Violations of these export laws are subject to sever criminal penalties. DISTRIBUTION STATEMENT C: Distribution authorized to U.S. Government agencies and their contractors to protect technical or operational information. This determination was made on 12 November, 1991.

HEADQUARTERS, DEPARTMENT OF THE ARMY 9 JUNE 1998 TM 3-6665-343-23&P WARNING RADIATION HAZARD NICKEL-63 (Ni-63) Wipe test must be performed before and after any maintenance or testing of CAM. Contamination can become airborne by heated air and smoke from fire. Stand upwind of fire to avoid inhalation of possible contamination. The Chemical Agent Monitor (CAM) contains a beta radiation source in the quantity which requires a Nuclear Regulatory Commission (NRC) license to possess items which contain the source. The CAM contains 10 millicuries of Nickel-63. The Nickel-63 plated cylinder is the source which ionizes chemical agents allowing for their detection. If the CAM is lost or stolen, notify the NBC Officer/NCO and the local Radiation Protection Officer (RPO) immediately. Lost or stolen CAMs are reportable to the Nuclear Regulatory Commission (NRC) by the license holder. Report must be made through the local RPO to the Armament and Chemical Acquisition and Logistics Activity (ACALA) Safety Office, DSN 793-2965/2995/6228. The source is totally enclosed and protected by the CAM case. However the CAM is potentially dangerous if broken. SAFETY PRECAUTIONS 1. 2. Handle the CAM carefully. If CAM case is broken or cracked, inform the NBC Officer/NCO, and if available, the local Radiation Protection Officer (RPO). A CAM damaged beyond the repair capability of direct support should be wrapped in a plastic bag and shipped in original packing container, if available, to depot maintenance for repair. If skin contact is made with any area thought to be contaminated with Nickel-63, wash immediately with nonabrasive soap and water. Follow safety procedures for storage, shipment, and disposal in accordance with this manual, local regulations, AR 710-3 and AR 385-11. 3. 4. a TM 3-6665-343-23&P WARNING LITHIUM SULFUR DIOXIDE BATTERIES: Do not attempt to decontaminate CAM batteries. Dispose of batteries according to TB 43-0130 and local Standing Operating Procedures (SOP). FLAMMABLE AND CORROSIVE HAZARD Lithium sulfur dioxide batteries contain lithium, sulfur dioxide and an electrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammable and highly corrosive. Do not immerse in water or decon solution, crush, or burn batteries. Do not attempt to recharge batteries or store at temperatures above 158°F (70°C). If a battery is mishandled or misused, the lithium may rapidly vent out, carrying with it the sulfur dioxide gas and the electrolyte, and it may heat up. If this happens, stay away until the smell of sulfur is gone. If you have to move the battery, move it outside by using a shovel or long tongs. Wear suitable protection when handling suspect batteries. A rapidly venting battery may create an explosive and corrosive hazard which may cause damage to skin and eyes. If skin or eyes come in contact with the electrolyte, wash thoroughly with generous amounts of water and seek medical attention. Dispose of batteries according to TB 43-0130 and local SOP. WARNING DANGER-HIGH VOLTAGE-1000 VOLTS DC 1000 volts DC is present on the Printed Circuit Board (PCB) when monitor case is removed. Danger of electrical shock exists if PCB is touched while CAM is operating. CAUTION Do not decontaminate CAM or its accessories with M258A1 or M280 Decontamination Kits. These kits may cause false positives and temporarily render the CAM inoperative. FIRST AID For first aid information, refer to FM 1-11. b TM 3-6665-343-23&P TECHNICAL MANUAL No. 3-6665-343-23&P HEADQUARTERS Department of the Army Washington, DC, 9 June 1998 UNIT AND DIRECT SUPPORT MAINTENANCE MANUAL (INCLUDING REPAIR PARTS AND SPECIAL TOOLS LIST) FOR IMPROVED CHEMICAL AGENT MONITOR (ICAM) NSN 6665-01-357-8502 (EIC:5AB) REPORTING ERRORS AND RECOMMENDING IMPROVEMENTS You can help improve this manual.

These charged particles are used to produce an electronic signal by means of a process called Ion Mobility Spectrometry (IMS). Acetone vapor is introduced into the closed circulatory system to stabilize the response of the CAM in the nerve agent mode. The G/H mode push button switch reverses the voltages in the cell assembly to suit nerve or mustard agent vapor which have opposite charges when ionized. An internal motor/pump assembly (sample pump) continually draws air in through the nozzle assembly. the vapor molecules are electrically charged (ionized) by a weak radioactive source in order that the vapor molecules can be detected. The current produced by this electrode is analyzed by a microprocessor which drives the display assembly. 1-8 . INTRODUCTION.TM 3-6665-343-23&P Section IV. and a change in wind direction could quickly bring a hazardous level of agent vapor to a previously safe area. The air is then passed over a heated membrane assembly before being exhausted back into the atmosphere via an exhaust vent at the side of the nozzle assembly. The CAM samples air in the immediate vicinity of the nozzle for the presence of G or H chemical agents. The closed cell assembly system air is circulated by a recirculating pump through molecular sieves which keep the system dry and chemically clean. PRINCIPLES OF OPERATION 1-16. Air sample conditions a short distance away from the CAM may be quite different. CAM determines the concentration of the nerve or mustard agent present and indicates the vapor hazard by displaying a number of bars on the display assembly. TM 3-6665-343-23&P Principles of Operation 1-9 . An analog-to-digital converter changes the varying cell analog output to digital for processing in the microprocessor.TM 3-6665-343-23&P The CAM has two operating modes. membrane. CAM monitors for mustard agents. CAM monitors for nerve agents. Heater controllers and heaters keep the temperature of the nozzle.
