| Abstract | This report describes in detail the principal characteristics of the NRC Fricke system. The procedure for making the Fricke solution and a description of the Millipore water system are included. Fricke solutions are irradiated in pancake shaped quartz vials and the readouts are done in Hellma quartz spectrophotometer cuvettes. The cleaning and filling of the vials, the cuvettes, and all other glassware is described since cleanliness is a very important factor in attaining good precision. The absorbance is read using a Varian model Cary 400 UV-Vis spectrophotometer equipped with a high performance R928 photomultiplier tube and a specially designed sample holder. The modifications to the Cary 400 are described in detail. Software, in Application Development Language (ADL), was developed to control the readouts of the Fricke samples. The absorbance readouts of the irradiated samples are discussed, especially as they apply to measurements of absorbed dose (⁶⁰Co γ-rays) in the range 5-25 Gy. The standard uncertainty on the mean of a set of eight such measurements is normally between 0.05% and 0.15%. Some results showing the stability and reproducibility of the Fricke system are presented. Safety issues associated with the handling and use of the Fricke solution are outlined |
