Which statement describes the Shielding concept in radiation protection?

• A. Shielding should be worn or inserted between radiation sources and exposed
• B. Time of exposure should be kept to a minimum
• C. Distance should be minimized
• D. Dosimeters should be worn at all times

Answer: (A)

Shielding in radiation protection means placing protective barriers between the radiation source and anyone who could be exposed so that the radiation is absorbed or scattered before it reaches them. This reduces the dose because materials like lead or concrete absorb photons as they pass through, and the amount absorbed depends on the material, its thickness, and the energy of the radiation. The statement that best describes this concept is that shielding should be placed between radiation sources and the exposed individuals, using appropriate barriers or protective apparel to block or reduce the radiation. This approach is different from reducing exposure by time or distance. Reducing time means spending less time near the source, and increasing distance means moving farther away from the source to lower exposure. Dosimeters relate to monitoring how much radiation has been received, not to actively reducing dose.
