How can radiation dose be effectively reduced?

Moving farther from the source of radiation is an effective way to reduce radiation dose due to the principles of radiation exposure. As the distance from a radiation source increases, the intensity of the radiation received diminishes according to the inverse square law. This principle states that the intensity of radiation is inversely proportional to the square of the distance from the source. Therefore, doubling the distance from the source results in a fourfold reduction in radiation exposure.

By maximizing distance, individuals can significantly lower their risk of radiation exposure, making it a fundamental practice in radiation safety. While other methods like wearing protective clothing, using lead shielding, or other physical barriers can help, increasing distance is one of the most straightforward and effective measures to minimize radiation dose.
