| Abstract: | The article gives a review of the present state of the problem of standardization of radioactive sources and of the methods for measuring radioactive radiations. The general principles for organizing systems of radiometric measurements based on the use of a single unit system, of standard methods and equipment, and of relative measurements involving standard sources are illustrated. A scheme is reported for the verification of radioactive sources graduated in activity units: a standard method for reproducing the Curie unit is taken as the basis of this scheme. The fundamental characteristics of standard and check radioactive sources are briefly described. |
