The radiographers for bedside X-ray photography, DR, and CT examinations working in the isolation area are recommended to take a 2 + 2 working mode, due to the possibility of closely contacting with the confirmed patients. In the 2 + 2 working mode, the radiographers should complete a first period of 14 workdays in the isolation area, and subsequently take a second period of 14 days in a specific dedicated isolation ward for supervised medical observation before returning to normal work.
