monitor at the same time can be connected to up to four radiation monitoring portals. Each portal may contain from 2 to 8 radiation panels. Panel computer has the following default ports and interfaces for connecting peripheral equipment:
- two serial RS-232 port;
- parallel port PS / 2;
- USB port;
- Port Mic-in / Line-out;
-. Ethernet 10/100 Base-T
Power panel computer monitor is carried out either by an AC voltage of 135 ... 242 V or DC voltage + 24VDC power supply BNN. In the case of the disappearance of the mains power supply, the monitor automatically switches to power supply from BNN built-in power supply and battery for at least 8 hours performs all its functions. The battery pack is automatically charged when the mains power supply. In an accident the AC power (exceeding the upper voltage threshold) in the BNN unit automatically triggered protection. Restart the power supply is possible only after the elimination of the causes of the accident by briefly pressing the button "Reset relay».
The signaling unit CIC for audible and visual alarm when the monitor alarm. Mounted on the top panel of the radiation of one of the measuring column. The sound pressure level when an alarm is not less than 80 dB at a distance of 1 m.
CBC object sensors designed to detect the presence of an object in the monitored area by crossing the last infrared ray. Are arranged in pairs (receiver - transmitter) in opposite radiation panels measuring columns
At the request of the consumer with the monitor MPS-01 "Kordon-MN" can be turned on a digital video surveillance system "Patriot" ..
radiation Monitors MPS-01 "Kordon-MN" produced in accordance with the specifications TU U 33.2-19310157-017: 2006. Specifications have passed sanitary-hygienic examination and agreed Dnipropetrovsk regional SES (conclusion of the state sanitary-hygienic examination number 9833 of 06.03.2006g.).
