Protect employees with electronic personal dosimeters (EPDs), which provide real-time radiation monitoring in critical areas of the facility.
Compared to earlier EPD models, the Thermo Scientific™ EPD TruDose Electronic Personal Dosimeter offers improved accuracy, increased functionality, and simpler operation while efficiently monitoring gamma, beta and neutron radiation (depending on the model chosen) in settings needing radiation exposure oversight.

Product Overview
Uncompromised Radiological Performance
- At lower dosage rates, unprecedented sensitivity as low as 0.05 μSv/hr (0.005 mrem/hr) ensures exposure precision
- IP65 (EPD TruDose BG) and IP67 (EPD TruDose NG & G) offer better defense against water and dust
- Tolerance to electromagnetic fields is improved with integrated electromagnetic shielding
- Gamma, beta, and neutron rays are measured using multi-detector technology
- Uncompromised radiological performance
- Enhanced sensing of medical and industrial pulsed fields
- Enhanced range of dose rates
Increased User Efficiency
- By establishing warning thresholds, users can react before an alarm circumstance occurs
- Faster IrDA data transfer speeds provide increased throughput at checkpoints
- The real-time clock facilitates event documentation and troubleshooting
Simplified User Experience
- Easy to read graphical display
- Proactive, redundant, and configurable messaging
- Simple menu structure
