Low bottom α / β radioactive measuring instrument FN

Use The FN series (1-8) low fundamental α / β detector is a precision instrument for measuring a low level α, β radioactivity. It can be used in total α, total ore, gas-sol, food, etc., total β radioactive measurement; suitable for radiation protection, environmental protection sector, medical, biological, agriculture, research institutes and colleges and universities Horizontal α / β radioactivity measurement. The instrument is a series of products, 5 types: Fn-01, Fn-02, Fn-04, Fn-06, Fn-08. The instrument satisfies the total α of JJG1100-2014 orthopedic ratio counter, total β measuring instrument. Low bottom radioactivity test laboratory Performance characteristics ■ Very low fund counts is relatively high particle detection efficiency; ■ Tube tube with large-area thin window gas is detector, with specialized screen The mandatory ratio is in line with the measurement count tube to reduce the surrounding environmental radioactivity Interference on the measurement; ■ The detection efficiency of 14C low energy β rays is ≥40%; better than the semiconductor, the scintillator is The same detector of the probe. ■ Ultra-thin window, gas-based proportional count of the quality thickness of the row window ~ 2μg / cm-2, measure The area of ​​the volume is Ø60mm, the sample area is Ø55mm. ■ Advanced computer application, high voltage, and domain value all computer settings. Human operation Interface, each channel can work independently, independently; you can get it directly The radioactive ratio of the sample BQ / L or BQ / KG, etc. Low bottom radioactivity detector Software interface
