The calibration and related measurement services of the National Bureau of Standards are intended to assist the makers and users of precision measuring instruments in achieving the highest possible levels of accuracy, quality, and productivity. NBS offers over 300 different calibration, special test, and measurement assurance services. These services allow customers to directly link their measurement systems to measurement systems and standards maintained by NBS. These services are offered to the public and private organizations alike. They are described in NBS Special Publication (SP) 250, NBS Calibration Services Users Guide. The Users Guide is being supplemented by a number of special publications (designated as the "SP 250 Series") that provide a detailed description of the important features of specific NBS calibration services. These documents provide a description of the: (1) specifications for the service; (2) design philosophy and theory; (3) NBS measurement system; (4) NBS operational procedures; (5) assessment of measurement uncertainty including random and systematic errors and an error budget; and (6) internal quality control procedures used by NBS. These documents will present more detail than can be given in an NBS calibration report, or than is generally allowed in articles in scientific journals. In the past NBS has published such information in a variety of ways. This series will help make this type of information more readily available to the user. This document (SP 250-10), NBS Measurement Services: Radioactivity Calibrations with the "4it" Gamma Ionization Chamber and Other Radioactivity Calibration Capabilities, by J. M. Calhoun, is the tenth to be published in this new series of special publications. It describes the use of the NBS "4tt" gamma ionization chamber to measure the activity of gamma-ray-emitting radionuclides against national standards (see test numbers 43010C and 43020D in the SP 250 Users Guide). It also reviews NBS capabilities for making direct radioactivity calibrations. Inquiries concerning the technical content of this document or the specifications for these services should be directed to the author or one of the technical contacts cited in SP 250. The Center for Radiation Research (CRR) is in the process of publishing 21 documents in this SP 250 series, covering all of the calibration services offered by CRR. A complete listing of these documents can be found inside the back cover. NBS would welcome suggestions on how publications such as these might be made more useful. Suggestions are also welcome concerning the need for new calibration services, special tests, and measurement assurance programs

“…Although the accuracy required and achieved for specifying the activity of a sample of a radionuclide is usually only of one percent, a standard must be developed for each pertinent radionuclide. Currently the National Institute of Standards and Technology has received justified requests for over 130 radionuclides, for example [ 2 ]. There is no official international standard for any radionuclide; rather, the standardizing laboratory in each country develops an appropriate measuring method which would allow a sample of the particular radionuclide to be measured with a known uncertainty.…”

This report describes the activities discussed at the 10th meeting of Section II of the Consultative Committee on Standards for the Measurement of Ionizing Radiations (Comité Consultatif pour les Etalons de Mesure des Rayonnements Ionisants, CCEMRI) held in May 1989 at Sèvres (France). Topics included present and future international comparisons of activity measurements, the status and possible extension of the International reference system for activity measurements of gamma-ray emitting nuclides, reports from other working groups, accomplishments at the International Bureau of Weights and Measures (Bureau International des Poids et Mesures, BIPM), and progress at member laboratories.
