Low background alpha beta measuring instrument price LB-I

The LB-I series low background alpha beta measuring instrument is a computer-controlled single channel anti coincidence low background alpha beta measuring system. Meet the hygiene standards for drinking water GB5749-2006 for testing the total alpha and beta radioactivity indicators. The instrument adopts programmable high voltage and programmable threshold, and the measurement process is automatically controlled by the computer. The results and raw data can be printed; It has the characteristics of low background, good long-term stability, and easy operation. Meets the secondary standard of GB/T11682-2008.

Low background alpha beta measuring instruments can be used for measuring the total activity of alpha beta in fields such as radiation protection, environmental samples, drinking water, medicine and health, agricultural science, nuclear power plants, reactors, isotope production, geological exploration, higher education institutions, and scientific research. Meet the hygiene standards for drinking water GB5749-2006 for testing the total alpha and beta radioactivity indicators.

Main users of the product: Inspection departments or radiation health departments of disease control centers at all levels, water quality testing centers of water companies, product quality supervision and inspection units, entry-exit inspection and quarantine bureaus, environmental monitoring stations, environmental engineering laboratories of higher education institutions, etc. for measuring the total alpha and beta specific activity.

Specification

When the detection efficiency ratio of the instrument for the 90Sr-90Y source is ≥ 55%, the background is ≤ 0.15cm-2min-1;

When the 2 πα efficiency ratio of the instrument for the 239Pu source is ≥ 82%, the background is ≤ 0.005cm-2min-1;

α/β crossover performance: α →β<1%, β →α<0.5%;

Long term stability and efficiency stability: When the instrument is continuously powered on for 24 hours, the detector efficiency change α is less than<3%, β＜5%；

Background stability: Within 24 hours of measurement, the background count changes in accordance with statistical rules.

Product Features

High degree of programmable control: The instrument adopts programmable high voltage and threshold, and the measurement process is automatically controlled by the computer. The results and raw data can be printed;

Innovative lead chamber structure: The lead chamber structure design reduces the distance between the anti coincidence detector and the main detector, resulting in low background and anti coincidence. The technical indicators of the LB-I low background alpha beta measuring instrument have reached the domestic level.

The instrument has long-term stability and good repeatability.

The scintillator used for the main detector probe is a low background alpha beta scintillator, which is made by special processing. It detects alpha beta with a low background, has a washable surface, is not afraid of deliquescence, and is not easily damaged.
