NE Technologies DP6DD — Large-Area Alpha/Beta/Gamma Dual Phosphor Scintillation Probe

NE Technologies DP6DD — Large-Area Alpha/Beta/Gamma Dual Phosphor Scintillation Probe

The NE Technologies DP6DD is the original production variant of the industry-standard DP6 series large-area dual phosphor scintillation probe, designed and manufactured by NE Technologies Ltd. (UK) before the line was acquired by Thermo Electron Corporation. This is the probe that established the DP6 as a workhorse of health physics programs in nuclear power, research, and radiological laboratory environments worldwide.

The "DD" designation identifies the extra-reinforced window frame variant — built for demanding field conditions where probe durability and window protection are critical. The 100 cm² active detection area enables fast, efficient contamination surveys of personnel, tools, equipment, and work surfaces.

Key Features:

• Dual phosphor (ZnS/BC400) scintillation detector for simultaneous alpha and beta/gamma discrimination
• Extra-reinforced window frame — the defining feature of the DD variant
• Large 100 cm² rectangular thin window for high-efficiency 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

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: ~40 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. Collectors and HP professionals often seek the NE Technologies branded units as the original source manufacturer.
