RoScan (Obsolete)

Device type: Gamma scanner

The RoScan Gamma scanner was jointly developed by the Verein für Kernverfahrenstechnik und Analytic Rossendorf e.V. (VKTA / Nuclear Engineering and Analytics Rossendorf Inc.) and GBS Elektronik GmbH to measure radio-contaminated rooms or objects. With the RoScan it is also possible to locate radioactive leaks in tanks and pipelines. The RoScan takes a picture with a digital camera and measures single gamma spectra with a collimated detector. The radiation intensity is superimposed and visualized as color information on the recorded image.

Hardware

The RoScan Gamma Scanner consists of two units, the measuring head and a portable control unit. Both components can be connected to each other by a cable up to 100m long.
The power supply for the entire system is from the 230 V mains. Thus, only a single hermetically sealed cable, which is easy to clean, is connected to the measuring head.

The measuring head consists of a solid housing, which contains the mechanical drive, a camera, the collimated detector, an MCA-527, a laser pointer as well as the control electronics.
The camera operates with a resolution of 640 × 480 pixels. A SC2525 (CsI) or a CZT500 (CdZnTe) module is used as detector. Depending on the required spatial resolution or sensitivity, other detectors can also be used. Therefore only the collimator has to be adapted to the detector geometry. The integrated laser pointer is very useful when finding contaminated sites.

The control unit incorporates a laptop for controlling the measuring head, the power supply for the laptop and measuring head, as well as a communication unit. By integrating all these components into one package, only two cables - the power supply cable (230 V ~) and the control cable for the measuring head – must be connected externally. The installation of the laptop can be carried out with almost any model with USB connection without problems.

Software

All functions of the measuring head, including the integrated MCA-527 as well as the camera, can be controlled with the program RoScan. The program also gives the user numerous possibilities for evaluation and automation options. For example, reports can be generated and saved. Furthermore, the evaluation programs Identify and MCAPrint for the MCA-527 can be used for the evaluation and preparation of the measurement data. With RoScan, you can click on any pixel in the camera window by mouse and the corresponding spectrum is displayed in the main window.
