Abstract: | This article presents methods and results of interlaboratory comparison in the electromagnetic field (EMF) survey measurements
performed by Electromagnetic Environment Protection Laboratory. Based on the results, the author analyzed factors affecting
the precision of EMF measurements, in particular—difficult to estimate—the “human factor”. In practice, the human factor has
never been taken into account in the EMF measurements accuracy estimations budget, and the author estimate the importance
of this factor that may include even up to half of the total uncertainty of measurements. Taking into account all factors
depredating the accuracy of measurements, the uncertainty of the survey EMF measurements was estimated at the level of 2–4 dB. |
