Balakovo NPP Publishes 2025 Ecological Safety Report

Russia's Balakovo NPP released its 2025 ecological safety report on August 31, 2026. The report data show that the plant's operational activities comply with the requirements of sanitary, epidemiological, and environmental protection regulations. The report was presented in a roundtable format. Participants learned about the plant's ecological policy and the results of environmental monitoring studies, and exchanged views on relevant issues. Alexander Kurlov, head of the external radiation safety laboratory at Balakovo NPP, stated that before the plant's construction, the natural gamma background of the local area had to be measured and its upper and lower limits determined. Since the plant was put into operation, no exceedances of these limits have been recorded at the industrial site or in the surrounding areas.

Finland's 2025 Environmental Radiation Monitoring Shows No Harmful Effects from Nuclear Power Plant Operations

The 2025 environmental radiation monitoring results released recently by the Radiation and Nuclear Safety Authority of Finland (STUK) show that radioactive substance levels in the Finnish environment generally remained low, and the operation of the Loviisa and Olkiluoto nuclear power plants has not caused harmful radiation impacts on the public or the environment. STUK continuously tracks Finland's radiation situation through its environmental radiation monitoring program. The monitoring includes continuous measurement of external radiation, as well as monitoring of radioactive substances in air, radioactive fallout, water bodies, food, and the human body, with the aim of promptly detecting changes in radiation levels and confirming the safety of the living environment. Finland's automatic external radiation monitoring network covers essentially the entire country. In 2025, 255 monitoring...
