Radiation Monitoring

ISTI’s roots lie firmly embedded in the world of remote instrumentation control and data acquisition. For many of our clients, we create custom solutions that acquire data from remote sensors, control/view user interfaces (local and remote), and ensure the integrity of the data transmitted during the acquisition process.

Our sampling and measurement experience includes the following:

• Software for the command and control of airborne particulate matter sampling and measurement systems. We created a solution for one client to operate sampling and measurement systems for the detection of radioactive isotopes.  This software acquires spectral and state-of-health data and reports the data to a central server for further analysis. Data delivery involves the signing of the raw data using cryptographic tokens. Upon receipt, the data’s signature is verified to ensure integrity, and the data is delivered to the client’s data processing system.

• Source Term Analysis of Xenon (STAX). Under contract to the Pacific Northwest National Lab (PNNL.GOV), ISTI is developing the STAX data processing software to monitor radioactive isotope releases from industrial medical isotope production (MIP) facilities.

  The use of radiation and radioisotopes in the field of medicine has proven invaluable in the treatment and diagnosis of many diseases; however, the release of radioactive Xenon from Medical Isotope Production facilities (MIPs) presents a challenge to the interpretation of data from the Comprehensive Nuclear-Test-Ban Treaty Organization’s (CTBTO) noble gas monitoring network.

  The STAX project uses high-resolution stack detector systems to measure releases of volatile radioisotopes. ISTI supplies the software infrastructure for STAX, from gathering data at the MIPs to ensuring the secure transport of encrypted data to a centralized data repository to data storage, visualization, and automated analysis and distribution.

• Atmospheric Transport Modelling (ATM). Based on ATM, the analysis of atmospheric radiation movement, ISTI is currently developing software to calculate the emissions impact from a radionuclide source on the radionuclide concentrations detected at receptor sites.
