RADIAC

LI 2920 - RADIAC is the Navy's budget line item dedicated to the procurement and support of Radiation Detection, Indication, and Computation (RADIAC) equipment. The primary goal of this program is to ensure the Navy, Coast Guard, and Military Sealift Command vessels, as well as all Navy shore installations, have modern, reliable radiation monitoring instruments. These instruments are critical for maintaining compliance with federal regulations, safeguarding personnel, supporting continuity of operations during radiological or nuclear events, and protecting the environment from radioactive contamination.

M2100 - Survey Meters encompasses the procurement of radiation survey meters and the Radiological Detection System (RDS). These devices are essential for detecting, measuring, and monitoring radiation levels in operational contexts involving radioactive materials, including nuclear reactor operations, maintenance, X-ray testing, research, and medical diagnostics. The RDS is being developed as a joint instrument for use across the Army, Navy, Marine Corps, Air Force, and select NATO allies, promoting interoperability and surge support in theater operations. The RDS will replace the aging IM-265/PDQ Multi-Function RADIAC Control Unit and provide enhanced capability to survey for Alpha, Beta, Gamma, and Neutron radiation.

M2200 - Dosimetry focuses on the acquisition of dosimeters and supporting systems to monitor individual radiation exposure. This includes DT-702 cards and holders, extremity dosimeters for concentrated exposure such as hands during glove box operations, accident dosimeters for fast neutron detection near reactor compartments, and battlefield dosimeters for high-energy gamma and neutron irradiation during nuclear or radiological events. The Navy Occupational Dosimeter System (NODS) is a major upgrade, consolidating legacy records and improving the ability to detect, transmit, record, and report radiation doses. These efforts enhance personnel safety and regulatory compliance.

M2400 - Other RADIAC provides for the replenishment and supplementation of stocks of specialized RADIAC instruments that do not fit into the main functional groupings. This ensures that emergent requirements and inventory losses can be addressed promptly, maintaining operational readiness across the fleet and shore installations. The program supports a wide range of instruments and dosimeters, reflecting the broad scope and critical nature of radiological monitoring in Navy operations.

M2500 - Air Sampling Systems includes the procurement and maintenance of systems for monitoring airborne radioactivity, such as Air Particle Detectors (APD) for ships and submarines. These systems are vital for detecting leaks from nuclear reactors and ensuring that radioactivity is not inadvertently released into the environment. The APD Ship program involves upgrading and converting existing units to newer models, which offer improved reliability, reduced false alarms, and lower maintenance requirements. Research is also ongoing to replace obsolete portable air samplers, with the Naval Surface Warfare Center Carderock Division leading testing efforts.

M2600 - Laboratory Test Equipment supports the acquisition and installation of calibrators and irradiators used to calibrate all Navy radiological detection equipment. These calibrators are essential for ensuring that RADIAC instruments meet American National Standards Institute (ANSI) requirements and operate safely. The program also includes procurement of initial spare parts, installation, and training at Navy RADIAC Calibration Laboratories, as well as specialized calibrators for battlefield dosimeters to support high-throughput calibration and reduce total ownership costs.

M2830 - Support - Production Engineering funds the labor costs for government and contractor personnel involved in preparing acquisitions, including engineers, health physicists, scientists, and other subject matter experts. This support is crucial for managing the acquisition lifecycle, ensuring technical standards are met, and maintaining the operational effectiveness of the RADIAC program. Contract service fees through the Navy Working Capital Fund are also included, reflecting the administrative costs associated with hardware and service contracts.
