What’s the relationship between EMI and the human health effects of electromagnetic fields?
In apparatus suffering EMI, the levels at which it may be affected are often relatively low ( for commercial products, anyway) and its response is immediate. For humans, the known dangerous field strengths are a lot higher, and they need to be applied for a long time to have a measurable effect. The National Radiological Protection Board (www.nrpb.org) are responsible for advising on the health effects of electromagnetic fields.
