Reachback
The process of transmitting information from a ield deployed instrument to a lab or other
facility for further analysis.
Reactor-Grade Plutonium (RGPu)
Reactor-Grade Plutonium is a special mixture of
239
Pu,
240
Pu and other
Ú
, which
contains ≥19 %
240
Pu.
240
Pu has a high rate of spontaneous ission leading to an increased
number of
Ú
Neutrons
and bears the risk of premature starting chain reactions. Further
grades are

.
Real Time (RT)
The real or total time of a detection system comprises the
Ú
and the
Ú

Also known as:
Total Time, True Time
Region of Interest (ROI)
A selected subset of samples within a
identi ied for a particular purpose.

Remote Network Driver Interface Speci cation (RNDIS)
A Microsoft-proprietary protocol providing a virtual Ethernet connection used mostly via

Resolution
In spectroscopical application, the resolution gives a useful measure to estimate how well
two or more
Ú
can be distinguished. It is consequently de ined as the width of a peak
– usually the most prominent line at 661.65 keV of
137
Cs. Because there are various ways to
judge a peak width, it is a convention to use the
