Product Overview

The RC4000 (RC4000-T) is designed to screen α/β surface contamination on the hands, feet, and clothing of personnel exiting radioactive controlled areas. Integrating large-area dual-scintillator detectors, the unit ensures rapid and reliable monitoring. Multiple position sensors standardize personnel stance, while a 10-inch touchscreen and voice prompts guide users and display results in real time.

The system integrates a centralized personnel information management system​ built on a relational database architecture, creating a strong link between measurement records and personal identity. It supports dual-mode identification: manual lookup via the touchscreen or automatic IC/ID card recognition (with an optional external card reader). This person-data binding functionality fully complies with the IAEA GSG-7​ guidance regarding the traceability of individual radiation monitoring records.

 

Applications

Equipped with a reserved DO interlock interface, the monitor can be linked with turnstiles and barrier gates. It is primarily deployed at access points of nuclear power plants, radiopharmaceutical facilities, radioactive laboratories, nuclear fuel production sites, and radioactive waste treatment facilities.

 

Features

  • Low Maintenance:​ Requires no process gas; modular design simplifies servicing and reduces operating costs.
  • Selectable α/β Measurement Modes:​ Automatic α/β discrimination enables simultaneous α+β measurement, as well as α‑only​ and β‑only​ readouts when selected.
  • Auto Background Subtraction:​ Automatically updates and deducts background in real time.
  • Intuitive Operation:​ Voice guidance for procedure and alerts specifying contamination type and location. A 10-inch touchscreen provides graphical visualization of results.
  • Remote Data Management:​ Supports customizable remote data transmission and centralized data management.
  • Easy Decontamination:​ Polished stainless steel detector surfaces resist contamination and facilitate quick cleaning.
  • Mobile & Foldable Design:​ Bottom-mounted casters allow easy relocation; foldable structure simplifies transportation and on-site installation.
  • Bilingual Interface:​ One-click switching between Chinese and English GUI.
