What is the maximum allowable leakage radiation for x-ray tube housing at a distance of 1m from the target?

The maximum allowable leakage radiation for x-ray tube housing is regulated to ensure safety for both patients and healthcare workers. At a distance of 1 meter from the target, the regulatory standard is set at a maximum of 100 mR/hr (milliroentgens per hour). This limit is established to minimize exposure to radiation from the x-ray tube when it is not in use, addressing potential occupational exposure risks and ensuring compliance with safety protocols.

Adhering to this standard helps ensure that the radiation emitted during operation is kept as low as reasonably achievable (ALARA), promoting a safe working environment. This limit is based on extensive research and assessments of the potential health risks associated with radiation exposure, thereby supporting the principle of radiation protection in medical imaging.
