RADIATION DETECTOR The VideoRay Radiation Detector mounts easily using the four screws supplied, plugs into the ROV’s rear accessories connector, and its output is accessible from the control console’s serial port. A PC is required to read, plot, and alarm upon detected radiation. All required software is supplied with the system. This unit is very sensitive to gamma radiation and high energy X-Rays. The sensor is not designed to detect Alpha and Beta particles since the tube is mounted inside a pressure housing.
