Long-term radiation environment at Kola NPP remains under control: gamma dose rates within natural background levels, 15 permanent observation stations operating since 1972

Long-term monitoring results from the external radiation monitoring group at Russia's Kola Nuclear Power Plant show that gamma radiation dose rates around the plant site have consistently remained within natural background radiation levels, with radionuclide concentrations matching background values, indicating a sound radiation environment with no differences from surrounding areas. The station's radiation safety department collects surface water samples from the discharge canal monthly, with monitoring coverage encompassing all elements including the atmosphere, snow cover, bottom sediments, food products, algae, berries, mushrooms, and caged fish. The monitoring architecture consists of two tiers: 15 permanent environmental observation stations have been in continuous operation since before the commissioning of the first reactor unit in 1972; 13 ASKRO automated radiation environment monitoring system stations provide real-time ground-level gamma dose rate data, which is transmitted directly to the Rosenergoatom crisis center and integrated into the national unified radiation monitoring network. Approximately 200,000 cubic meters of air are drawn weekly through air filtration units to capture radionuclides, with volumetric activity of radioactive iodine also measured. A mobile radiological laboratory performs on-site spectrometric analysis. Annually, about 1,200 environmental samples are collected from around the plant site and delivered to the Polyarnye Zori laboratory, where well water samples analyzed by Canberra spectrometers yield "zero nuclide" results, with samples retained for one year for potential re-analysis. Biological samples are processed using the ashing method, and instrument sensitivity is sometimes insufficient to even detect any signal from the plant's impact.

Maistop Completes Pre-A Round Financing to Advance Medical Radionuclide Industrialization via Electron Accelerator Method

August 12 news, Xi'an Maistop Technology Co., Ltd. recently completed its Pre-A round of financing, with investors including the Central Enterprise Strategic Emerging Fund and Guoxin Venture Capital Fund, both under China Reform Holdings Corporation. The proceeds from this round will primarily be used for site construction, equipment procurement, technology R&D, and daily operations. Founded in 2019, Maistop is a technology enterprise engaged in the R&D and production of medical radionuclides as well as nuclear medicine technical services. The company focuses on the preparation of medical radionuclides via the electron accelerator photonuclear reaction method, with core products including Actinium-225, Lead-212, Copper-67, and Molybdenum-99. Among these, Actinium-225 is a scarce radionuclide of significant interest in alpha-emitting nuclide targeted therapy, with relatively strong global clinical demand...
