National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of Magnetic Near-Field Probes.

PB266298

Publication Date	1975
Personal Author	Greene, F. M.
Page Count	40
Abstract	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. The probes were developed for use in assessing the occupational exposure from magnetic-fields.
