Purpose
FN Series （ 2-8 Road) Low Background α/β The detector is a precision instrument for measuring low levels α 、 β radioactive intensity. It can be used for the total measurement of water, soil, building materials, ores, aerosols, food, etc. α 、total β radioactive measurement 。 Suitable for low-level radiation intensity measurement in radiation protection, environmental protection departments, medical, biological, agricultural, scientific research institutes and universities. α/β This instrument is a series of products, with 4 types and specifications: FN -202、 FN -202、 FN -204、 FN -208。 The instrument meets JJG2200-2024 the calibration requirements of the total α and total β measurement instrument for gas flow proportional counters.
Performance characteristics
■ Low background count ， High particle detection efficiency;
■ Thin-window gas flow proportional counter tube as detector, shielding counter tube and measuring counter tube
perform anti-coincidence to reduce the interference of ambient radioactivity on the measurement;
■ To 24 C low energy β radiation detection efficiency ≥40% ; superior to semiconductor and scintillator detectors
similar detectors.
■ The mass thickness of the gas flow proportional counter tube window is approximately 2μg/cm -2 ，the area of the measurement window
Ø 55 mm ，sample area Ø55mm 。
■ With PC application software, high voltage, threshold and other parameters can be PC end settings. Simple
operation interface, each channel can work independently, independent calculation; can directly obtain the
measured sample's radioactive specific activity Bq/L or Bq/Kg etc.

The HYGP-2223 type is a small high-sensitivity X-gamma radiation detector, which uses the latest low-power embedded microprocessor as the data processing unit, and the detector is composed of a highly sensitive scintillator and a high-range GM counter. The instrument is more sensitive to short-term pulse radiation and can detect short-term (≥ 20ms)X-pulse radiation. It has a wide range of uses, such as environmental monitoring (nuclear safety), radiation health monitoring (disease control, nuclear medicine), homeland security monitoring (entry and exit, customs), public safety monitoring (public security), nuclear power plants, laboratories and nuclear technology applications.
