Título A Practical Guide to the Determination of Human Exposure to Radiofrequency Fields
Resumo NCRP Report No. 119 is intended to constitute a compendium of general knowledge useful to those health and safety professionals concerned with evaluating radiofrequency hazards. It provides a comprehensive collection of information on various radiofrequency radiation sources and a straightforward “how to” guide for estimating the exposures associated with these sources. Major sections of the Report treat the following subjects: • basic concepts, including definitions of terms and units • procedures for evaluation of exposures • instruments and measurement techniques • recommended areas for further research and technical or engineering development Appendices provide a quick reference source for use in assessing the relative significance of exposures from various radiofrequency sources, including a description of methods for performing practical measurements and computations. Explicit examples of exposure surveys for selected common sources are provided.

Título Guide to the Expression of Uncertainty in Measurements
Resumo When reporting the result of a measurement of a physical quantity, some quantitative indication of the result has to be given to assess its reliability and to allow comparisons to be made. The Guide to the expression of uncertainty in measurement establishes general rules for evaluating and expressing uncertainty in measurement that can be followed at many levels of accuracy and in many fields.

Título IEEE Recommended Practice for Measurements and Computations of Radio Frequency Electromagnetic Fields With Respect to Human Exposure to Such Fields, 100 kHz–300 GHz
Resumo Techniques and instrumentation for the measurement and computation of potentially hazardous electromagnetic (EM) fields both in the near field and the far field of the electromagnetic source are specified. The specifications previously set forth in IEEE Std C95.3-1991 are extended and combined. Leakage and near-field measurements and a description of the concepts, techniques, and instruments that can be applied to the measurement of specific absorption rate(SAR) or the electric field strength in organisms (including humans) and phantoms exposed to electromagnetic fields are included. Below 100 MHz, the current flowing through the body to ground is measurable and can be used to determine the SAR and, therefore, a brief treatment of lowfrequency body current measurement is included.
