The current state of development of the metrological provision of measuring equipment for the competitiveness of products, safety at work (radiation safety), obtaining objective diagnostic information in medical practice is analyzed. Metrological support is one of the main steps in the production process that influences the measurement results and their qualitative evaluation.
Prospects of development and improvement of metrological support of measurements in the industry are considered. Improvement of metrological assurance of measurements in industry (especially in nuclear power) should go in the direction of development of methods of dismantling control of metrological serviceability of measuring instruments, including test equipment as well as the theory and practice of individual evaluation of metrological reliability of measuring instruments.
Proposed ways to ensure the accuracy of measurement results in improving the metrological support of industrial measuring instruments are introduction and development of:
– methods of unmanaged metrological verification and creation of program-controlled and highly reproducible calibrators
– evaluation of reliable indicators of measuring instruments into metrological practice;
– methods of objective estimation of the metrological reliability index of specific measuring instruments.
The necessity of development of estimation methods of sources of ionizing radiation, determination of their place in the control of technological parameters is emphasized. This allows for enhancing the level of metrological support in nuclear area and medicine. In order to ensure the proper quality of the diagnostic information or therapeutic effect, it is necessary to carry out regular inspections of technical condition of sources of ionizing radiation, conducting their tests, and to check for leaks.
