Ecological Systems and Devices Annotation << Back METROLOGICAL ASSURANCE FOR MEASURING ELECTROMAGNETIC FIELD LEVELS G.N. Akhobadze The paper introduces a metrological assurance principle for measuring electromagnetic field levels in a microwave wave band. Analysis and comparison of specifi ed parameters in accordance with sanitary regulations and standards for laboratory researches on electromagnetic radiation protection methods are given. Experimental results of measurements of power fl ow density are shown depending on a radiator-receiver distance and radiation directivity. Comparative appraisal of results of measurements of power flow density and maximum permissible electromagnetic field levels in a microwave wave band is provided. Accuracy and sensitivity of power fl ow density measurements are estimated in terms of metrology. A principle for determination of measurement end results which provides data validity is discussed. Field of application of the results is demonstrated. Keywords: accuracy; level; power; measurement; frequency; accuracy; detection section; radiation; fi eld.
