FLIR Detection D. Glossary
Geiger–Müller Tube (GM Tube)
A device to detect
Ú
Ionizing Radiation consisting of a tube illed with low-pressure noble and
halogene gas in a strong electric ield. Incident radiation produces
Ú
Ions which can be mea-
sured as electric current between the electrodes.
Germanium (Ge)
A substance used in high-precision
Ú
Semiconductor Radiation Detectors for
Ú
Gamma Radi-
ation .
Global Positioning System (GPS)
A constellation of satellites sending microwave signals which enable receivers to determine
the time, their location, speed, and direction.
Also known as: Navstar Global Positioning System

Gray (Gy)
The gray is the
Ú
SI derived unit of
Ú
Absorbed Dose due to
Ú
Ionizing Radiation . One gray is
the absorption of one joule of energy, in the form of ionizing radiation, by one kilogram of
matter.
1 Gy = 1
J
kg
= 1
m
s
For
Ú
Gamma Radiation , these are the same base units as the
Ú
Sievert . To avoid confusion,
do no not use J/kg but always Gy for the absorbed dose and Sv for the
Ú
Equivalent Dose .
Greenwich Mean Time (GMT)
Originally the mean solar time at the Royal Observatory in Greenwich, London. It is commonly
but imprecisely used synonymously with
Ú
Coordinated Universal Time when referring to
time zones.
Gy
Ú
Gray
Half Life
The duration it takes for a substance undergoing
Ú
Decay to decrease by half.
HAZMAT, Hazmat, HazMat
Hazardous materials and items, dangerous goods.
