Date of Review
: 28 October 2018
: 25 October 2021
The following tables list the National Diagnostic Reference Levels (NDRLs) for the State of Qatar. These NDRL values are selected from several national and regional RDLs and approved by Qatar Medical Physicists Society (QaMPS) in 2018. They should be considered by employers when setting their local DRLs as required by the Executive Regulations (Dec. 4 2003) of the Radiation Protection Law 31 (2002).
