To protect yourself from radiation exposure, you should do all of the following EXCEPT:

• A. Increase distance from the source
• B. Wear a mask to prevent respiratory exposure
• C. Use shielding
• D. Limit time near the source

Answer: (B)

Radiation protection hinges on three primary actions: increase distance from the source, limit the time you spend near it, and use shielding to attenuate the radiation. Moving farther away reduces dose due to the inverse-square relationship of radiation intensity. Limiting time near the source lessens the total accumulated dose. Shielding provides a barrier that absorbs or deflects the radiation before it reaches you, with effectiveness depending on the energy of the radiation and the material used. A mask does not significantly reduce exposure to external radiation like gamma rays, which is why it isn’t considered a primary protective measure. It might help only if there is a specific inhalation risk from contaminated particles, but for general radiation exposure, distance, time, and shielding are the effective protections.
