Final answer:
It is true that a fully enclosed radiology room is necessary for limiting radiation exposure. Shielding methods, increasing distance, and reducing exposure time are key for safety in environments where X-rays are used.
Step-by-step explanation:
The statement that the radiology room must be in a fully enclosed room to limit radiation exposure to passersby is true. This is because X-rays carry considerably more energy than visible light and can harm living tissues by ionizing molecules and damaging cellular structures which can potentially lead to cancer. Hence, shielding such as lead-lined walls and doors, use of lead aprons, and other forms of protection are necessary to protect both the patient and healthcare workers from unnecessary exposure. Measures such as increasing distance from the radiation source, minimizing exposure time, and using imaging technologies with shorter duration or isotopes with short half-lives are implemented to limit radiation doses. Occupations involving frequent exposure to radiation, like radiology technicians, must undertake specific precautionary methods to mitigate the associated risks.
