Product Introduction
The NT-L15 channel type radioactive monitoring system for luggage is independently developed and produced by Shanghai Minghe Instrument Co., Ltd. It is mainly installed at important entrances and exits such as airports, docks, train stations, banks, entry and exit security channels, nuclear power plant control areas, nuclear waste treatment plants, government agencies, etc. It is used to monitor whether pedestrians and packages carry radioactive substances. The product has high sensitivity, wide detection range, short response time, and can achieve advanced functions such as automatic radiation alarm, automatic data storage, automatic capture of on-site photos, and remote data management. When the radioactive level inside pedestrians or packages exceeds the alarm threshold, the system emits an audible and visual alarm signal to prevent the spread of radioactive substances and their pollutants.
Technical Indicators:
-Detector: Imported plastic scintillator detector, with a single detector volume of 15L, comes standard with one, equipped with five sided lead shielding to reduce false alarm rate;
-Energy range: 20keV~3MeV;
-Detection area height: 0.1~1.5m;
-Detection area response width: 1m;
-Allow high speed through luggage: 1.2m/s;
-Environmental adaptability: Temperature: -30 ℃~+60 ℃, Humidity: 30%~95% Rh;
-Distinguish between natural radioactive materials and special nuclear materials;
-False alarm rate: ≤ 1/10000;
-Detection sensitivity: At a background level of 0.2 μ Sv/h, an increase of 0.04 μ Sv/h will trigger an alarm within 1 second; Detection probability 99.9%;
-Detection limit:<100nSv/h;
-Automatic background deduction;
-Modular design, easy to disassemble, expand, customize, and maintain; Strong anti-interference ability, able to work in harsh natural environments;
-Alarm method: sound and light alarm;
-Real time visualization of the screen displaying the passage of packages;
-Power supply mode: 220V/50Hz AC power;
-Protection level: IP55.
