What is the safe limit for barrication during radiography?

0.25 mSv

According to the International Atomic Energy Agency (IAEA), the safe limit for barrication during radiography is 0.25 mSv (millisieverts) per hour. This limit is based on the assumption that the radiographer is exposed to the radiation for a period of one hour. If the radiographer is exposed to the radiation for a shorter period of time, the safe limit will be higher.
