Chris,

ONLY if you are under NRC limits, or an Agreement State. Those 
states who have not adopted annual limits still maintain quarterly 
limits, and, there is NO 15 rem/yr eye dose limit. These states use 
the 1.25 rem/qtr eye limit (based on definition of whole body.

I beg to differ with your interpretation. Also, 10CFR20 does not 
apply to radiation generating machines, unless the states have 
adopted the 10CFR20 philosophy, which most have not.
