CZT spectrometric personal radiation detector
Find the source.Identify the isotope.Measure the exposure.
The GalaxRay V3 pairs a high-resolution CZT detector with on-board radionuclide identification and continuous dose-rate monitoring, in a 250 g handheld that runs on three buttons.

Why GalaxRay
Advanced technology.
Practical performance.
01
High-resolution detection
A CZT detector delivers 1.6–2.5% energy resolution at 662 keV, giving detailed gamma spectra for confident nuclide identification.
02
Several tools in one
Detect gamma radiation, identify up to five nuclides, monitor dose rate and record it all, without switching instruments. Neutron detection is optional.
03
Simple and portable
250 g, three buttons and up to 26 hours of battery life. Sophisticated analysis in a handheld anyone on the team can run.
04
From field to report
GalaxRayWiz moves stored spectra and dose-rate histories to a Windows PC over USB or Wi-Fi for review, analysis and records.
Applications
Built for the people who have to know what’s there.
Government agencies
We provide protection and safety for the people who protect everyone else. Emergency services rely on the GalaxRay V3 because it is durable, informative and easy to use, with visual, audible and vibration alarms the moment dose rate passes a set threshold. One unit locates a source, identifies the nuclide and records dose rate and cumulative dose, helping agencies monitor the homeland for radiation threats and the illicit trafficking of nuclear materials.
First Responders

Hospital radiation safety
Radiation is part of everyday hospital care, from X-ray and CT to nuclear medicine, PET imaging and radiation therapy. The GalaxRay V3 gives radiation safety officers, nuclear medicine technologists and facilities staff one handheld instrument to:
- Check incoming radioactive packages and deliveries
- Survey rooms, hot labs and treatment areas after procedures
- Find misplaced sources and catch contaminated waste before it leaves the building
- Screen patients and staff arriving from a radiological incident
- Keep dose-rate records for compliance and audits
In specialty centers that work with isotopes such as Tc-99m and I-131, on-the-spot identification tells staff exactly what they are dealing with.

Benefits of Our Products
Knowing what’s there, and how much, makes every place safer.
Safer workplaces
Workers see their dose rate in real time and get an alarm before exposure becomes a problem. Every shift is recorded, so supervisors can show that limits were respected.
Safer communities and homes
Find orphan sources, contaminated scrap and illicit material before they reach a neighborhood, and give residents near nuclear facilities monitoring they can trust.
Safer ports and borders
Screen cargo, containers and commercial vehicles at ports, border crossings and weigh stations, and identify what set off an alarm on the spot.
Fewer false alarms, faster decisions
Isotope identification tells a recently treated medical patient or naturally radioactive goods apart from a real threat, so operations keep moving and real threats get the right response.
Records you can stand behind
Spectra and dose histories download to GalaxRayWiz for audits, incident reports and regulatory compliance.
One device, four configurations.

GalaxRayWiz software
Every reading, ready to review.
Every GalaxRay ships with GalaxRayWiz for Windows. Connect over USB or Wi-Fi, upload stored spectra and dose-rate profiles, and review identified nuclides, energy peaks and exposure over time on a full-size screen.
