- Abstract:
- Assessment of risks connected with exposure to electromagnetic fields at either low or radio frequencies requires appropriate evaluation of the value read on probe’s display – whose variability depends on both EM field and measurement system – with respect to the actual value of the underlying monitored process. That can be accomplished through a statistical investigation about whether the overcome of reference limits which can possibly have happened is merely a transient effect of measurement uncertainty which sums up with random process variation, or rather a more serious stable condition which calls for countermeasures.
To that end, it is required that the probability distribution of the monitored process be obtained from the set of measured data, which can be done by taking out of them the fluctuation due to measurement itself. Such methodology falls under the generic name of deconvolution, after the operation used to separate the two contributions, and requires a preliminary measurement campaign for the evaluation of the statistical distribution of data. This paper presents the mentioned methodology and provides an example pertaining the evaluation of the electromagnetic field in urban area. - Keywords:
