Don,
I do not base my judgement on the LNT or what I think
about it.  I consider what is actions are need to get
the work done and keep down radiation exposures.  I
thought that is what ALARA is all about.

If spending $100 for shielding, that is a good
investment as the material could be used again.  If
having a worker receive some radiation exposure in
completing a job, that is what their job is.  The
issue I think is whether or not anything can be done
to reduce exposure.  

By the way, on the first nuclear powered submarines,
e.g, USS Nautilus SSN–571, etc., there was a 20 second
stay-time for crew members as they went aft over the
reactor. There was no shielded tunnel over the reactor
compartment. 

To tell you the truth, the only time I think about the
LNT is when I get messages from this list server.  Do
you think about the LNT a lot?
