When shall a radiographic expose device be locked to prevent unauthorized removal?

A radiographic expose device should be locked to prevent unauthorized removal at times when it is not under direct visual surveillance. This practice is crucial for ensuring safety and security, as it helps to minimize the risk of accidental exposure or theft of the device, which contains radioactive materials. Locking the device when there is no visual supervision ensures that only authorized personnel can access or move the device, thereby maintaining control over its use and protecting individuals and the public from radiation hazards.

In environments where radiographic equipment is handled, it is paramount to establish protocols to safeguard such devices when they are not being actively monitored. The act of locking the device serves as a physical barrier to unauthorized access, which is a fundamental aspect of radiation safety protocols.

While there are circumstances under which the equipment might be locked, such as being utilized at temporary job sites or upon request from the Radiation Safety Officer (RSO), these situations may not always directly relate to the immediate necessity of securing the device when it is unattended. Hence, the emphasis on locking the device during periods of non-surveillance is a proactive safety measure that aligns with regulatory standards and best practices in radiation safety.
