Beijing Zhongzhi Nuclear Safety Technology Co., Ltd. is a high-tech enterprise that integrates research and development, production, technical consulting, and sales of nuclear instruments. The foundation of the company's establishment is GAMCALIBA passive efficiency calibration software, a new generation of automatic HPGe detector energy spectrum analysis software, NaI radioactivity measurement system, and LaBr3 spectrometer, which have a wide influence in the field of radioactive measurement. The core capability of the enterprise is energy spectrum measurement and analysis, and the company's gamma spectrum analysis capability is internationally advanced. Since its establishment, the company has rapidly launched high-end nuclear radiation detection equipment with international leading level: laboratory HPGe gamma spectrometer; Anti Kang and anti Universe HPGe gamma spectrometer; Laboratory and portable NaI and LaBr3 spectrometers, handheld nuclide identifier; High resolution CZT spectrometer; Unmanned aerial vehicle radioactive aerial survey system radioactive nuclide concentration measuring instrument; Food gamma radioactivity measuring instrument; Underwater radioactive source search and activity measurement instrument, radioactive field measurement instrument; Whole body counter, etc. In terms of core capabilities, the company has made significant breakthroughs: it has developed and produced the first commercial anti health and anti universe high-purity germanium gamma spectrometer in China; Real time online monitoring of artificial radioactive nuclides in millibecquerels per cubic meter of air was achieved using scintillation detectors; The online anti Compton measurement system for primary fuel element damage, developed and tested in nuclear power plants, is the only online anti Kang primary activity measurement system in the world and has won great reputation for the company; The passive efficiency calibration activity measurement of CZT detector has been achieved, greatly expanding the on-site measurement capability of CZT detector. Beijing Zhongzhi Nuclear Safety Technology Co., Ltd. has a sound organizational structure, including hardware department, software department, finance and administration department. Each department cooperates sincerely and has achieved great success in product research and development. The company has passed ISO9001 quality system certification, been recognized as a dual soft enterprise and rated as a high-tech enterprise in Zhongguancun. It is a qualified supplier of China National Nuclear Corporation and China General Nuclear Corporation. The company's vision is to become a high-end nuclear instrument for national brands. In the future, Zhongzhi Nuclear Safety will focus on the localization of high-end nuclear instruments and strive to make greater contributions to the development of the country's nuclear industry. The company's current core products mainly include: NaI spectrometer, LaBr3 spectrometer, and high-purity germanium spectrometer. Our company's unmanned aerial vehicle spectrometer has been used in the China North Korea border project of the Ministry of Environmental Protection, and has won three consecutive bids for spectrometer equipment. Currently, there is still a certain gap between other domestic manufacturers' unmanned aerial vehicle spectrometers and ours. The NaI spectrometer is currently the product with the highest sensitivity for identifying gamma radioactive isotopes among similar products in China. Due to the use of time series analysis, fuzzy clustering, and energy spectrum analysis techniques in its nuclide identification software, the sensitivity of nuclide identification has been improved by orders of magnitude compared to similar products at home and abroad. Zhongzhi Nuclear Safety is the third high-purity germanium equipment supplier in China, after ORTEC and Canberra, to provide a complete and mature series of high-purity germanium equipment. Our company has long-term strategic cooperation with BSI, and has appointed agents and after-sales service providers for BSI in Chinese Mainland.
