WINTACT WT3130 Nuclear Radiation Detector
The WINTACT WT3130 is also a Geiger counter-based portable radiation detector.
According to the WT3130 product information, its real-time measuring range is:
010,000 μSv/h (10 mSv/h)
Its cumulative measurement range is:
0500,000 μSv (500 mSv)
The specified energy range is:
48 keV1.5 MeV
Its stated sensitivity is:
80 CPM/μSv (Co-60)
The WT3130 also provides real-time data tracking and cumulative dose monitoring.
WT3130 Real-Time Data Tracking
One of the notable features of WT3130 is its graphical real-time measurement display.
Instead of relying only on a single numerical reading, users can observe how the detected radiation level changes during monitoring.
This can be useful when comparing:
Different rooms
Industrial areas
Material samples
Laboratory locations
Equipment areas
Backgrond reference points
The WT3130 also provides an average measurement display.
GC-02 for Marble and Ore Inspection
One of the clearest application differences is the GC-02's positioning for Marble & Ore Inspection.
Customers involved in:
Marble
Granite
Natural stone
Minerals
Ore
may want to perform preliminary radiation screening around these materials.
GC-02 is specifically marketed for this type of application.
However, a Geiger counter measures supported ionizing radiation. It does not automatically identify the radioactive substance inside a stone or mineral sample.
GC-02 for Metal Radiation Screening
The GC-02 product information also lists Food & Metal Detection.
For industrial customers, the metal application can be relevant to:
Metal materials
Scrap metal
Used industrial equipment
Imported materials
Recycling applications
In this context, “metal detection” refers to radiation screening involving metal materials.
GC-02 is not a conventional metal detector used to locate ordinary metal.
WT3130 for Industrial Monitoring
The supplied WT3130 product information identifies application environments including:
Airports
Customs
Docks
Security organizations
Nuclear power plants
Research institutions
Laboratories
Workplaces where personnel may potentially encounter nuclear radiation
This gives WT3130 a particularly strong positioning for industrial, institutional and technical radiation monitoring.
GC-02 for Nuclear Industry Applications
The MTM GC-02 product information specifically lists Nuclear Industry among its applications.
This makes the GC-02 relevant to customers searching for portable radiation monitoring equipment associated with nuclear-related environments.
However, professional nuclear facilities can require specialized radiation instruments depending on the measurement objective.
A handheld Geiger counter should not automatically be treated as a replacement for every professional radiation safety system.
GC-02 for Radioactive Medical Equipment
Another application listed for GC-02 is:
Radioactive Medical Equipment
This makes it worth considering for appropriate general radiation monitoring applications involving relevant technical or medical environments.
Formal medical radiation surveys or equipment compliance testing may require specialized calibrated instrumentation and defined procedures.
The instrument should always be selected according to the actual application.
Which Model Is Better for Cumulative Dose Monitoring?
WT3130 has clearly documented cumulative-dose functionality in the supplied product information.
Its cumulative measurement range is:
0500,000 μSv (500 mSv)
The starting time of the current dose accumulation can also be viewed.
The product information specifies a maximum accumulation duration of:
9,999 hours
For customers specifically interested in observing accumulated dose over time, this is an important WT3130 feature.
Which Model Is Better for Graphical Monitoring?
The WT3130 product information specifically highlights:
Real-time data tracking
The display can show changing measurement information graphically.
An average measurement value can also be displayed.
This may be useful for technicians who want to observe radiation trends while surveying different locations.
Radiation Alarm Comparison
WT3130 provides a dual alarm system using:
Sound indication
Visual indication
The alarm switch and alarm value can be configured.
GC-02 also provides alarm-related radiation monitoring functions according to its product design.
When selecting a detector, customers should consider whether the available alarm method suits the working environment.
Which Is Better for Laboratories?
The WT3130 product information specifically identifies laboratories and research institutions as application environments.
Its combination of:
Real-time measurement
Graphical data tracking
Average measurement
Cumulative dose monitoring
Adjustable alarm
may be attractive for laboratory users requiring portable monitoring.
GC-02 can also be considered where its radiation detection specifications meet the application's requirements.
Which Is Better for Stone Suppliers?
For customers specifically involved with:
Marble
Granite
Ore
Minerals
Natural stone
GC-02 has particularly relevant product positioning because Marble & Ore Inspection is explicitly listed among its applications.

Which Is Better for Scrap Metal?
GC-02 again has relevant application positioning because metal radiation screening is specifically mentioned.
WT3130 can also detect supported X-ray, beta and gamma radiation and can therefore be considered for appropriate preliminary radiation monitoring.
For large recycling facilities, however, a portable Geiger counter may not replace fixed portal monitoring or other specialized radiation detection systems.
Can Either Detector Identify a Radioactive Isotope?
Radiation detection and radionuclide identification are different functions.
The supplied WT3130 information does not state radionuclide identification capability.
Likewise, a standard Geiger counter reading should not automatically be interpreted as identification of a specific isotope.
If the application requires determining exactly which radionuclide is present, specialized analytical equipment may be required.
Can GC-02 or WT3130 Test Seafood or Water?
A portable Geiger counter can detect supported ionizing radiation reaching its detector.
However, this does not automatically determine:
Which radionuclide is present
Its concentration in seafood
Its concentration in drinking water
Its concentration in seawater
Whether the sample meets a regulatory limit
Therefore, GC-02 and WT3130 should not be promoted as automatic food or water safety certification instruments.
They are more appropriately positioned for radiation monitoring and preliminary screening.
GC-02 vs WT3130: Which Should You Choose?
Consider the FNIRSI GC-02 if your application is particularly related to the product's listed areas such as:
Metal radiation screening
Marble and ore inspection
Nuclear industry environments
Radioactive medical equipment
Consider the WINTACT WT3130 if you particularly value:
Real-time radiation measurement
Graphical data tracking
Average measurement display
Cumulative dose monitoring
Adjustable sound and visual alarms
Laboratory and research application positioning
Neither instrument is automatically the best choice for every user.
The correct detector depends on the actual monitoring requirement.
