      There's a fellow sniffing around radsafe searching for quick and easy

answers about radiation units.  I'd recommend he get a copy

of Herman Cember's book on Introductory Health Physics and read the 

first 5-10 Chapters.  Quality factors can equal one for photons, but are highly

variable for real world neutrons.  Read the book or consult with a

real Health Physicist.  That's what we're here for.


     As for bubble dosimeters, Dr. Apfel of Apfel Enterprises (or whatever his 

firm is called) has advertisements in the Health Physics journal.  The Ing

fellow (from Chalk River, Canada???) is also involved with bubble 

dosimeters.  Their products appear to be very viable (over wide energy

ranges).
