HDS-101G/GN

Detection and Identication - Risks Prevention

HDS-101G/GN

Handheld Search and Isotope Identication
Device

HDS-101G/GN are handheld devices designed to

search for and identify radioactive materials and to

respond to radiological threats such as illicit trafc-

king and RDDs.

They are able to identify radionuclides and classify

them as medical, industrial, naturally occuring radio-

active materials (NORM) and special nuclear

materials (SNM).

They can be used to detect, localize and characterize

threats during radiological surveys or for secondary

screening as perfect complement for installed radia-

tion detection portals.

FEATURES

● Gamma & neutron independent measuring channels

● Wide gamma measurement range

● Very high sensitivity and fast response

● Detection threshold relative to background level and

dose rate safety alarm

● Real time rejection of sudden background variation

(VBS algorithm)

● Automated spectra acquisition on alert and automatic

identication (NMD algorithm)

● Clear discrimination of risk categories

● LCD display with backlight

● Spectrum display

● Visual and audible alarms

● Wireless communication interface

● Designed to meet/exceed IAEA, IEC, ANSI standards

The HDS-101G/GN are ideally suited for First

Responders, Border & Customs inspectors, Law En-

forcement Ofcers, Site Security in critical infrastruc-

tures, and for all applications related to the control of

radioactive and nuclear materials.
