Under what conditions does CA law require appropriate structural shielding for mobile x-ray equipment?

The requirement for appropriate structural shielding in California law pertains to the usage of mobile x-ray equipment. When mobile x-ray equipment is used routinely in one location, there is a continuous potential for radiation exposure to staff and patients in that environment. This consistent usage necessitates adequate shielding to protect against the scattered radiation that can occur during x-ray procedures.

When mobile equipment is merely moved from one location to another, or used sporadically in areas such as operating rooms or intensive care units, it may not always justify the same level of structural shielding, especially if the use does not result in prolonged exposure or if adequate safety measures are already in place. Therefore, the specific emphasis on "routine" usage stresses a higher standard of care in shielding to safeguard the health and safety of individuals near the operation of the x-ray equipment.
