Solid standards for quality control in radiochemical analysis
- Idaho National Engineering Lab., Idaho Falls, ID (United States)
The accuracy of radiochemical analyses is frequently determined by intercomparison of results obtained by several participating laboratories on a given set of samples. From the large variability in the results generally obtained, it is evident that at least some of the results are inaccurate. When large numbers of laboratories are involved, with little if any discernible improvement from one intercomparison to another, the seriousness of the matter becomes obvious. Examples from the literature are discussed. Easy availability of standard samples containing known quantities of any radionuclide of interest would permit each individual laboratory to assess its own internal performance at any frequency desired without assistance from others. The advantages of preparing the standards by addition of known activities of the radionuclides to natural matrices rather than using standards with the nuclide of interest already in place by natural means are discussed.
