Requirements for adhering to the IAEA's Fundamental Safety Principles (SF-1) are laid forth in the IAEA's General Safety Requirements. The establishment of requirements for the protections of workers exposed to sources of radiation are found in Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards, General Safety Requirements, No. GSR Part 3. These safety standards establish the need for the monitoring of occupational exposure to external radiation sources for workers.

The IAEA has developed training material on the assessment of occupational exposure due to external radiation sources which covers the objectives, techniques, and evaluation of monitoring radiation exposure. This course is broken into twelve modules that should give users a preliminary understanding of the need and methods used for dose monitoring during normal occupational exposure and accidental exposure scenarios. ​

Approved training packages may be copied, distributed, displayed, incorporated in customized presentations and used for non-commercial use as long as the source of the material is referenced to the IAEA approved training package.
