The minimum safe distance to maintain from the X-ray source is established based on principles of radiation protection. Keeping a distance of 6 feet is effective in reducing exposure to ionizing radiation. Radiation intensity follows the inverse square law, which states that as you double the distance from the source, the intensity of radiation decreases by a factor of four. Therefore, maintaining a distance of at least 6 feet significantly reduces the amount of radiation exposure received by healthcare workers and patients.

This distance not only minimizes risk but also aligns with safety guidelines and practices in healthcare environments where radiation is used. It is crucial for personnel to adhere to these safety measures to protect themselves and others from potential harm due to radiation exposure.
