NCRP 49 Occupancy Factors

[malewandowski1@mmm.com]

Here is a chance to educate a simpleton.  

While reviewing NCRP 49, Structural Shielding Design and Evaluation for
Medical Use of X Rays and Gamma Rays of Energies up to 10 MeV, Table 4 -
Occupancy factors for non-occupationally exposed persons, I developed
the following question.

What is the difference between a "rest room" (T=1/4) and a "toilet"
(T=1/16)?

Thanks for your thoughts,
