FLIR Detection D. Glossary
Röntgen Equivalent in Man (rem)
The röntgen equivalent in man is an old unit of radiation
Ú
Dose . (
Ú
Sievert )
100 rem = 1 Sv
The continued use of rem is “strongly discouraged” by the U.S. National Institute of Standards
and Technology.
RT
Ú
Real Time
Scintillation Counter
A device to measure
Ú
Ionizing Radiation by amplifying the light emitted from a
Ú
Scintillator
with a
Ú
Photo Multiplier Tube and quantifying the result.
Scintillator
A material emitting a lash of light when it absorbs
Ú
Ionizing Radiation .
Semiconductor Radiation Detector
A semiconductor (for example
Ú
Germanium or
Ú
Cadmium Zinc Telluride ) placed between
two electrodes registering electric pulses resulting from the travel of free electrons pro-
duced by incident
Ú
Gamma Radiation . The number of free electrons is proportional to the
radiation’s energy.
SI ( Système International d’Unités )
A metric and decimal system of units, standardized by the Bureau International des Poids et
Mesures (International Bureau of Weights and Measures).
Also known as: International System of Units
SI Pre xes
Ú
Unit Pre ixes
Sievert (Sv)
The
Ú
SI derived unit of dose equivalent. It attempts to re lect the biological effects of
Ú
Ionizing Radiation as opposed to the physical aspects, which are characterized by the
Ú
Absorbed Dose (
Ú
Gray ).
1 Sv = 1
J
kg
= 1
m
s
For
Ú
Gamma Radiation , these are the same base units as the
Ú
Gray . To avoid confusion, do
not use J/kg but always Gy for the absorbed dose and Sv for the dose equivalent.
SIM
Subscriber Identity Module, used for example in mobile phones.
Sodium Iodide (NaI)
Substance to build
Ú
Scintillation Counters .
SOP
Ú
