Which term describes radiation that exits through the patient's body?

The term that describes radiation exiting through the patient's body is remnant radiation. This refers to the x-rays that have passed through the patient's tissue and have not been absorbed. Remnant radiation is crucial for creating the radiographic image because it is the radiation that reaches the image receptor, contributing to the visibility of anatomical structures and any potential abnormalities.

Exposure radiation typically refers to radiation that interacts with the patient but does not specify the radiation that exits, while dose radiation relates to the amount of radiation received by the patient rather than the radiation that passes through. Emergency radiation is not a standard term used in radiography and does not describe any specific type of radiation related to patient imaging. Therefore, remnant radiation is the correct term to indicate the radiation that emerges from the patient’s body after interaction with the x-ray beam.
