Title: A data management system for radiological data

A data management system oriented toward the visualization of large data sets has been developed. The system, which runs under the Windows{trademark} operating environment, provides most of the image-based algorithms developed by NASA for space-based imaging. When used in conjunction with large data sets, such as those acquired using position-sensing proportional counter based survey methods, the system can show images of survey data and subject those images to numerous mathematical transformations. The application of such mathematical treatments allows radiological survey data to be analyzed to an unprecedented extent. Visualization of survey data permits a user to see minor artifacts that would have been missed using only conventional survey techniques. The imaged survey data can be subjected to many different treatments, such as filters, smoothing, thresholding, color mapping, and statistical analyses. A variety of radioactive objects and areas have been surveyed using this system in conjunction with a novel floor monitor described elsewhere. Collection and examination of data in this fashion poses a new paradigm for assessing surface contamination. This research demonstrated that new methods for assessing survey performance are needed.
