Answer to Question #7483 Submitted to "Ask the Experts"

Category: Radiation Workers

The following question was answered by an expert in the appropriate field:


It's stated that annual education and training exposures are limited to 1 mSv. Does this recommendation only apply to students under the age of 18 or does this apply to all/any students in a radiography program?


While someone is potentially exposed and is in that situation because of an education program (such as radiography), the limit applies regardless of age. Any exposure that comes as a part of the program falls in the training limit.

If a person is in a program and also works part-time where he/she might be exposed to radiation, the limit in the program is 1 mSv and his/her limit for actual employment work is 50 mSv (assuming he/she is over 17).
