Product Description
DA Series Air Flow type Alpha-Beta Low-Level Counter
Product Overview
The DA Series (1-8 channels) Low-Level α/β Counter is a precision instrument designed for measuring low-level alpha and beta radioactive intensity. This versatile equipment is suitable for measuring total α and total β radioactivity in various samples including water, soil, building materials, ores, aerosols, and food. It serves radiation protection, environmental protection departments, medical facilities, biological research, agricultural applications, scientific research institutes, and educational institutions.
The instrument is available in four models: DA-101, DA-102, DA-104, and DA-108, and meets the verification requirements of JJG1100-2014 air flow proportional counter total α and total β measuring instrument.
Key Features
- Low background count with high particle detection efficiency
- Utilizes thin-window gas-flow proportional counter tube as detector
- Counter coincidence between shielded and measurement counter tubes reduces environmental radioactivity interference
- Detection efficiency for 14C low-energy β-rays ≥40%
- Superior performance compared to semiconductor and scintillator-based detectors
- Gas flow proportional counter tube window mass thickness: ~2μg/cm²
- Measurement window area: Ø60mm with sample area: Ø55mm
- Includes PC application software for parameter configuration
- Simple operation interface with independent channel operation and calculation
- Direct measurement of radioactive specific activity in Bq/L or Bq/Kg
