Model R600 ultra-thin surface contamination monitor

Description

    The R600 Surface Contamination monitor has been awarded the AMT Innovation Design Award for its exceptional ergonomic design. Developed by COLIY Corporation, this cutting-edge instrument utilizes COLIY patented ultra-thin dual-flash detector technology. By eliminating bulky photomultiplier tubes (PMTs), it achieves a compact 16mm thickness with an effective detection area of 375px², capable of detecting both α and β radiation. The sensor's non-inflatable design significantly reduces operational costs while enhancing user-friendliness. The optional ultra-thin cesium iodide γ-ray sensor and dual-flash detector are integrated on the same plane, enabling simultaneous detection of all three radiation types. The 0.5mm-thick plastic scintillator in the dual-flash detector effectively minimizes gamma-ray interference. With an aluminum window coating thinner than 3μm that absorbs only 1MeV of α radiation, the system delivers real-time detection and independent display of α, β, and γ radiation values.

    The R600 Surface Contamination monitor delivers rapid and reliable radiation contamination screening. It directly detects α,β radioactive contamination levels and γ-rays on surfaces with high detection efficiency and fast response speed. The device fully meets users' requirements for high sensitivity, multifunctionality, and ease of operation. Designed ergonomically with a specially shaped handle for secure grip, the R600 ensures palm-free contamination exposure. Featuring a calibration factor function, users can adjust parameters independently. Its patented algorithm maintains stable background values while providing rapid response and significantly enhanced sensitivity. Anti-saturation circuits prevent over-range and electromagnetic interference, combined with safety calibration features that minimize radiation exposure to calibration personnel.

The ultra-thin surface contamination tester can be subdivided into two types:

Model R600: Measuring α and β rays, using ultra-thin dual flash sensor

Model R600PRO: Measures α, β, γ and Χ rays using ultra-thin dual flash sensor + cesium iodide sensor

COLIY ultra-thin dual flash sensor COLIY ultra-thin dual-flash sensor, developed over five years, is only 16mm thick and can be used to detect α and β rays. The sensor can be replaced as a whole, avoiding the need to buy the whole machine again.

Application

        The R600 surface contamination detector is designed for use in environmental protection, military, customs, health, nuclear industry, civil aviation, pharmaceutical, and nuclear power plant systems. It is used to monitor radiation contamination levels in environments such as markets, workplaces, laboratories, hospitals, isotope production facilities, nuclear material transportation and storage sites, and commercial inspection facilities. The device can also detect radioactive contamination on surfaces including food, work surfaces, floors, walls, hands, and clothing.
