Worker Deficiency in Respirators

[Brian_L_Killand@RL.gov]

     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!
