EMF testing is used to assess the electromagnetic field in a building or device. Using a Geiger counter or an EMF meter, an EMF tester measures the level of electromagnetic fields in the environment. High levels of electromagnetic fields can harm humans and interfere with analytical equipment. Typical sources of high levels of electromagnetic fields include appliances, power lines, flaws in building wiring, and stray currents in utility pipes. This information can help determine the safety of your living space.
EMF meters measure electric and magnetic field strength, magnetic flux density, and contact current. When these measurements exceed reference levels, further analysis is needed. These meters usually max out at around 20 mW/cm2 and 6 V/m, respectively. You should be cautious about touching the meter or source during EMF testing.
EMF site surveys can also be used for regulatory purposes, ensuring that an organization complies with the EMF Directive 2013/35/EU. These surveys are part of a company’s Health and Safety at Work (HSW) policy. Organizations must keep documentation of the results of EMF site surveys. In addition, an EMF site survey will include a verbal debrief of the results and an extensive report detailing the study results.
If you don’t have the time to perform a comprehensive assessment on your own, it may be in your best interest to consult with a certified electromagnetic radiation safety consultant. These professionals can help you mitigate exposures and provide guidelines to minimize risk. The costs of such tests are usually $300-500. EMRSs are specialized in the field and adhere to the highest safety standards. A professional EMF testing company will perform a thorough assessment and report with detailed instructions on how to mitigate exposures.
While EMF meters provide a number of measurements and reports, they do not tell the true magnitude of the EMF. The EMF level displayed on the screen is just a proxy for the field strength. It should be compared with the actual level to be sure you are safe. The basic reading is more important than the display. A good EMF meter should provide an EMF level within your comfort zone.
In some areas, electromagnetic fields may be hazardous, especially in places of high voltage. For these reasons, the government has mandated the testing of wireless devices. This is known as SAR testing, and the testing must be conducted before a device can be sold. The government has also established rules to protect the public from high levels of EMF. These regulations require manufacturers to ensure that their products are safe and do not interfere with other wireless devices.
The electromagnetic field has two main characteristics: frequency and wavelength. Each of these characteristics affects the human body in different ways. The frequency of an electromagnetic wave refers to how many oscillations occur in a second, while the wavelength relates to how far the waves travel in a specific direction. Higher frequency EMFs are more harmful than low-frequency ones, as they can affect human health.
There are two types of EMFs: low-to-mid-frequency EMFs and high-frequency EMFs. The former includes radiofrequency electromagnetic fields, which are those that come from cell phones and wireless routers. The frequency of radiofrequency EMFs ranges from three kilohertz to 300 gigahertz.
Higher-frequency EMFs include x-rays and gamma rays. These are in the ionizing radiation part of the electromagnetic spectrum and can damage cells and DNA. If your device is exposed to high levels of EMF, you need to ensure it is shielded.
