(1)        Hazard Groups based upon Annual Limits of Intake (ALI) from ICRP #30 and WAC 246-221-290.

(2)        1 mCi = 37 MBq

(3)        Laboratories only storing radioactive materials will be considered lab class A. 

Notification of the storage status must be made directly to the RSO.                                                                                             09/24/08
