RS-500 AIRBORNE GAMMA RAY SPECTROMETER

The RS-500 is the world’s most advanced AIRBORNE gamma-ray spectrometer system utilizing state-of-the-art DSP/FPGA technology for previously unachievable levels of spectral data performance. RSI has added very advanced technologies to the RS-500 systems to make it at the very leading-edge of this type of equipment and making obsolete all current available technologies by a significant factor. Yet it is designed to be easy to interface and virtually foolproof to use making the RS-500 system the clear technological leader in this sophisticated field.
