Low Frequency EMF Survey

The EMF levels are changing every second, so to provide the most accurate readings we take several readings in each room, as well as any outdoor areas that belong to the property, over a certain period of time.

In the report, you will see all readings taken in each room, as well as the average value and how the highest recorded reading compares to the international guidelines. We will also advise how the results compare to the SAGE biological guidelines (this provides much stricter reference levels than ICNIRP, adopted by the UK government).

Low frequency (LF) electric and magnetic fields (EMF) occupy the lower part of the electromagnetic spectrum in the frequency range 1Hz-100KHz. LF EMFs result from electrically charged particles. Artificial sources are the dominant sources of LF EMF and are usually associated with the generation, distribution, and use of electricity at the frequency of 50 Hz or 60Hz. The most common examples are substations, power pylons, electrical wiring, and home appliances. The electric field is produced by the voltage whereas the magnetic field is produced by the current and is commonly expressed in μT (microtesla) or nT (nanotesla).

EMF produced by high voltage power lines, carried by power pylons, is a very strong source of EMF. Especially residential properties located within 100m from power lines or power pylons are at risk of being exposed to potentially harmful levels of EMF. Conducting an EMF test will allow you to make a well informed decision before buying a new property or evaluate your existing home for any potential risks related to EMF. Low frequency EMF doesn't travel or expand, it rather exists within a specific perimeter from the source. However, low frequency EMF is near impossible to effectively shield in regular conditions, this makes conducting an EMF survey, prior to buying a new property, extremely valuable.
