over an area from one position. It is necessary to move the CAM
around the area, carrying out a complete reconnaissance, if a proper

Components.
a. Carrying Case Assembly.
Provides storage for all equipment (Figure 4-25).
b. Chemical Agent Monitor.
Case that contains a battery to power the CAM, a liquid crystal
display (LCD) to show contamination concentration levels and
malfunction information, a pneumatic system to draw in samples, a cell
containing beta radiation source (10 millicuries of Nickel-63) to
detect the presence of agent contamination, and a printed circuit
board flexible wiring assembly containing a microcomputer to control
operation of the CAM and detection of agents (Figure 4-25).
