When are x-rays permitted to be performed?

X-rays are an important diagnostic tool in medicine, but their use is strictly regulated to ensure patient safety and minimize unnecessary exposure to radiation. Performing an X-ray requires a written authority from a licensed medical professional, such as a doctor. This ensures that the procedure is medically justified, takes into account the specific needs of the patient, and adheres to the principle of justification in radiation protection practices. Medical professionals evaluate the potential risks along with the clinical benefits prior to authorizing an X-ray, which is a critical component of responsible radiation use.

Relying solely on a patient’s request, or performing X-rays for routine check-ups without medical necessity, could lead to undue exposure that may not provide any meaningful benefit to the patient’s health. While research purposes play a role in advancing medical knowledge, such uses are bound by ethical standards and regulatory approvals. The key here is the requirement for a doctor's authority to ensure that any X-ray procedure aligns with appropriate medical guidelines and safety measures.
