Article 14 - REGISTRATION OF NONIONIZING RADIATION SOURCES AND STANDARDS FOR PROTECTION AGAINST NONIONIZING RADIATION
Section R9-7-1410 - Radio Frequency Compliance Measurements
Current through Register Vol. 30, No. 38, September 20, 2024
A. For obtaining measurements to determine compliance with R9-7-1405, the Department shall use an instrument capable of measuring the field strength and frequency of radiation.
B. The Department shall ensure that each instrument used for compliance measurements is calibrated every 12 months. The calibration shall be performed in a manner that meets the standards in IEEE Std C95.1-1999, incorporated by reference in R9-7-1404(A).
C. For compliance measurements of exposure conditions in the near field, the Department shall obtain measurements of both the electric and magnetic field components. The applicable protection standards for near field measurements are the mean squared electric and magnetic field strengths (using the applicable MPE) referenced in R9-7-1405.
D. If the Department is obtaining measurements to determine compliance in far field exposure conditions, the Department may use measurements of power density in milliwatts per square centimeter or the calculated equivalent plane wave power density, based on measurement of either the electric or magnetic field strength. The applicable protection standards are the power density values (using the applicable MPE) referenced in R9-7-1405.
E. In obtaining measurements in accordance with this Section, the Department shall measure the electric and magnetic field strength:
F. For mixed or broadband fields at frequencies for which there are different protection standards, the Department shall determine the fraction of the applicable MPE incurred within each frequency interval. To achieve compliance the sum of all the fractions shall not exceed unity (1).
G. The Department shall obtain compliance measurements at a distance of five centimeters or greater from any object.
H. A registrant shall obtain measurements that are averaged over a six-minute period for pulsed and non-pulsed modes of radio frequency emission and make a correction for duty cycle in determining the average field strength.
