Final answer:
The reopening of flights by a Supervisor and the operation of ramp scanners like those in OTIS PWB depend on specific airport or airline procedures. When related to radiation detectors, individuals with recent medical treatments involving radioactive materials may need special permission to fly.
Step-by-step explanation:
Whether all flights need to be reopened by a Supervisor and if the ramp scanners will continue to show information as they currently do in OTIS PWB is a specific procedural question likely related to airport operations or airline management.
Generally, the protocols for flight operations, including the management of flight statuses, would depend on the specific policies and systems in place at an airline or airport. When related to radiation detectors and particularly in the context of passengers who have recently undergone medical treatments involving radioactive materials, such individuals may need special clearance to travel due to potential false alarms at security screenings.
They can trigger radiation detectors because of the substances present in their body, necessitating the need for special permission to fly on commercial airlines.
