Laser-Assisted Ranging and Data System (LARADS)
LARADS is a radiological surveying instrument that automates the collection of indoor radiation measurement data or data for outdoor locations where a global positioning system (GPS) is not available. The system consists of an auto-tracking total station with a laser-range finder capable of automatically tracking radiation detectors. Position and radiation data are recorded every one second, producing a virtual data presentation. This system is coupled with conventional radiation detectors for indoor surveys or surveys where higher positional accuracy is desired (less than two cm). LARADS yields data in accordance with Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) guidance, making it an ideal tool for pre- and post-remediation survey requirements.

The LARADS has been used to characterize contamination and verify decontamination at DOE sites including the DOE Hanford site and the Rocky Flats Environmental Technology Site.
