Navy gearing up to replace
shipboard radiation detection
equipment that measures
gamma rays
May 28, 2015
WEST BETHESDA, Md., 28 May 2015. U.S. Navy shipboard
electronics experts are planning an industry competition to replace
the AN/PDR-65 gamma radiation detectionsystem.
Officials of the Naval Surface Warfare Center Carderock Division
in West Potomac, Md., notified industry this week of an upcoming
solicitation to provide a high-level conceptual design, computerized
drawings, and a physical model of a potential replacement for the
Navy AN/PDR-65 radioactivity, detection, indication, and computation
(RADIAC) system.
AN/PDR-65 is designed to detect and measure gamma radiation
emitted by high-altitude nuclear explosions. Gamma rays are
high-energy electromagnetic ionizing radiation that can cause
serious or lethal radiation sickness if not detected and shielded
against quickly.
Gamma radiation can penetrate the human body easily, and
can cause whole-body acute radiation syndrome even before
radiation effects are evident on skin.
The AN/PDR-65 RADIAC system has two primary elements:
the detector unit and RADIAC meter. The detector unit is
located at the top of the ship's mast to detect an enveloping
radiation cloud and nuclear fallout.
The RADIAC meter is installed on the ship's bridge, and displays
gamma ray dose rate and accumulated dose. The primary meter
displays the dose rate. Each time the system detects a dose
of 1 rad it sounds a loud beep.
Navy officials say they plan to issue a request for proposals
on 10 June 2015. Email questions or concerns to the Navy's
Ashley Fortson at ashley.fortson@navy.mil.
