In radiation protection, what does TDS stand for?

• A. Time
• B. Distance
• C. Shielding
• D. Time, Distance, and Shielding

Answer: (D)

The main idea is that protecting people from radiation relies on three controls. Time, Distance, and Shielding are the three fundamental levers you use to reduce exposure. Time means spending less time near the source, which lowers dose proportional to how long you’re exposed. Distance means standing farther away from the source, since exposure drops off quickly with distance (the inverse square relationship). Shielding means using appropriate barriers to absorb or attenuate the radiation before it reaches you. Together, these three strategies form the core approach to radiation protection, which is why TDS stands for Time, Distance, and Shielding. The other options describe only one aspect, which doesn’t capture the full protective approach.
