Criticality accident dosimetry system based on chemical and solid state dosimeters
Ruđer Bošković Institute (RBI) criticality dosimetry system consists of a chemical dosimetry system (developed in RBI) for measuring the total (neutron + gamma) dose, and a thermoluminescent (TL) for a separate determination of the gamma ray component. The dosimeter has been designed as a glass ampoule filled with the chlorobenzene-ethanol-trimethylpentane (CET) solution and inserted into a pen-shaped plastic holder. For dose determination, a newly constructed optoelectronic reader has been used. Doses in the range 0.2-15 Gy can be measured. The RBI teem took part in the International Intercomparison of Criticality Accident Dosimetry Systems at the SILENE Reactor, Valduc, 2002, with the CET dosimetry system and TLD-700 TL detectors. The results for total dose obtained with CET dosimeter showed very good agreement with the reference values. Although the results obtained for gamma ray dose on average were in a good agreement with the reference values, the separate determination of the gamma gay component in a mixed field is still a difficult task and needs improvement. This improvement could be achieved using radiophotoluminescence (RPL) glass dosimetry system. Results of SC-1/FGD-200 RPL dosimetry system testing at RBI are shown.
