Radioactive Surface Contamination Detection System

Detect Radioactive Contamination Before It Spreads

Advanced surface contamination monitoring for nuclear facilities, laboratories, decontamination operations, and radiation safety programs.

Radiation Is Dangerous. Contamination Is Transferable.
Identify radioactive contamination on surfaces, tools, equipment, and work areas in real time.

Radiation Contamination Can Spread Invisibly

Radioactive contamination is different from radiation exposure.

Contamination occurs when radioactive material is deposited on:

Surfaces

Equipment

Clothing

Tools

Work areas

If not detected early, contamination can spread through personnel movement and operational activities.

The Solution: Real-Time Surface Contamination Monitoring

Our contamination monitoring systems help radiation safety teams:

Detect contaminated surfaces

Identify radioactive spread

Verify decontamination effectiveness

Improve operational safety

 From invisible contamination → controlled environments

FAQ

Q1: What is a surface contamination monitor used for?

It is used to detect radioactive contamination deposited on surfaces, equipment, tools, and work areas.

Q2: How is contamination different from radiation?

Radiation is energy emitted from a source, while contamination refers to radioactive material physically present on surfaces or objects.

Q3: Why is contamination monitoring important?

Undetected contamination can spread through personnel movement and operational activities, increasing safety risks.

Q4: What environments is it suitable for?

Nuclear facilities, laboratories, medical isotope departments, decommissioning projects, and emergency response operations.

Q5: Can it detect removable contamination?

Yes. Surface contamination monitoring supports identification of radioactive material on surfaces and equipment.

Q6: Is it portable for field use?

Yes. It is designed for handheld and portable deployment.

Q7: Can it support decontamination operations?

Yes. It helps verify cleaning effectiveness and contamination removal.
