XY-800 low background alpha beta measuring instrument for radiation protection and environmental sample detection

Description :

　　XY-800 low background alpha beta measuring instrument for radiation protection and environmental sample detection

　　XY-800 low background alpha beta measuring instrument for radiation protection and environmental sample detection

　　The injection device of XY-800 low background alpha beta measuring instrument is a single channel type, which can measure separately or provide measurement results simultaneously; Provide the total alpha and total beta activity concentration values in the sample separately. This instrument includes measurement software, with the measurement program translated into Chinese. The operation process has Chinese prompts, and the measurement process is automatically completed and the measurement results can be printed.

　　This instrument is suitable for measuring total alpha and total beta in fields such as radiation protection, environmental samples, medicine and health, agricultural science, import and export commodity inspection, geological exploration, nuclear power plants, water companies, third-party testing, and scientific research institutions.

　　Main technical parameters：

　　1、 Instrument background and detection efficiency

　　· When the 2 π efficiency ratio of 90Sr-90Y β source (active surface diameter Φ 20mm) is ≥ 62%, the background is ≤ 0.1cm-2min -;

　　· When the 2 π efficiency ratio of 239Pu α source (active surface diameter Φ 30mm) is ≥ 85%, the background is ≤ 0.002cm-2min-1;

　　2、 Efficiency stability

　　· The instrument continuously measures for 24 hours, and the detection efficiency changes by α<2% and β<3%;

　　3、 Crossroad ratio

　　· The count ratio of alpha entering the beta tract is less than 1% (for 239Pu),

　　· The count ratio of β entering the α channel is less than 0.3% (for 90Sr-90Y);

　　4、 Detection range

　　α≥5×10-5Bq β≥1×10-6 Bq

　　5、 Usage environment

　　· Insulation resistance>1500V;

　　· Insulation resistance ≥ 2M Ω;

　　· Power supply: AC 220V (± 10%), 50Hz;

　　· Environmental temperature: 0 ℃ to 40 ℃ (± 2 ℃);

　　· Relative humidity:<90% (+30 ℃).

　　Instrument features:

　　1. The material used in the lead chamber of the instrument is old lead, which has the advantages of high density, better shielding performance than new lead, and low background;

　　2. The dual flash instrument adopts imported brands, with high efficiency and good stability;

　　3. The instrument system has been upgraded to an automatic voltage control device, which can effectively protect the main components of the instrument from damage when the current is unstable during use;

　　4. After upgrading the software and hardware of the instrument, the compatibility is better, the measurement data is more stable, and the efficiency is higher;
