Abstract

Effective Analysis of Human Exposure Conditions with Body-worn Dosimeters in the 2.4 GHz Band de Miguel-Bilbao S, Blas J, Ramos V. Effective Analysis of Human Exposure Conditions with Body-worn Dosimeters in the 2.4 GHz Band. J Vis Exp. 2018 May 2;(135). doi: 10.3791/56525. Abstract A well-defined experimental procedure is put forward to evaluate maximum exposure conditions in a worst-case scenario whilst avoiding the uncertainties caused by the use of personal exposimeters (PEMs) as measuring devices: the body shadow effect (BSE), the limited sensitivity range, and the non-identification of the radiation source. An upper bound for exposure levels to EMF in several indoor enclosures has been measured and simulated. The frequency used for the study is 2.4 GHz, as it is the most commonly used band in indoor communications. Although recorded values are well below the International Commission for Non-Ionizing Radiation Protection (ICNIRP) reference levels, there is a particular need to provide reliable exposure levels within particularly sensitive environments. In terms of electromagnetic field (EMF) exposure, limits established in national and international standards for health protection have been set for unperturbed exposure conditions; that is, for real and objective exposure data that have not been altered in any way. ncbi.nlm.nih.gov

Main findings

The authors propose an experimental procedure to evaluate maximum (worst-case) exposure conditions while avoiding uncertainties associated with personal exposimeters. Upper-bound exposure levels in several indoor enclosures were measured and simulated at 2.4 GHz, and recorded values were reported as well below ICNIRP reference levels.

Outcomes measured

  • Measured and simulated upper bound exposure levels to EMF in indoor enclosures
  • Comparison of recorded values to ICNIRP reference levels
  • Assessment of uncertainties in personal exposimeter measurements (body shadow effect, sensitivity limits, source identification)
