With the rapid development of nuclear medicine and molecular imaging technology in my country, the stability of the radionuclide supply chain and nuclear drug quality control capabilities have increasingly become the focus of the industry. Tianjin Heyao Technology Co., Ltd. relies on the industrial resources of its parent company Jieqiang Equipment to officially launch a full range of radionuclide distribution and calibration source service systems covering medical, industrial, environmental protection and scientific research fields.

Calibration source: Meets the calibration needs of many types of equipment such as gamma spectrometers, liquid scintillation, and activity meters.

Heyao Technology can provide standard radioactive sources in various forms such as point source, area source, solution source, powder source and customized source. Among them, the α/β area source uses high-purity aluminum sheets or stainless steel sheets as carriers. The radionuclides are evenly fixed through electroplating, anodizing filling and other methods. The surface is covered with a very thin protective film. It is mainly used for scale surface contamination meters, large-area radiation detectors and other equipment.

The radioactive standard solution uses aqueous solution, organic solution or suspension as the carrier, and the nuclides are evenly distributed. It can be used to determine the detection efficiency and energy response of gamma spectrometers, liquid scintillation counters and activity meters.

Powder reference materials use artificial inert matrices such as alumina, silica, cellulose, and polytetrafluoroethylene micropowder, and are sealed in bottles or pressed into tablets. They are suitable for the calibration of alpha spectrometers, low-background alpha/beta counters, and gas flow counters.

Customized standard source: simulate real scenarios to support nuclear emergency and environmental monitoring

For special application scenarios, Heyao Technology provides iodine box standard sources, aerosol standard sources, soil standard materials and bioash/plant ash standard materials. The iodine box standard source uses activated carbon or molecular sieve as the adsorption matrix to encapsulate iodine-131, iodine-129 and other nuclides. It is a key standard material for nuclear emergency iodine monitoring. The aerosol standard source deposits cesium-137, plutonium-239, etc. on the filter membrane, which is used for the efficiency scale of the aerosol sampler and α/β counter. Soil and bioash standard materials are mixed with cesium-137, strontium-90, polonium-210 and other nuclides to facilitate the verification of environmental radioactivity analysis methods and the quality control of biological monitoring after nuclear accidents.

Full-chain nuclear drug quality control technical services

Heyao Technology provides radionuclide traceability, purity analysis, radiopharmaceutical quality research and registration technical services to help customers meet regulatory requirements throughout the entire process from research and development to clinical application. The company plans to establish a complete nuclear medicine quality control laboratory equipped with advanced analytical instruments such as high-performance liquid chromatography, gamma spectrometer, and liquid scintillation counter.

Radiation environment safety assessment and protection

The company also carries out the overall measurement and calibration of radiation environment automatic monitoring stations, nuclear radiation environment safety assessment, protective equipment supply and safety consulting services, providing professional support for the nuclear industry, environmental protection, disease control and other industries.

Taking nuclear safety as the bottom line and promoting high-quality development of the industry

Heyao Technology stated that it will always adhere to the principle of "strict prudence, meticulousness, and foolproofness", adhere to the nuclear safety red line, and use technological innovation and full-process control to protect the steady and long-term development of the nuclear medicine and nuclear technology application industry.
