What is leakage radiation?

Leakage radiation refers specifically to radiation that escapes from the X-ray tube housing in directions not intended for the useful beam. In the context of X-ray equipment, the "useful beam" is the directed radiation that is specifically aimed at the patient to generate diagnostic images.

Radiation can find its way through any imperfections or gaps in the shielding of the tube housing, which can pose a risk to staff and others in the vicinity. Regulations and standards are in place to limit this type of radiation exposure, ensuring safe operation in medical environments. Therefore, the essence of leakage radiation is that it is unwanted and potentially harmful radiation that exits the equipment in directions that do not contribute to the diagnostic process.
