Gamma rays are absorbed by dense materials such as lead and concrete. These materials act as effective shields due to their high atomic number and density, which help in attenuating the high-energy photons.

FAQs & Answers

  1. What materials are used to shield against gamma rays? Dense materials like lead and concrete are commonly used for shielding against gamma rays due to their high density and atomic number.
  2. How do gamma rays interact with matter? Gamma rays interact with matter primarily through photoelectric absorption, Compton scattering, and pair production, with dense materials being most effective in absorption.
  3. What is the difference between gamma rays and X-rays? Both gamma rays and X-rays are high-energy photons, but gamma rays typically originate from nuclear reactions, while X-rays are produced by electronic transitions.
  4. Why is lead used in radiation shielding? Lead is used for radiation shielding because it has a high atomic number and density, making it effective at attenuating gamma radiation.
