Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF) and extremely low frequency (ELF). Lasers commonly operate in the ...

Cell phones emit non-ionizing radiation, which does not increase cancer risk. Research found no rise in brain tumors linked to cell phone use. Long-term health effects are still being observed; ...

Radiation can be defined as energy traveling through space. There are two types of radiation, ionizing and non-ionizing, which are differentiated by how they interact with matter. Non-ionizing ...

Electricity is a regular part of life these days. Most people who grew up in the U.S. don’t know what it’s like to live without a readily available energy source in their home. Our homes are filled ...
