What is the maximum allowable leakage radiation from the x-ray tube housing?

The correct response regarding the maximum allowable leakage radiation from the x-ray tube housing is based on established safety standards and regulations. The limit set for leakage radiation is crucial for ensuring patient and staff safety from unnecessary exposure to radiation.

The maximum allowable leakage radiation from the x-ray tube housing is 1 mGy/hr at a distance of 1 meter. This standard is instituted to minimize exposure risks and maintain a safe working environment in medical imaging settings. By adhering to this limit, facilities can ensure effective shielding and safety measures are in place, protecting both patients and staff from excessive radiation exposure during routine operations.

This guideline aligns with recommendations from organizations such as the International Commission on Radiological Protection (ICRP) and the National Council on Radiation Protection & Measurements (NCRP), which emphasize the importance of keeping radiation exposure as low as reasonably achievable (ALARA). Adhering to this standard helps mitigate potential long-term health risks associated with radiation exposure.
