Entry into radiography areas requires permission from the radiography crew leader and direct protection by a lead radiographer who is RPC yellow or green qualified. Which option best matches this requirement?

• A. Radiography crew leader / Lead radiographer (RPC yellow or green qualified)
• B. Safety officer / Nurse
• C. Site supervisor / Doctor
• D. HR manager / Safety trainer

Answer: (A)

Entry into radiography areas must be tightly controlled to minimize exposure and ensure protection. The two pieces of this control are clear: first, someone in charge must authorize entry, and second, there must be direct protection by a trained lead radiographer who has the proper RPC qualification.

Having the radiography crew leader grant permission ensures that all tasks, access, and shielding are planned and supervised by the person responsible for the radiography operation. The lead radiographer with RPC yellow or green qualification provides direct protection on site, overseeing the radiographic work, ensuring proper shielding, dose monitoring, and adherence to protection procedures. This combination guarantees both authorization and hands-on protection during entry.

Other roles like safety officers, nurses, site supervisors, doctors, HR managers, or safety trainers may contribute to safety in broader contexts, but they do not provide the specific entry authorization and direct radiological protection required for entering radiography areas.
