Question
How does RF radiation differ from ionizing radiation (radioactivity)?
Answer Options
- A) RF radiation does not have sufficient energy to cause chemical changes in cells and damage DNA
- B) RF radiation can only be detected with an RF dosimeter
- C) RF radiation is limited in range to a few feet
- D) RF radiation is perfectly safe
Correct Answer: A
Explanation
The fundamental difference between RF radiation and ionizing radiation (like X-rays or Gamma rays) is the energy level of the photons they carry. Ionizing radiation has enough energy to knock electrons out of atoms, which is called ionization. This process breaks chemical bonds, causing serious damage to living cells and DNA.
RF radiation is classified as non-ionizing, meaning it does not have sufficient energy to cause chemical changes in cells and damage DNA. Its principal biological effect is heating tissue, which is why safety standards focus on limiting exposure to prevent excessive heating.
