NUCLEAR-BIOLOGICAL-CHEMICAL (NBC) DEFENSE SYSTEMS
A wide range of items and systems provide today's warfighter with contamination avoidance, protection, decontamination and obscuration capabilities. Several representative examples are provided below.
The United States has fielded several types of nuclear detection and monitoring systems to assist in contamination avoidance. A family of radioactivity detection indication and computation (Radiac) equipment is being fielded to U.S. forces to upgrade 30-year-old technology with digital equipment that incorporates advances in modern electronics.
Radiac provides soldiers and commanders with nuclear radiation detection equipment, allowing them to fight effectively and survive on the nuclear battlefield. It also minimizes nuclear radiation exposure of troops during such peacetime missions as peacekeeping, nuclear-accident response and recovery of vehicles and equipment containing radioactive material.
The AN/UDR-13 Radiac Set is a compact, handheld, pocket-size tactical radiation meter. It measures and displays gamma dose rate and total gamma/neutron cumulative dose in a battlefield environment.
A push-button pad enables mode selection, functional control and the setting of audio and visual alarm thresholds for both dose rate and mission dose. A "sleep" mode with automatic wake-up enhances battery life. A liquid crystal display provides data readout and warning-mode messages. As a replacement for the older IM-93/PP-1578, UDR-13 improvements include prompt dose measurement, including neutrons, alarms and measures rate, backlit display, and stable readings and calibration. It does not need a separate charger.
The AN/VDR-2 Radiac Set detects and measures nuclear radiation from fallout and radioisotopes. The system replaces the older IM-174 and AN/PDR-27. It performs ground radiological surveys from vehicles or, in the dismounted mode, as a handheld instrument. …
