China New Product Portable Dose Rate Meter - RJ12 series channel type pedestrian, line package radiation monitoring equipment – Ergodi Detail:
① The BIN (Background Identification of Normal) background ignores the technology
② MCA multispectrum analyzer, characteristic SIGMA statistical algorithm
③ NORM function (40K) Quick distinguish between common artificial and natural nuclides (e. g40K、232Th)
④ Nuclide recognition function (with sodium iodide probe / optional)
⑤ Combining the sodium iodide detector and the MCA multichannel energy spectrometer analyzer can accurately distinguish between medical nuclides, industrial nuclides, and natural radionuclides

Misalarm rate
In a stable environment:
Use the space sensor, 10000 times, false alarm rate 1
Without using the occupying sensor, the false alarm rate and misidentification rate are used once within 12h
γ Radiation Response
Occupup 50 times, alarm 49 times
outrange
Over 100 v S / h, a high radiation alarm is emitted and removed within 1min after the source leaves
Radiation-induced neutron alarm
No neutron alarm is triggered when the dose rate reaches 100 Sv / h
Background influence
When the background change is large enough to cause a large change in the alarm probability, the monitoring system shall issue a warning prompt
Nuclide recognition
Natural nuclide | 40K、226Ra、232Th |
Industrial nuclide | 241Am、137Cs、60Co、57Co、22Na、133Ba、54Mn、88Y |
Medical nuclides | 131I、201Tl、203Hg、18F、99mTc、99Mo、192Ir |
Special nuclear materials | 57Co、152Eu、238U |
Note: Nuclide identification and neutron detection are optional, not in the standard system
