If you increase your distance from a radiation source, what happens to your radiation exposure?

• A. Your exposure increases
• B. Your exposure decreases
• C. Your exposure remains the same
• D. It varies on shielding

Answer: (B)

Increasing your distance from a radiation source leads to a decrease in radiation exposure due to the inverse square law of radiation. This scientific principle states that the intensity of radiation decreases with the square of the distance from the source. In simpler terms, as you double your distance from the radiation source, your exposure reduces to a quarter of what it was at the original distance. This is because the radiation spreads out over a larger area as it travels away from the source, resulting in less exposure at greater distances. Consequently, maintaining or increasing distance from a source of radiation is a key principle in radiation safety and protection strategies to minimize exposure.
