RSI has a large variety of instruments for Environmental Monitoring. However, the corner stone of these instruments is the RS-250 Gamma Monitoring System. The RS-250 operates as a regional or local network for the continuous monitoring of released nuclear and radioactive material. The RS-250 technology offers great flexibility in deployment due to the large variety of communication and power options. The RS-250 utilizes advanced DSP / FPGA technology and software techniques that provide laboratory levels of spectral performance in harsh and extreme environments. The RS-250 NaI offers a full gamma spectrum (0 – 3 MeV) to differentiate the source of radiation and also has a very large dynamic range of 6 decades.

The RS-330 Portable Gamma-Ray Spectrometer is the new generation of lightweight field spectrometers providing the highest sensitivity as well as a wide selection of measurement methods including quantitative analysis.
