Radiation Portal Monitor System

 

Radiation Portal Monitor System

professional security solutions as our significant characteristics to stand out from the industry.
EI-RDV1 is the latest technology radiation detector which can detect and give alarm to radiation threats hidden in the trucks or the cargo
on the trucks. This products are widely used in the railways, seaport, custom, renewable sources factories etc. It is smart security
solution for radiation materials control
 
 
Technical features:
 
1, BIN (Background Identification of Normal) background ignore technology
The technology can quickly detect low-level artificial radioactive materials at high speed in the case of high radiation background, and
the detection time limit can reach 1.05 times of the background radiation level, and the detection time can reach 100 milliseconds;
Detection of radioactive materials in the case of rapid movement is suitable for rapid detection; at the same time, it can ensure that the
equipment will not be falsely alarmed due to the sharp increase of the background; and it can cause the background caused by natural
radiation shielding when the vehicle is occupied. The counting is reduced to compensate, which increases the authenticity of the test
results and improves the probability of detection, especially for weak radioactivity detection;
2, MCA multi-channel energy spectrum analyzer
A large-volume sodium iodide detector equipped with a multi-channel energy spectrum analyzer can perform 1024 channels of analysis
on the radioactive source, and accurately report the type of nuclide in a minimum of 1 second; "This function is sensitive to nuclear
material for defense needs." Check out has outstanding contributions";
3, Feature SIGMA statistical algorithm
Through the feature SIGMA algorithm, the user can easily adjust the detection sensitivity of the device and the probability of false
positives. It can improve the sensitivity to detect very weak radioactive sources (such as loss of radioactive sources) when needed, or
prevent it during long-term online monitoring. Equipment false positives, so that it can be retracted freely;
4, Long life 3He neutron proportional counter
The conventional 3He counter has a life expectancy of about 1011 counts. Our company uses long-life detectors to count up to 1017
counts and increase the detector usage time by a million times. It is suitable for long-term in-line radiation monitoring and high-radiation
fields. jobs;
 
5, NORM rejection function (K40)
This function is used to determine natural radioactive materials (K40). For example, combined with sodium iodide detector and MCA
multi-channel energy spectrum analyzer, it can accurately distinguish medical nuclide, industrial nuclide and natural radionuclide.
6, GIS Geographic Information System
The advanced GIS map system can accurately locate the installation points of the equipment, and allows the data (excluding the
spectrum data) to be transmitted to the monitoring center in real time to achieve centralized control;
7, high-speed sampling, real-time background
The sampling frequency is 100ms, allowing the vehicle to pass quickly; the background is updated in real time every 1 minute to
ensure the accuracy of the test results;
