What type of radiation are VHF and UHF radio signals?

VHF (Very High Frequency) and UHF (Ultra High Frequency) radio signals are classified as non-ionizing radiation. This classification is significant because non-ionizing radiation does not carry enough energy to ionize atoms or molecules, meaning it cannot remove tightly bound electrons from their orbits around atoms. This type of radiation includes radio waves, microwaves, and infrared waves, which are all common in communication technologies, including amateur radio.

Understanding the nature of these radio signals is essential for safe operation and compliance with regulations. Unlike ionizing radiation, which includes types like gamma rays and X-rays that can cause damage to biological tissues and DNA, non-ionizing radiation is generally considered safe at the exposure levels typical of radio operations. This distinction highlights the importance of recognizing the various radiation types and their implications for health and safety in radio communications.
