What are Electromagnetic Fields (EMFs)?
Electromagnetic fields are areas of energy that surround electronic devices and are created by the interaction of electric and magnetic forces. EMFs are categorized into two main types: ionizing and non-ionizing radiation. Ionizing radiation, such as X-rays and gamma rays, has enough energy to break chemical bonds and cause damage to living tissues. Non-ionizing radiation, on the other hand, has lower energy levels and is typically emitted by devices such as radios, microwaves, and cell phones.
Types of Non-Ionizing EMFs
There are several types of non-ionizing EMFs, including:
Radiofrequency radiation (RF), which is emitted by devices such as cell phones, radios, and televisions. RF radiation has a relatively high frequency and is used for wireless communication.
Extreme low frequency (ELF) radiation, which is emitted by devices such as power lines, electrical wiring, and household appliances. ELF radiation has a very low frequency and is often associated with electrical currents.
EMF Frequency and Intensity
The frequency and intensity of EMFs play a crucial role in determining their potential impact on the human body. The frequency of an EMF is measured in hertz (Hz), while its intensity is measured in units of power density, such as watts per square meter (W/m²) or milligauss (mG). Higher frequency EMFs tend to have more energy and are more likely to cause biological effects, while higher intensity EMFs can increase the risk of adverse health effects.
