Re: Ion chamber versus GM

["Jesse H. Coleman" <radshoals@airnet.net>]

I too have seen this distinction between radiation detectors and
measuring devices.  Your use of the ion chamber seems OK to me.
To prevent a violation, consider these sources:

1 - Radiation Detection and Measuriment by Knoll, 1979, on page
151:  "The term ionization chamber has conventionally come to be
used exclusively for the type of detector ..."

2 - Nuclear Radiation Detection by Price, Second edition, 1964 
sorry old book, but still good), on page 44 starts a section
called Ionization Chamber Detectors.

3 - Principles of Nuclear Radiation Detection, by Eicholtz and
Poston, 1982, on page 100, "Two broad classifications of
ionization chambers are usually assigned in the discussion of
radiation detectors of this type."

If you call an ion chamber a detector, you are in good company.
