NE Technologies DP6BD — Large-Area Alpha/Beta/Gamma Dual Phosphor Scintillation Probe

NE Technologies DP6BD — Large-Area Alpha/Beta/Gamma Dual Phosphor Scintillation Probe

The NE Technologies DP6BD is the standard MHV-connector variant of the industry-proven DP6 series large-area dual phosphor scintillation probe, designed and manufactured by NE Technologies Ltd. (UK) before the product line was acquired by Thermo Electron Corporation. The DP6 series established itself as a workhorse of health physics programs in nuclear power, research, and radiological laboratory environments worldwide.

The DP6BD features a 100 cm² rectangular detection window with standard window frame and protective grille, offering excellent sensitivity and reliability for routine contamination surveys of personnel, tools, equipment, and work surfaces.

How the BD Differs from the DD: The DP6BD uses a standard window frame, while the DP6DD features an extra-reinforced window frame for added durability in harsh field environments. Both probes share identical detection efficiencies and are otherwise functionally equivalent.

Key Features:

• Dual phosphor (ZnS/BC400) scintillation detector for simultaneous alpha and beta/gamma discrimination
• Large 100 cm² rectangular window for fast, efficient surface surveys
• Protective grille with 80% transmission — shields window while preserving sensitivity
• MHV connector — compatible with a wide range of survey meters
• Field-replaceable detector window
• Lightweight and ergonomic for extended survey operations

Specifications:

• Detector Type: Alpha-Beta-Gamma Dual Phosphor Scintillation (ZnS/BC400)
• Active Window Area: 100 cm² (rectangular)
• Connector: MHV
• Grille Transmission: 80%
• Background Response: <10 cps (beta) / <0.1 cps (alpha)
• Gamma Response: ~50 cps at 1 µSv/h (Cs-137)

Detection Efficiencies:

Compatible Survey Meters: NE Electra, NE Delta, and Thermo Electron/Thermo Scientific compatible ratemeters including the ASP-2, E-600, and RM-25. Can replace a GM probe without requiring ratemeter replacement.

Recommended Applications:

• Personnel frisking and contamination monitoring
• Tool, equipment, and work area surveys
• Nuclear power plant health physics programs
• Radiological laboratory contamination control

Brand Note: This unit was manufactured under the original NE Technologies brand — the designer of the DP6 series — prior to acquisition by Thermo Electron Corporation. It is functionally identical to units later sold under the Thermo Electron and Thermo Scientific labels and is fully cross-compatible with those instruments.
