How many take time to remove secondary radiation after xray done?

The time it takes to remove secondary radiation after an X-ray is typically immediate, as secondary radiation, which is scattered radiation produced when the primary X-ray beam interacts with matter, diminishes rapidly. The exposure to secondary radiation usually decreases significantly within seconds after the X-ray exposure is stopped. However, the actual removal of residual radiation in the environment can vary based on factors such as room ventilation and shielding. Overall, the concern for secondary radiation is minimal once the procedure is complete.
