VK3UM Electro Magnetic Radiation Calculator (EMRCalc)
(also now known as Electro Magnetic Emission, and/or Electro Magnetic
Field (EMF) calculation.. a more public friendly name !)
Throughout the World, most Government Authorities have implemented
mandatory standards of radiation limits pertaining to Electro Magnetic
Radiation. These requirements include the Amateur Radio Service.
Because of the nature of EME (Earth-Moon-Earth) and many other Amateur
communications, radiated power levels can be quite high and may, under
certain situations, pose a radiation hazard.
This software calculates the level of Far Field bore site RF Radiation
levels and indicates if the safety limit will be exceeded with respect
to the parameters entered into the program.
The default calculations are for Public or un-controlled environments,
however controlled environment calculations are provided where
situations permit such limits. Warnings are provided on entering this
The software also addresses the near field radiation characteristics of
a circular aperture radiating antennae. This characteristic could be of
considerable significance to provide substantiating evidence that the
installation is able to meet the Governing Authority's radiation limits.
The most widely accepted Safe level of RF Radiation is that which has
been recommended by the International Commission on Non-Ionising
Radiation Protection. (ICNIRP) It is a body of independent scientific
experts consisting of a main Commission of 14 members, 4 Scientific
Standing Committees covering Epidemiology, Biology, Dosimetry and
Optical Radiation and a number of consulting experts.
This expertise is brought to bear on addressing the important issues of
possible adverse effects on human health from exposure to non-ionising
radiation. Its recommendations have been accepted by most countries as
well as the Council of European Union (CEU).
