What is the best way to protect against the effect of expose to are by time distance and shielding?

To protect against exposure to radiation, the best strategies are time, distance, and shielding. Reducing the time spent near a radiation source minimizes exposure, while increasing distance from the source significantly decreases radiation intensity due to the inverse square law. Additionally, using appropriate shielding materials, such as lead or concrete, can effectively absorb or block radiation, further enhancing safety. Combining these methods provides a comprehensive approach to radiation protection.
