NRC requirements on retention of film

[loesch@viper.eh.doe.gov (Robert M. Loesch)]

We at DOE are involved in discussions with National Archives on the recommended
retention times for processed film (not the recorded results from).  Would 
appreciate hearing from NRC licensees about any specifics incorporated into
licenses or technical specifications.  All I could find in Part 20 was in
20.2106(f) which requires maintaining records of individual monitoring
results until the Commission terminates the license requiring the record.
However, it doesn't specifically reference processed file.
