Technical Performance Specifications
Detector Type: Primary detector is a Lanthanum Bromide (LaBr₃) scintillation detector; secondary detector is an energy-compensated GM detector.
Lanthanum Bromide Scintillation Detector Size: ≥ 1.5 inches.
Dose Rate Range: 100 nSv/h ~ 30 mSv/h.
Energy Response Range: 30 keV ~ 3 MeV (γ-rays).
Energy Resolution: ≤ 3.5% (for Cs-137) (Third-party authoritative institution test report required).
Identification Confidence Level: 70% ~ 100%.
The instrument automatically switches between probes based on the selected ''range'' and provides power-off protection for the probes.
System Spectral Channel Count: 1024 channels.
Storage Capacity: Built-in 16 GB large-capacity memory card capable of storing 400,000 sets of 1024-channel spectral data.
Features battery level monitoring and threshold alarm function.
Power Supply: Built-in 14.8 V lithium-ion rechargeable battery pack (charger included).
Activity Response (R) for Cs-137: 0.16 (x10³) s⁻¹ Bq⁻¹; Activity Response Non-linearity (L): ≤ 12%; Repeatability: ≤ 8% (Activity response for Cs-137 measured at a distance of 15 cm between the detector center and the reference source) (Third-party authoritative institution test report required).
For single radionuclide sources such as Am-241, Cs-137, Co-60, the instrument achieves a 100% identification rate within 60 seconds at a distance of 30 cm behind a 5 mm thick steel plate shield (Third-party authoritative institution test report required).
Ambient Dose Equivalent Rate Response: At 20 mSv/h, the calibration factor is ≤ 1.5 (Third-party authoritative institution test report required).
Capability to identify five or more mixed radionuclides simultaneously in a field (Third-party authoritative institution test report required).
Display: Color touch screen, not smaller than 4 inches (Photograph of actual product required as proof).
Operating Time: > 10 hours.
Dimensions: ≤ 250 mm × 140 mm × 120 mm (L × W × H).
Weight: ≤ 2 kg.
Operating Temperature: -20°C ~ 50°C.
Operating Humidity: ≤ 90% (at 35°C).
Storage Temperature: -50°C ~ +70°C.
Equipped with USB interface.
Source Search Mode: The source search interface simultaneously displays the current CPS value from the detector and a graph of CPS values measured over the previous 60 seconds. An audible buzzer sounds, with shorter intervals as CPS increases. Additionally, when the dose rate exceeds the warning threshold, indicator lights will flash (Photograph or screenshot required to prove functional completeness).
During spectrum measurement, the interface displays detailed spectral data including channel number/count, energy, dose rate, measurement time, cumulative dose, CPS, date, time, and battery level (Photograph or screenshot required to prove functional completeness).
After spectrum measurement is complete, the interface displays identified information such as radionuclide name, type, confidence level, actual count, and recognized count (Photograph or screenshot required to prove functional completeness).
Stored spectral data can be directly viewed on the radionuclide identifier main unit (Photograph or screenshot required to prove functional completeness).
The instrument must comply with the standard ''Electromagnetic Compatibility - Testing and Measurement Techniques - Electrostatic Discharge Immunity Test.'' Proof of passing electrostatic discharge immunity testing must be provided via a copy of a test report issued by an authorized institution.
