Development of magnetic near-field probes.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. 75-127, 1975 Jan; :1-28
The development of two portable magnetic-field strength probes by the National Bureau of Standards (NBS) for NIOSH is described with details of the design, construction, calibration and proper usage of the probes. Topics also include errors due to temperature variations and harmonics, electric-dipole response of a loop antenna, partial-resonance effect in a loop antenna, and the NBS conducting-plastic transmission line. The probes can be used to accurately measure magnetic near fields which exist within a few centimeters of a radiofrequency radiation source.
