Final answer:
X-rays for medical imaging are used only in limited amounts due to their potential harm to the body. The principle of ALARA is followed to minimize radiation exposure, and non-ionizing imaging techniques are used as alternatives whenever possible.
Step-by-step explanation:
X-rays for medical imaging are used only in limited amounts because they can be harmful to the body. X-rays are a form of ionizing radiation, which carries enough energy to remove electrons from atoms and can damage cells and DNA. To minimize the potential risks, healthcare professionals limit the use of X-rays to when they are necessary for diagnosing or monitoring certain conditions.
Healthcare providers follow the principle of ALARA (As Low As Reasonably Achievable) when it comes to radiation exposure. This means that they strive to use the lowest effective dose of radiation to obtain the needed medical information. X-ray imaging is typically used when other non-ionizing imaging techniques, such as ultrasound or MRI, cannot provide the necessary diagnostic information.
Thanks to advancements in technology, healthcare professionals have access to alternative imaging techniques that do not involve ionizing radiation. These alternatives are utilized whenever possible to minimize the risks associated with X-ray exposure, especially in sensitive populations such as children and pregnant women.
