     Good luck!  There isn't a defensible reference (especially for the 20 
     to 25% numbers you quote).  There are some studies going on, we're 
     doing one this summer on protective clothing and respirators, but 
     nothing like what you want exists.  If you must use some type of 
     efficiency factor (or degradation factor), base it on physiological 
     response to the change in environmental conditions.  There's plenty of 
     data for that.
     
     Also, I suggest you talk to your Fluor Daniel brethren at the Fernald 
     site.  They have some great stuff on protective clothing.
     
     As always, these are solely my opinions and do not necessarily reflect 
     the opinions of my employer.

     Dear Radsafers,
     
     I am looking for a reference that estimates the decrease in a worker's 
     efficiency while wearing respiratory protection.  One source indicates 
     that the time needed to finish work is increased by between 20 to 25%. 
     I am developing a training module addressing ALARA consideration for 
     respirator use.
     
     Please respond to me directly at:

     Takk!
