Russia masters production technology of ultra-pure germanium for gamma detectors
The Giredmet Research Institute, part of Rosatom, recently announced that its researchers have developed technology for producing high-purity germanium (HPGe) for gamma-ray detectors. This breakthrough is expected to replace imported crystals and promote the formation of a complete production cycle for detector equipment within Russia. According to reports, experts at Giredmet have designed and manufactured experimental equipment, and based on this, developed a process for preparing ultra-high-purity germanium single crystals. The purity of the germanium material reaches at least 7N, i.e., 99.99999%, equivalent to only one impurity atom per 10 million atoms of the primary material. The institute stated that the first batch of experimental samples has been obtained, verifying the effectiveness of the adopted deep germanium purification method in achieving the purity level required for detector applications.

Automatic Radiation Environment Monitoring Station in Mianyang, Sichuan Put into Trial Operation, with Core Equipment and Systems Achieving Domestic Localization
Recently, the automatic radiation environment monitoring station located within the Nuclear Medical Health Industrial Park of the China (Mianyang) Science and Technology City was officially put into trial operation. As the first automatic radiation environment monitoring station in Sichuan Province to fully achieve domestic localization of core equipment and systems, it will provide radiation environment safety assurance for the development of the nuclear medical industry in the park through 24-hour uninterrupted automatic monitoring capabilities. At the automatic radiation environment monitoring station, operational data from equipment such as environmental γ dose rate monitors are updated in real time on monitoring screens. Compared with the previous approach that relied on manual on-site sampling and batch laboratory analysis, the automatic station enables continuous monitoring, reducing the time required to produce monitoring results from several days to the same day, thereby improving...
