FLIR Detection D. Glossary
Ionization depends on the energy of radiation, not on the number of particles or the wave-
length. Roughly speaking, particles or photons with energies above a few ÚElectron Volts are
ionizing.

Ionizing Radiation can cause serious damage when absorbed by living tissue, and is
therefore a health hazard.
IP ÚInternet Protocol
IP Address
A unique numerical label that is assigned to devices participating in an ÚInternet Protocol-
based computer network. Usually it is a 32-bit number written in four 8-bit bytes, for example
192.168.10.199
. It is used to identify hosts or network interfaces and to address locations.

Isobar
Different ÚNuclides having the same ÚMass Number, for example
40
18
Ar and
40
19
K or
72
36
Kr and
72
34
Se.
Isomer
An excited state in a ÚNucleus having a very long ÚHalf Life compared to other excited states:
at least a µs or ms. Some isomers expose a much longer half life so they are called metastable
(m), for example
99m
Tc with a half life of about 6 h.
