What are the three principles to protect oneself from radiation hazards?

• A. Distance, ventilation, time
• B. Distance, shielding, time
• C. Distance, retreat, protective gear
• D. Shielding, locality, time

Answer: (B)

The three principles to protect oneself from radiation hazards are distance, shielding, and time. Distance is critical because increasing the space between a person and the source of radiation significantly reduces exposure, following the inverse square law; as you double your distance from the source, the intensity of radiation exposure decreases to one-fourth. Shielding involves using materials that can absorb or block radiation, such as lead for gamma rays or plastic for beta particles. Effective shielding can prevent radiation from reaching the human body, thereby reducing potential harm. Time refers to minimizing the amount of time spent near a radiation source. By reducing the duration of exposure, the total radiation dose received can also be reduced. These three principles are fundamental in radiation safety protocols and help ensure the well-being of individuals who may work in environments with radiation exposure.
