Özet

In recent years, there is a variety of radiation detection in the market deployed in situ and are used for radionuclide categorization as well Special Nuclear Material (SNM) categorization for nuclear security purposes. However, it is a very vital matter to know which of these RIID devices should be used for what purposes and determine measurement capabilities . In this context, the determination of 235U enrichment of depleted, low enriched uranium(LEU) and high enriched uranium (HEU), Reactror grade Plutonium(RGPu) or Weapon Grade Plutonium(WGPu), U-233, Np-237 samples is a prerequisite to prevent illicit trafficking of nuclear materials. Hence, in-situ measurements have great importance for first responders or FLOs. In ideal case, they need to use a robust, temperature stabilized but also having good energy resolution detectors to get more accurate results for isotope identification(ID) and nuclear material categorization such as SNM, NORM, Medical, Industrial and the other isotopes. However, this is not practical due to technical capabilities of RIIDs and environmental affecting factors.
