CONTAMINATION, DETECTION, AND
Learning Objectives: When you finish this chapter,
you will be able to
Identify the purpose of CBR monitoring and
Identify the markers used to indicate CBR
Recall the purpose of the markers used to
indicate CBR contamination.
For a ship or station to retain its offensive power and
carry out its mission, immediate detection and
identification of radiation and BW and CW agents are of
great importance. However, the nature of radiation and
BW and CW agents makes it difficult to detect and
identify them. Here are some examples.
You know a nuclear attack is taking place because
you can see it, hear it, and feel it. But, you cant see the
nuclear radiation. Nuclear radiation is just as deadly
over a period of time as the blast itself. A biological and
chemical attack can be just as invisible. You might not
know about them until its too late. Because CBR
attacks might be invisible, you need to recognize
symptoms of radiation and BW and CW contamination.
After a CW, BW, or nuclear attack, survey teams go
through the ship to determine the extent and location of
any contamination. Rapid detection and identification
are vital so that effective defense measures may be taken
immediately. A survey team, or monitoring party,
consists of a minimum of three peoplea monitor, a
recorder, and a messenger.
The monitor is in charge of the party. The monitor
carries high-range and low-range survey meters. The
monitor is responsible for the safety of the team and for
determining intensities and locations of contamination.
The recorder maintains a record of intensity
readings (obtained by the monitor), time of the
readings, location of the hazardous areas, and specific
hazards. Also, the recorder may act as a marker, using
line to rope off hazardous areas and chalk to mark on
bulkheads and decks the intensities of contamination
found during the survey.
The messenger reports to damage control central
(DCC) the contaminated areas and the readings
obtained by the monitor. In DCC, personnel plot the
reports from the various teams to get a general outline of
contaminated areas, to pinpoint hot spots (areas of
higher-than-average intensities), and to establish stay
times for specific areas (fig. 13-5).
