Efficiency Bulletins

EB 16-04: Source Checking Personnel and Tool Contamination Monitors

This bulletin will result in greater efficiency by reducing the frequency of personnel radiation monitor checks from daily to weekly at nuclear power plants’ radiologically controlled area exits. 

As a result of this bulletin, contamination monitors with enhanced technology at the exits of radiologically controlled areas (such as the reactor building) will be source-checked weekly instead of daily. This will align personnel radiation monitor checks with industry guidelines for radiological protection at nuclear power plants and also take advantage of newer technologies capable of performing self-checks.

Target implementation date: June 2016.
