FCC Technician Exam Question Of The Day (T0C01)
Q) What type of radiation are VHF and UHF radio signals?
A) Non-ionizing radiation
NJ2X Notes:
Non-ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules. Non-ionizing radiation with sufficient power can cause heating in living tissue. VHF and UHF radio signals are non-ionizing radiation.
Ionization removes an electron from an atom or molecule. Ionizing radiation is dangerous since it damages DNA. Examples of ionizing radiation include X-rays and gamma rays.
