Three Dimensional Indoor Survey System

摘要

A new surface contamination monitor has been developed that automatically records scanning count rates orrnfixed-point integrated counts along with the associated x, y, and z coordinates. The data are logged by a hand held or laptoprncomputer and then downloaded into ArcView GIS, AutoCAD, or other commercially available computer applications wherernthe data can be processed and displayed. Single detector units with components placed in afannypack are used in difficult tornaccess areas or to perform long-term integrated measurements. A wall scanning unit consists of a computer controlled liftrnthat moves an array of up to eight detectors up and down a vertical wall surface at a defined speed. Thirdly, a floor scannerrnmoves the detector array over floors at a constant speed. Labor savings of more than 50 and 90 percent are evident whenrnusing the single unit and multiple units, respectively, when compared to conventional manual surveys.
