This non-ionizing radiation field can be generated by a variety of sources, including power lines, electrical wiring, and personal appliances like electric shavers, hair dryers, and electric blankets. Extremely low-frequency EMFs (ELF-EMFs).Human-made EMFs are classified into two types, both generated by non-ionizing radiation: The earth’s magnetic field is an example of a natural EMF. Non-ionizing EMFs come from both natural and human-made sources. This category of EMFs includes extremely low frequency EMFs (ELF-EMFs) and radiofrequency EMFs (RF-EMFs). Household appliances like microwave ovens, cellphones, hair dryers, and washing machines, as well as power lines and MRIs, produce this type of radiation. It’s mild and thought to be harmless to people. This is the non-ionizing type of radiation. Other sources include gamma radiation from radioactive elements and UV radiation from either tanning beds or the sun. Medical devices like X-ray imaging machines and CT scans produce low levels of this type of radiation. Scientific literature agrees that large exposures can damage DNA or cells. In summary, here are the two types of EMFs that you might be exposed to: So we use the terms “magnetic field” and “electric field” to refer to these two different fields in ELF radiation. The result is called an electromagnetic field (EMF).īut the electric and magnetic fields in ELF radiation can act independently. In between ELF radiation and high-energy radiation on the spectrum are other types of non-ionizing radiation, like:Įlectric and magnetic fields join as one field in most forms of radiation. It can move atoms around in the body or make them vibrate, but most researchers agree that it isn’t enough to damage DNA or cells. This is a type of non-ionizing radiation. On the other end of the spectrum is extremely low-frequency (ELF) radiation. Ionizing radiation can damage the body’s DNA and cells, which may contribute to genetic mutations and cancer. This is ionizing radiation, meaning this energy can affect cells on the atomic level by removing an electron from an atom, or “ionizing” it. some higher-energy ultraviolet (UV) rays.This radiation ranges from very high-energy (called high-frequency) on one end of the spectrum, to very low-energy (or low-frequency) on the other end.Įxamples of high-energy radiation include: Radiation exists across what’s called the electromagnetic spectrum.
