AR RF/Microwave Instrumentation earlier this year announced a line of meters, sensor heads, and analyzers that provide a simple solution to EMF measurement and can help comply with various regulations. The company has also published an application note explaining that “The demand for these products is rapidly increasing with companies and the public becoming more aware that human exposure to electromagnetic fields (non-ionizing radiation) should be measured and controlled.”
The note continues, “This heightened awareness is beginning to result in new guidelines regarding maximum permitted exposure levels for both the general population and workers within specific industries. For instance, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has released many publications in recent years describing the possible threat and identifying suggested safe-levels for exposure to RF radiation. The International Agency for Research on Cancer (IARC), a component of the World Health Organization, has taken a similar approach as well.”
The note further states, “In addition to the standards and recommendations listed above, the U.S. government has recognized the harmful effects of non-ionizing radiation and has adopted the limits from the IEEE C95.1 standard….”
The application note includes tables indicating MPE (maximum permissible exposure) for limbs, whole-body MPE, and other specifications.
It outlines the applicability of its testers and meters to industrial ovens, welding equipment, diathermy equipment, medical devices, RF generating equipment, electric generating plants, sensitive sites related to nuclear magnetic resonance (NMR) imaging, railways and ground transportation systems, wireless telecom systems, and more.
