However, the nature of radiation andBW and CW agents makes it difficult to detect andidentify them. Here are some examples.You know a nuclear attack is taking place becauseyou can see it, hear it, and feel it. But, you can’t see thenuclear radiation. Nuclear radiation is just as deadlyover a period of time as the blast itself. A biological andchemical attack can be just as invisible. You might notknow about them until it’s too late. Because CBRattacks might be invisible, you need to recognizesymptoms of radiation and BW and CW contamination.SURVEY TEAMSAfter a CW, BW, or nuclear attack, survey teams gothrough the ship to determine the extent and location ofany contamination. Rapid detection and identificationare vital so that effective defense measures may be takenimmediately. A survey team, or monitoring party,consists of a minimum of three people—a monitor, arecorder, and a messenger.The monitor is in charge of the party. The monitorcarries high-range and low-range survey meters. Themonitor is responsible for the safety of the team and fordetermining intensities and locations of contamination.The recorder maintains a record of intensityreadings (obtained by the monitor), time of thereadings, location of the hazardous areas, and specifichazards. Also, the recorder may act as a marker, usingline to rope off hazardous areas and chalk to mark onbulkheads and decks the intensities of contaminationfound during the survey.The messenger reports to damage control central(DCC) the contaminated areas and the readingsobtained by the monitor. In DCC, personnel plot thereports from the various teams to get a general outline ofcontaminated areas, to pinpoint hot spots (areas ofhigher-than-average intensities), and to establish staytimes for specific areas (fig. 13-5).13-13Student Notes:
