Introduction
Fang Ji® FJ-X2 series products are equipped with the fourth-generation Cadmium Zinc Telluride (CZT) detectors and Lanthanum Bromide doped Cerium (LaBr₃:Ce) crystals, enabling accurate detection of X-rays, gamma rays, alpha particles and neutrons. Ideal for radiation monitoring of medical X-ray equipment, nuclear work environments, industrial X-ray flaw detection equipment and other scenarios, the products are designed with in-depth integration of industry characteristics and advanced industrial design concepts. Boasting a sleek and aesthetically pleasing appearance, they offer three flexible usage forms: wearable, handheld and modular (supporting user secondary development).

Core features
1. Detect X-rays and gamma rays within the energy range of 30keV~3MeV;
2. Compact size with high detection sensitivity, the dose rate measurement accuracy reaches 0.01μSv/h, with a measurement error of <±20% under ¹³⁷Cs radiation source;
3. Detection response time < 3 seconds;
4. FJ-X2 supports cloud-based data management, which can simultaneously monitor X/γ personal dose rate, blood pressure, heart rate and exercise steps, with personal threshold alarm and visual warning platform;
5. Strong battery life, supporting 60 hours of continuous operation on a single charge;
6. Support Beidou, GPS and LBS positioning (function optional);
7. The LaBr₃:Ce crystal adopted by the handheld neutron detector features high density (5.1 g/cm³), high light yield (70000 photons/MeV), fast decay time (16 ns), high energy resolution (2-3%, currently the inorganic scintillation crystal with the optimal energy resolution performance), excellent energy proportionality and outstanding high-temperature stability;
8. Each product is equipped with a calibration certificate issued by the National Bureau of Metrology, ensuring the authority and reliability of measurement data.
