What is the main reason for keeping radiation doses as low as reasonably achievable?

The primary reason for keeping radiation doses as low as reasonably achievable (ALARA) is to protect patient health. The concept of ALARA is rooted in the understanding that while radiation can be a valuable tool in medical imaging and treatment, excessive exposure can lead to adverse health outcomes, including increased risks of cancer and other radiation-induced conditions. By ensuring that radiation doses are minimized without compromising the diagnostic utility of the imaging procedure, healthcare providers prioritize the safety and well-being of patients.

This approach emphasizes the importance of optimizing imaging protocols and using the lowest effective dose necessary to achieve the required diagnostic information, thereby balancing the need for clinical efficacy with patient safety. Protecting patient health is a fundamental ethical principle in medicine and underscores the commitment to patient care in the practice of fluoroscopy and radiology.
