1. 1. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Patrik Dahlström; [2022]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER

3. 2. Calculating Minimum Detectable Activity for a moving scintillator detector using real-time speed measurement : Implementing a monitoring system to improve accuracy of surface contamination measurement systems

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Artur Amcoff; Oscar Persson; [2021]
   Nyckelord :Minimum Detectable Activity MDA ; Surface contamination; ISO 11929; Alpha α radiation; Beta β radiation; Detection limit; Counting efficiency; Minsta detekterbara aktivitet; Ytkontaminering; ISO 11929; Alfa α strålning; Beta β strålning; Detektionsgräns; Radioaktiv mäteffektivitet;

   Sammanfattning : Surface contamination occurs in nuclear facilities, something that is important to detect easily and efficiently. Using today’s methods to detect nuclear surface contamination may cause certain inconsistencies as the human operator is solely trusted to keep the detector at the correct distance and move it at the correct speed.
