64E-5.6332. Decay of Strontium-90 Sources for Ophthalmic Treatments

(1) Only an authorized medical physicist or authorized user qualified to perform procedures described in subsection 64E-5.632(2), F.A.C., shall calculate the activity of each strontium-90 source that is used to determine the treatment times for ophthalmic treatments. The decay must be based on the activity determined under Rule 64E-5.6331, F.A.C. (2) For each Strontium 90 source the licensee shall retain the following records for the life of the source: (a) The date and activity of the source as determined under Rule 64E-5.6331, F.A.C.; and, (b) For each decay calculation, the date and the source activity as determined under Rule 64E-5.6332, F.A.C.
