Radiation detection equipment which can control the distance between two image acquisition modules and the method which can control the maximum error rate in distance detection to the radiation source

摘要

PURPOSE: A radiation source with a variable gap between image taking modules and a method of maintaining the distance error of the radiation source using the same are provided to map 3D radiation information in real time and measure a radiation source with a constant error range by a defined distance. CONSTITUTION: A radiation source with a variable gap between image taking modules comprises image taking modules(1,1') and a gap adjusting unit(2). The image taking modules are loaded on a mobile robot. The number of the image taking modules is two. The gap adjusting unit varies the gap between the image taking modules. A radiation source detecting unit varies and measures the radiation source so that when calculating the distance to the radiation source, the gap between the image taking modules maintain a distance error range set by a defined distance. The gap adjusting unit comprises a plate, a gear groove, a module supporting plate(23), a module moving motor(24), and a gear.
