In terms of radiation exposure, what is considered the 'go-to' strategy for minimizing risks?

The strategy of using time, distance, and shielding is foundational in minimizing radiation exposure and is essential in radiation safety practices. This approach is often summarized as the "principles of radiation protection."

Time refers to the duration a person is exposed to radiation; reducing the time spent near a source of radiation effectively decreases the total dose received. Distance relates to the space between the source of radiation and the individual; increasing this distance can significantly lower exposure levels due to the inverse square law, which states that radiation intensity decreases with the square of the distance from the source. Shielding involves the use of barriers made from materials that can absorb or block radiation, such as lead or concrete, providing an additional layer of protection.

These three components work synergistically to limit exposure safely and effectively, making them a comprehensive strategy recognized universally in the field of radiology and fluoroscopy. By implementing these principles, radiologic technologists and other health care professionals can ensure they maintain exposures at the lowest possible levels, thereby safeguarding their health and the health of patients.
