Quality Assurance in Nuclear Medicine Radioactivity Measurements
The paper presents some recent results of the Radionuclide Metrology Laboratory (RML) from IFIN-HH, in the assurance of quality in radioactivity measurements for nuclear medicine. Three aspects are treated: (i) Participation of the RML in the frame of the IAEA Coordinated Research Program (CRP), E 2.10.05; (ii) Improvement of the secondary standard, based on a CENTRONIC IG12/20A ionization cham...
متن کاملModels for Conductance Measurements in Quality Assurance of Water Analysis
Models for the prediction of conductance in nonbrine water samples through the measurement of ionic concentrations and other parameters are compared. Such predictions are often used for quality assurance purposes by comparing them with actual measurements to determine whether gross analysis errors have been made. A currently recommended method for making such predictions is a semiempirical rela...
متن کاملQuality assurance of the Brewer UV measurements in Finland
The quality assurance of the two Brewer spectrophotometers of the Finnish Meteorological Institute is discussed in this paper. The complete data processing chain from raw signal to high quality spectra is presented. The quality assurance includes daily maintenance, laboratory characterizations, calculation of long term spectral respon-5 sivity, data processing and quality assessment. The cosine...
متن کاملA Calibration and Quality Assurance Program for Environmental Radon Measurements
The ideal facility for assessing the quality of radon measurements at environmental levels consists of: (1) an instrument whose response to radon and its progeny is determined from measurements of a certified or standard 226Ra source, and (2) a calibration room with a known radon concentration. The linkage between these two elements and additional quality control requirements are discussed here...
متن کاملQuality Assurance Whose Quality and Whose Assurance?
Government involvement in quality assurance is becoming the trend in many countries, including New Zealand. What values underpin the systems that evolve in each country, and who has given legitimacy to them? In the context of the prevailing ideology of early childhood, this paper unpacks quality assurance in Australia and comments on the assumptions, taken for granted premises and values which ...
