Monitoring of Radioactive Material Capture in Slovakia: 2003 Contamination Incidents

DESCRIPTION

In 2003, multiple incidents of radioactive material capture were documented in Slovakia, primarily in U.S. Steel Košice. Measurements of radionuclide dose rates were recorded at various locations, including contaminated wagons and metal scrap. Key isotopes involved were Cobalt-60 and Cesium-137, showing radiation levels ranging from nanotesla to microseiverts per hour. The Regional Public Health Authority (RPHA) and HUMA-LAB APEKO were involved in the assessment and control of these materials. This report highlights the importance of monitoring and managing radioactive contamination in industrial settings.
