Final answer:
True, the principles of time, distance, and shielding are critical for ensuring the safety of both the patient and the radiographer during an X-ray procedure, as they help to minimize radiation exposure.
Step-by-step explanation:
The statement is True: The basic principles of time, distance, and shielding can indeed be applied for the safety of both the patient and the radiographer in the context of medical imaging, such as when an X-ray is taken. The use of a lead apron placed over the dental patient provides shielding that absorbs radiation, thereby limiting exposure to non-targeted tissue.
Additionally, the technician is protected by maintaining a greater distance from the radiation source, which reduces exposure since radiation intensity decreases with distance. Lastly, the use of fast films in modern medical imaging limits the time required to obtain images, which accordingly reduces the exposure of the imaged tissue.
