Description
The National Metrology Institute of South Africa (NMISA) Radioactivity Standards laboratory maintains the standard for radioactivity in South Africa. The nuclear industry requires dissemination of high accuracy, low uncertainty calibration standards. Where the quality of life of the public is of concern, the accuracy of various instruments used to measure radioactivity is extremely important. Through primary measurements, high accuracy, low uncertainty calibration standards are produced, which can be used to calibrate HPGe detectors for environmental measurements of radioactivity. The NMISA secondary standard ionisation chamber is also calibrated to measure nuclear medicine and calibration factors can be determined for hospital and isotope production facilities ionisation chambers. Through participation in international comparisons of radioactivity measurements using primary measurement methods, we ensure the quality of our results and demonstrate equivalence with international metrology institutes. Our primary measurement methods are described and successful participation in more than 40 international comparisons is discussed.
