Book A Computer coupled Quality Control Procedure for Gamma ray Scintillation Spectrometry

Download or read book A Computer coupled Quality Control Procedure for Gamma ray Scintillation Spectrometry written by D. F. Covell and published by . This book was released on 1966 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term stabilization of instrumental performance is necessary for gamma-ray scintillation spectrometry whether used for nuclear spectroscopy studies or for radionuclide identification and estimation. This requirement is especially important if high-precision measurements are to be made on a routine basis. It is proposed to achieve sufficient stabilization through statistical quality control, a technique used to maintain the quality of output of a process or system. A quality control procedure was devised which consists of periodic measurement of a current standard spectrum and comparison of it, on a channel-by-channel basis on a computer, with a reference standard spectrum. Significant differences between the two spectra are interpreted as machine deviations that require correction. As part of the procedure, values obtained from this measurement are charted so that current and past performance can be compared easily. This makes possible a prompt awareness of unusual changes in performance. Application of the technique has resulted in improved stability, improved reliability, and reduced maintenance. Approximately 20 minutes of technician time are required per day to apply this procedure to a single instrument. Less time per instrument is required when several instruments are simultaneously controlled. (Author).

Book Computer Correction for Shifts in Gain and Baseline in Gamma ray Scintillation Pulse Height Spectra

Download or read book Computer Correction for Shifts in Gain and Baseline in Gamma ray Scintillation Pulse Height Spectra written by David F. Covell and published by . This book was released on 1965 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quantitative analysis of multicomponent pulse height spectral data, precision depends upon (1) the statistical variation inherent in the radioactive decay process, (2) statistical variations in the detection process, and (3) 9nstrumental variations. The nature of the statistical variations in categories 1 and 2 are well understood and easily considered in the estimation problem. Category 3 variations are more difficult to evaluate and correct. The main variations observed in this category are of gain and baseline. In order to determine the instrumental conditions that prevail at the time of measurement, the spectrum of a standard Ti-44 was obtained immediately before experimental spectra were obtained. This standard spectrum was then compared to a reference standard spectrum to obtain estimates of gain and baseline status, and appropriate corrections were applied to the experimental data. This technique, which can correct for shifts in both baseline and gain in excess of one channel (with respect to channel 256 of a 256-channel system), is capable of making corrections of as little as 1/20 of a channel. Improvement in the resultant quantitative estimation of the constituents of multicomponent pulse height spectra is demonstrated. The method should provide the basis of a good quality control procedure for the scintillation gamma spectrometer, provided the spectrometer data can be conveniently entered into a computer.
