TYPES OF HANDHELD INSTRUMENTS
There are several types of handheld radiation
detection instruments that can be considered,
including:
• Personal Survey Meter/Personal Radia-
tion Detector (PSM/PRD) – The most widely
deployed type of radiation detector, PRDs are
belt-worn devices that form the frontline for
threat interdiction, offering first responders, or
security personnel, the knowledge they need
of their surroundings to ensure their personal
protection. However, they require the support
of more capable instruments once the initial
detection has been made. Additional tools are
needed to perform identification once the ini-
tial detection has been made.
• Spectroscopic Personal Radiation Detector
(SPRD) – can be belt-worn or vehicle-mount-
ed to function as a PRD. Additionally, they pro-
vide real-time spectroscopic capability for
monitoring gamma and/
or neutron activity, per-
forming isotope identifi-
cation, enhancing on-scene
information, and safer de-
cision-making

during a radiological event.
• Radionuclide Identifica-
tion Device (RID) – hand-
held devices that are most
often used on the front line

tion on-scene. RIDs are generally more sen-
sitive than PSM/PRDs and SPRDs due to their
use of crystalline scintillation or semiconduc-
tor detector materials. They are considered
the best all-purpose survey tool for gamma
and/or neutron radiation, and they generate
the spectroscopic info needed to identify
specific nuclides.

tem for responders, and a 2017 ‘ASTORS’ Homeland Security Award Winner.)
