EMF Survey Services

House SurveyAn EMF Survey is a thorough inspection of your home – or a house or flat you wish to buy or rent – for  low-frequency and radio-frequency radiation.

The surveyor takes EMF measurements in each room in the house, especially where people spend most of their time – bedrooms, sitting rooms, kitchens, dining rooms, and children’s play areas.

EMF hotspots indoors are often very localized, so they can affect one part of a house much more than another. Sometimes locations a foot or two apart can experience very different EMF levels.

Why Order an EMF Survey?

High EMF levels are associated with many undesirable health effects and more people are becoming aware of them.

The main advantage of an EMF survey is that it gives you dependable information you can take action on. It is your first step towards reducing biological stress on your family from harmful radiation.

Ideally, your home should be a low-EMF zone, a refuge from the high EMF levels found everywhere today, in public and private places.

But this is not always easy. You first need to know exactly where EMF levels are too high – and why – so that you can reduce the radiation (if this is possible) or take other steps to limit your exposure.


When to order an EMF Survey

One really good time to order an EMF survey is when you are thinking of buying a house, before you are committed to the contract.

There are also very strong reasons for ordering an EMF survey for a property you wish to sell, because it reduces buyer uncertainty and increases confidence.

But if you have not yet had your property tested for radiation, maybe now is the right moment?

It is important to spend most of your time in a place where EMF levels are low, because health effects from EMF exposure are cumulative.

Unfortunately, many people don’t think about EMF levels in their home until someone in the household experiences an unexplained decline in health.

Who should perform your electromagnetic radiation survey?

You could do it yourself if you have suitable meters and are technically inclined, but a professional EMF surveyor may be better able to identify radiation sources and suggest how to deal with them.

There is no professional qualification or body which regulates electromagnetic radiation inspectors, so you will want to be confident that the person you choose is up to the job. Experience is the best teacher – so if you can, find someone who has done more than a few.

So how would we handle your EMF survey?

The EM Watch approach to EMF Surveys

EMF VulnerableIf our client is the property owner or occupier, we will take measurements with radio-frequency transmitting devices switched on, and then switched off, to get a full picture of internal and external radiation sources.

If we are surveying a property on behalf of a buyer, we will request that all radio-frequency transmitting devices (such as mobile phones, wi-fi or cordless phones) be switched off, to allow us to concentrate on external sources.

The assessment will include these steps

  • Check each room in the house for radio-frequency radiation
  • For any hotspot found, consider EMF protection options, including radiation shielding
  • Check each room for low-frequency radiation.
  • Determine the source and extent of any EMF detected
  • Check certain appliances for radiation
  • Note any low-frequency EMF caused by wiring issues
  • Check for EMFs from lighting and heating circuits, if appropriate
  • Check for smart meter transmissions – if a smart meter is installed
  • Check the garden for low-frequency and radio-frequency radiation.

An EMF survey can take up to two hours on site for a medium-sized (3-4 bed) house.

EMF Survey Report

Most of our clients require a written EMF Survey report. Often this is because they want to use the report and its conclusions to help them with an important decision, for example a property purchase.

Our report will show all recorded radiation measurements, and indicate a level of concern for each one.  These measurements serve as a useful record of the survey findings, and make future comparisons possible.

We also comment on any EMF levels which are unusually high or low. And where EMF levels could represent a health hazard, we are often able to recommend action to reduce exposure.

We email the survey report to our client, usually on the day after inspection.

We also answer any questions arising out of the survey or the report, until the client is satisfied.

Common EMF Survey Findings

Bedroom EMFMore often than not, when we perform an EMF home survey, we find elevated radiation levels in some parts of the home.

Sometimes these hotspots can be eliminated by switching off appliances or electronic devices – at least at night when they are not in use.

Where radio-frequency radiation enters from outside (for example from a mobile phone mast) it may be possible to screen certain windows with special net curtain material, or window film, to reduce the penetration.

Radio-frequency sources inside the house can often be re-positioned or partially screened to reduce radiation to more acceptable levels.

Low-frequency radiation can’t be screened, but it is still helpful to know about it, and how far it extends from the source – so that exposure can be minimised.
