Useful Tips You Should Know About Electromagnetic Compatibility
Electromagnetic fields are all around us. They're generated by electrical devices like light bulbs, hairdryers, and microwaves, but also come from natural sources like the earth's magnetic field. But how much do we really know about these invisible waves? What dangers do they pose to our health? And can we protect ourselves against them? We'll explore these questions in this article.
1 - How do EMFs affect our bodies?
Electromagnetic fields, or EMFs, are invisible waves that surround all electrical devices. We can't see them but we're exposed to their effects every day-EMFs can penetrate almost any object and many of us spend hours each day near various sources of electromagnetic radiation. But do we know how they affect our bodies? And does it matter whether the electricity that powers an appliance comes from a wall outlet or its own battery? You can answer these questions and more by using EMC Testing Equipment to identify the levels being emitted around you. EMC is important as it can affect your health.
2 - What exactly is an electromagnetic field?
Electromagnetic fields are a type of radiation, meaning they can travel through empty space as well as solid objects. They aren't beams or rays like light and X-rays but instead have both a strength and a direction. EMFs surround electrical devices so they're often measured in volts per meter. IfWhat are the dangers of EMFs?
Although many people don't understand exactly what EMFs do, there is mounting evidence that living in close proximity to electrical devices poses some risks. According to many scientists, the waves have been linked to a variety of ailments including headaches, insomnia and cancer. But others argue that electromagnetic fields are harmless and that there's not enough evidence to prove otherwise. In fact, in 2011, an international team of researchers conducted a study involving more than 100 scientists from 10 different countries who examined all of the research so far and concluded that there was no strong evidence to support any harmful effects on humans.
3 - What can we do to limit EMFs in our homes?
Since the harmful effects of electromagnetic fields aren't proven, many scientists say that it's impossible to know just how much exposure is too much. So what's the best way to protect ourselves? Some experts recommend unplugging appliances, or at least letting them cool down before putting them back into use. Leaving your cell phone plugged into its charger, for example, could potentially expose you to radiation-even if it is fully charged. One easy solution? Make sure your mobile device is turned off whenever possible.
4 - How can we protect ourselves against EMFs?
Electrical appliances and other electronics emit electromagnetic fields, but we're exposed to these waves on a daily basis-not just from home devices but also cell phones and other wireless technologies. While experts argue over the risks that such exposure might pose to our health, and how best to reduce them, there's one sure way to avoid the effects of EMFs: don't use electronic devices. Vacuum cleaners, stoves and other appliances emit EMFs too, so it's important to unplug when they're not in use. If these changes seem drastic, there are a few simple things we can do:
- Turn off your mobile device or switch it to airplane mode when there's no reception.
- Keep your cell phone away from your body as much as possible, and consider using a headset, speakerphone or air tube hands-free device.
- Get rid of old cordless phones - they emit both EMFs and microwaves.
5 - Effect on product performance
Electromagnetic Compatibility (EMC) is an important consideration in the design of modern products. EMC ensures that a product performs as expected when used in its intended environment and that it is compatible with other devices in use around it. To define this performance, electrical engineers need to understand how a device will be used and what interactions might occur between the device and other EMC-sensitive systems.
The need for EMC control will vary from product to product, but it is often a requirement in the design of safety-related products such as household appliances, medical devices, vehicles and industrial machinery. Designers therefore need to understand how an EMC test system can meet their requirements and what capabilities are needed to ensure that their device satisfies the expected EMC performance.
6 - How to tell if your home has a high EMF reading?
Many appliances emit electromagnetic fields, but some of the most common sources include computers, electrical wiring and fluorescent lights. In fact, if you use a device that plugs into an electrical socket or runs on batteries from time to time, then it probably emits an EMF of some kind. One way to measure the waves in your home is to track their readings with an EMF meter. But if you don't want to buy such a device, you can simply pay attention instead: anything that makes noise or emits light has some EMF emissions too.
7 - Effect on our long-term health
The danger of electromagnetic fields is still an unanswered question, but scientists who study this area believe that it's best not to assume that these fields are harmless. While the National Institute for Standards and Technology in the US has put out a statement saying there's no "conclusive proof" of harm from EMFs, it has suggested that adults (and particularly pregnant women and children) take some simple steps to avoid exposure when possible.
Electromagnetic compatibility is important for the design of modern products. We can't be sure if EMFs are harmful to our health, but it's best not to assume that they're harmless. With this in mind, here are some safety-related tips you should follow: unplug appliances when they're not in use; turn off your mobile device or switch it to airplane mode when there's no reception; keep your cell phone away from your body as much as possible and consider using a headset/speakerphone or air tube hands-free device, get rid of cordless phones - they emit both microwaves and electromagnetic fields. If these changes seem drastic, there are simple things we can do instead: make sure our devices aren't plugged into outlets where they could emit EMFs when not in use, and turn off the bedroom light - its electric wiring emits a lot of lights.
