Gamma rays can be blocked effectively by dense materials. Lead is commonly used due to its high density and atomic number, which absorb and scatter the gamma rays. Concrete and other heavy metals are also effective blockers, providing layers of protection in radiation shielding applications.

FAQs & Answers

  1. What is radiation shielding? Radiation shielding involves using materials to protect against harmful radiation by absorbing or scattering it.
  2. Why is lead used for blocking gamma rays? Lead is used because of its high density and atomic number, which make it effective at absorbing and scattering gamma rays.
  3. What other materials can block gamma rays? In addition to lead, dense concrete and heavy metals are also effective at blocking gamma rays.
  4. How thick does a wall need to be to stop gamma rays? The thickness required to stop gamma rays depends on the energy of the gamma radiation and the material used; denser materials require less thickness.
