RadSearch is a device for measuring and quantifying radiation in the environment. It is particularly applicable to decommissioning and nuclear cleanup activities. RadSearch is capable of searching for, locating and quantifying radioactivity distributed on surfaces, within equipment and in pipe work and determining radiation dose in the environment. It consists of a detection head with a combined lanthanum bromide (LaBr3) scintillation detector and photomultiplier, video camera and distance measuring laser range-finder system.
