Electric, magnetic and electromagnetic fields (EMF) are widely used in medical . exposure to high frequency electromagnetic fields and its effect on human immune parameters.
Electric, magnetic and electromagnetic fields (EMF) are widely used in medical diagnostic and. therapeutic applications. EMF of sufficient strength can have biological effects and some medical. Another possibility is the application of metallic shielding to the. side of the coil facing the operator (and away from the patient). For diathermy, possible technical.

The National Radiological Protection Board (NRPB) was a public authority in the UK created by the Radiological Protection Act 1970. It was also authorized to provide technical services and charge for them. Originally NRPB dealt only with ionizing radiation, but its functions were extended in 1974 to non-ionizing radiation.
Reproduced with permission from NRPB) . Exposure to magnetic fields arises from power lines and the use of electrical appliances. Ambient fields from the supply to the house are always present and expose the whole body, whereas those from appliances are intermittent and expose part of the body. I thank the National Radiological Protection Board, the International Commission on Non- Ionizing Radiation Protection, Professor John Moulder and Dr Colin Martin for their permission to reproduce some of the figures.

The ICNIRP guidance was adopted by the UK National Radiological Protection Board (NRPB) in 2004, also including a 2 T limit for static field exposure. We anticipate that UK regulators may attempt to include this static field in domestic law, even in the absence of a Europe-wide limit. Occupational exposure limits are likely to be an important component of safe operation, but the limits proposed in the EU Directive, especially for gradient frequencies, seem to be based on inadequate science. Their implementation will lead to curbs on the use of MRI in healthcare without any clear benefit to staff.
