Target (Shanghai) Technology Co., Ltd. recently released a new BN-60 series low background alpha and beta measuring instrument, which is mainly used in environmental samples, radiation protection, medicine and health, agricultural science, import and export commodity inspection, geological exploration, nuclear power plants and other fields. This instrument can accurately measure the total alpha and beta in media such as water, biological samples, aerosols, food, medicine, soil, rocks, etc.
The BN-60 series low background alpha and beta measuring instrument adopts advanced zinc sulfide+plastic flash detectors, with two, four, six, and eight detector options available. Its detection efficiency*High, the 2 π efficiency of 90Sr-90Y β source reaches over 58%, and the 2 π efficiency of 239Pu α source reaches over 90%. Meanwhile, the instrument has an extremely low background count, β≤0.1cm-2min-1，α≤0.01cm-2min-1。
It is worth mentioning that the instrument has*A high cross channel ratio results in a count ratio of<1% (relative to 239Pu) for alpha to beta channels and<0.3% (relative to 90Sr/90Y) for beta to alpha channels, effectively avoiding interference from different types of radioactive materials. At the same time, the instrument also has excellent background stability and efficiency stability. Within 24 hours, the background count changes within the range of (Nb ± 3 σ), and the alpha detection efficiency of each channel changes by ≤ 3%, and the beta detection efficiency of each channel changes by ≤ 5%.
In addition, the shielding thickness of the instrument reaches a thickness of ≥ 80mm, making it easy to disassemble and install, enabling it to work stably in various environments. Its working temperature range is -10 ℃~40 ℃, and the humidity range is 0~95% Rh, allowing it to work normally in various environments.
The BN-60 series low background alpha and beta measuring instruments launched by Target (Shanghai) Technology Co., Ltd. undoubtedly bring new solutions to related fields. Its efficient and stable detection performance, as well as excellent environmental adaptability, will provide great convenience for radioactive measurement work in related fields.
