Product introduction
The LB series plastic flash αβ measuring instrument has (1-c6 channels) independent low background αβ main detectors, which can measure multiple samples at the same time, and give the measurement of the total α and total β activity concentration in each sample respectively. It has the characteristics of high sensitivity, low background, simple structure, convenient operation, stability and reliability.
LB series low background αβ measuring instrument can be used for the measurement of the total activity of αβ in the fields of radiation protection, environmental samples, drinking water, medicine and health, agricultural science, nuclear power plants, reactors, isotope production, geological exploration and so on. It can also be used to measure the specific activity of total alpha and total beta activity in polluted water, air, food and soil in nuclear battlefields and nuclear explosion sites.
Technical parameters
• Main detector: The main detector of the instrument is composed of a 45mm diameter HND-DS2 low-background αβ scintillator and a CR105 low-noise photomultiplier tube.
• Scintillator area: 15.896cm2 (Φ45mm). Low background αβ scintillators have high detection efficiency for αβ particles and low background. The CR105 photomultiplier tube is provided with positive high voltage by the high voltage power supply of the instrument.
• Sample tray: made of 0.5mm stainless steel dish, 2mm deep and 45mm in diameter. Sample tray for solid sample measurements.
• When the 2π detection efficiency ratio of the instrument for 90Sr-90Yβ source (active area Φ20mm) is ≥60%, the background is ≤0.10cm-2min-1;
• When the 2π efficiency ratio of the instrument to the 239Puα source (active area Φ30mm) is ≥85%, the background ≤0.002cm-2min-1;
• α/β crossover performance: the count ratio of α into β channel <1% (for 239Pu), the count ratio of β into α channel <0.3% (for 90Sr-90Y);
• Long-term stability:
Repeatability: The instrument is continuously powered on for 24 hours, and the detection efficiency changes α<2%, β<2.5%;
Background stability: During the 24-hour measurement period, the background count change should be within the range of (Nb±3σ), where Nb is the average value of the background count, and σ is the standard error of the background count.
• Instrument sensitivity: α≥5×10-5Bq; β≥1×10-6Bq
• Dielectric insulation > 1500V;
• Insulation resistance ≥ 2MΩ;
Conditions of Use
• Power supply voltage: AC 220V±10%; 50Hz;
• Ambient temperature: 0～350C±20C;
• Relative humidity: <85% (+300C).
Work method
• Can measure αβ at the same time, or measure α or β separately;
• The measurement process and measurement results can be displayed on the monitor, and the results can be printed;
• Measurement time, alpha threshold of the detector, beta low threshold (βL), beta high threshold (β
H) and high pressure can be adjusted by computer according to requirements.
