Final answer:
True. The more efficient a grid is at absorbing scatter, the lower the image receptor exposure.
Step-by-step explanation:
True. The more efficient a grid is at absorbing scatter, the lower the image receptor exposure. This is because when a grid absorbs scatter radiation, it reduces the amount of scatter reaching the image receptor, resulting in a cleaner and more accurate image. A grid consists of lead strips that are placed between the patient and the image receptor.
