Whew, its been a long week. But, its Friday!

Esteemed Radsafers, a few questions regarding surveys of the 
interiors, not exterior, of pipes and ducts:

1. What instruments, commercially available or otherwise, have you 
used? Any comments, good or bad?

2. If it was done quantitatively, how did you determine the 
efficiencies?

3. Any general thoughts on this subject e.g. problems, good 
references etc?

Thanks

Paul Frame

Bonus question. Does anyone know anything about a navy(?) 
radiation(?) symbol that takes the form of a trident with a wavy line 
(gamma ray?) heading off at right angles from one of the prongs?
