security of rad material

["George Rawls" <george@pliny.ehs.ufl.edu>]

At various times in this university research setting, private 
contractors may be hired to perform functions which require their 
entry into authorized use areas which store radioactive material, 
sealed and unsealed sources.  These contracts are usually set up by 
Physical Plant and are sometimes performed at night and on weekends 
when the labs are locked and unattended.

I am speaking here of the entry by private contractor personnel into 
these labs when the labs are unattended(night and weekend).  Since 
many , if not most of these labs rely only upon the locked outer 
door(s) for security of rad material, the question is:

In light of the NRC security regulations, should these contractor 
personnel be allowed unescorted entry into these storage/use areas?

There are two views here:

1. Train them to stay away from posted areas and don't touch anything 
in those areas and let them go unescorted.

2. You can train for radiation protection but you can't train for 
security concerns.  These contractor personnel must be accompanied 
into the areas of concern by a university employee due to security 
regs.

I hope for  a good response to this since I suspect that 
there are varying views out there for diferent security scenarios.  I 
will be glad to summarize the answers later if anyone calls upon me 
to do so.
