LaBr probe being used with Canberra's Inspector-1000 for portable isotope identification and quantification
are an integral part of many safeguards systems. In general, we
use radiation detectors
for all of the following:
determining if radiation and/or radioactive material is
An example of this would be survey meters or
portal monitors .
determining what isotopes are
generating the radiation that is present.
An example of this would be most
handheld isotope identifiers .
determining the amount of each isotope present.
An example of this would be nuclear material accountancy
Each of these levels gets progressively more difficult to
accurately achieve. We will consider each of these levels of
measurement in this module, but for safeguards purposes we are most
interested in being able to do quantification. In the case of
nuclear materials, we must use the unique properties of these
materials to allow us to detect, identify, and quantify the
materials. The nuclear materials of primary interest to us are uranium (U) and plutonium (Pu). We are also
interested in americium (Am), curium (Cm), neptunium (Np), and californium (Cf).
