MEASUREMENT AND EVALUATION OF RF FIELDS Sample Clauses

MEASUREMENT AND EVALUATION OF RF FIELDS. Trained personnel should use measurement procedures and techniques such as those recommended in IEEE C95.3-1991, as basic guidance. This requirement does not preclude using other RF measuring and evaluation methodologies. a. Records of surveys, reports, calculations, and control measures imposed should be maintained for each fielded RF emitter which is capable of exceeding the PELs in Table C-I. b. Where multiple RF emitters may be collocated in fixed arrangements, such as aboard ships or at communication sites, RF field evaluation data should include a determination of the weighted contribution from emitters expected to be simultaneously operated to ensure that personnel are not exposed to RF levels above the applicable PEL. To comply with the PEL, the fraction of the PEL in terms of E2, H2 (or power density) incurred within each frequency interval should be determined and the sum of all the fractions should not exceed unity. Probes containing dipole-diode elements separately or in conjunction with thermocouple elements have been designed to provide a readout in “% of the Standard.” The proves are tailored to the specific PEL or Maximum Exposure Permitted (MEP) specified in the IEEE Std C95.1-1999. ANNEX E TO STANAG 2345 (Edition 3) ACTIONS TO BE TAKEN IN CASE OF 1. All national forces of NATO members shall investigate and document all incidents involving exposures that may exceed the PELs described herein. 2. Because of the safety margin incorporated into the PEL, exposures in excess of the PEL are not necessarily harmful. As a minimum measure, the following actions for personnel exposures occurring at, or above, five times the PELs in terms of the spatial and time averaged power density, in Table C-I, will be taken: a. RF field measurements for documentation of the RF exposure that may have been received. b. Review of the circumstances and counseling by a Medical Officer, with notation in the medical record which is to include the decision whether ophthalmologic referral is recommended. c. Documentation should provide a complete description of the circumstances surrounding the exposure incident, equipment operating parameters at the time of the incident, statements from personnel involved in that incident, and recommendations to prevent similar occurrences. A RFR Overexposure Medical Format Proforma may be used to document physical considerations and circumstances (Xxxxx X). d. The national forces of alliance members should maintain a repository file fo...
