Some of the terms used in radiological operations are:
(1) Entry time.
The time, measured from the time of burst, at which personnel enter a
radiation field to perform the mission.
Entry time is the time at which
exposure starts.
(2) Induced radiation.
Radiation near ground zero resulting from the capture of neutrons by various
substances. This will be found primarily in the soil, but it may also be
present in other objects.
(3) Militarily significant contamination.
Radioactive contamination capable of inflicting radiation doses which may
result in a reduction in combat effectiveness.
(4) Operation exposure guide.
The maximum amount of nuclear radiation, as determined by the commander, to
which troops may be exposed while performing the mission.
(5) Radiation unit of measure.
The unit of measurement of the absorbed dose of ionizing radiation
represents absorption of 100 ergs of nuclear or ionizing radiation per gram
of absorbing material or tissue. In conformance with the conversion to the
international metric system which has been adopted by NATO, centigray should
be written as cGy and pGy for microgray.
(6) Radiation dose.
The total amount of ionizing radiation absorbed by tissue or any other
absorbing material as commonly measured in centigray, cGy.
(7) Radiation dose rate.
The radiation dose absorbed per unit of time, commonly measured in cGy per
hour.
(8) Radiological agent.
Any of a family of radioactive substances that produce casualties by
emitting radiation.
Radiological agent refers to contamination other than
fallout or induced radiation.
