Non-Ionizing and Ionizing Radiation
Radiation exists across a spectrum from very high-energy (also referred to as high-frequency) radiation to very low-energy (or low-frequency) radiation. This is sometimes referred to as the electromagnetic spectrum.
Examples of high-energy radiation include x-rays and gamma rays. They, as well as some higher energy ultraviolet (UV) rays, are classified as ionizing radiation, which means that they have enough energy to remove an electron from (ionize) an atom. Ionizing radiation can damage the DNA inside cells, which can lead to mutations and the uncontrolled cell growth we know as cancer.
Non-ionizing radiation has enough energy to move atoms around or make them vibrate, but not enough energy to remove electrons. Extremely low frequency (ELF) radiation is at the low-energy end of the electromagnetic spectrum and is a type of non-ionizing radiation associated with electricity.
With most types of radiation, the electric and magnetic fields are coupled. Because they act as one, they are considered together as an electromagnetic field (EMF). With ELF radiation, the magnetic field and the electrical field can exist and act independently, so they are often studied and measured separately. Typically, we use the term “magnetic field” to indicate ELF radiation from a magnetic field, while we use “electric field” to mean ELF radiation from an electric field. ELF radiation has even lower energy than other types of non-ionizing radiation like Radio Frequency, Visible Light, and Infrared. Radio Frequency is a higher frequency associated typically with wireless communication. Although non-ionizing radiation is less energetic than ionizing radiation there are many people who believe it can affect body processes on the cellular level.

Less EMF specializes in meters that measure and products that shield/reduce Non-Ionizing Radiation from ELF through Radio Frequency and Microwaves. Non-Ionizing radiation can be measured by meters that measure a specific type of radiation or by combination meters that measure multiple types of radiation. Each type of radiation is shielded or reduced with different products and methods. Low frequency magnetic fields are measured in Gauss or milliGauss (G, mG) and are reduced using specially manufactured solid metals such as Magnetic Shielding Foil and Giron. Low frequency electric fields are measured in Volts per meter (V/m) and are mitigated by grounding. Radio Frequency/Microwave radiation is measured typically in either milliWatts per meter squared (mW/m2) or Volts per meter (V/m) and are shielded using fabrics and paints, such as Nickel Copper Ripstop and Cu-Pro Cote.
Less EMF also carries meters and products for Dirty Electricity, Body Voltage, Ionizing Radiation, Socket Testing, along with many other unique items.
