RC2000 Whole-body αβ contamination monitor

Product Overview

The RC2000 Whole-Body Alpha-Beta Contamination Monitor is designed for use in nuclear facilities, hospital nuclear medicine departments, nuclear medicine plants, radiological laboratories, and other locations exposed to radioactive contamination. It monitors all body parts (including hands, feet, and head) of personnel leaving controlled areas for radioactive contamination. When contamination exceeds permitted levels, the monitor issues an indication and alarm signal and prohibits the opening of exit gates, thereby preventing the contamination source from leaving the controlled area. This device is a crucial line of defense in controlling the spread of radioactive contamination and ensuring the safety of personnel and the environment.

 

The device can operate independently to provide contamination detection and alarms, or it can be seamlessly integrated into a personal dose management system or radiation safety monitoring network, enabling integrated intelligent control of personnel access, contamination data recording, and dose management.

Features

① Intelligent prevention and control of pollution exceeding the standard: When the pollution index on the surface of the tested person exceeds the standard, the equipment will immediately trigger the sound and light alarm and automatically start the channel interception. A three-pronged prevention and control mechanism of "physical blocking" precisely prevents people from entering contaminated areas.

② Two-step measurement: A two-step method provides rapid, full-coverage measurement of the person being measured, accurately locating the contaminated area.

③ Liftable head detector: The head detector can be raised and lowered to flexibly accommodate people of different heights.

④ Facial recognition and registration measurement: An integrated facial recognition system verifies identity and registers personal information, eliminating the need for fingerprint touch or card swiping, reducing cross-contamination. Measurement results are linked to personal information, creating a "one-person, one-file" database for full traceability.

⑤ Intelligent voice prompts: Intelligent voice guidance provides seat reservation and measurement prompts, eliminating the need for dedicated operator input.

⑥ High-definition touchscreen: A 10-inch high-definition color LCD touchscreen with high sensitivity and multi-touch displays real-time measurement data.

⑦ Built-in light-controlled sensor light: Intelligent sensing automatically illuminates dark environments, providing a bright measurement environment and ensuring worker safety.

⑧ Two operating modes: Normal and emergency modes to meet diverse application scenarios.
