TSA Systems has been in the business of designing and manufacturing SNM (Special Nuclear Materials) radiation portal monitors since 1981. TSA Systems, Ltd. was formed in 1987 with the merger of TSA Systems, Inc., founded in 1975, and Geoscience Associates, Inc., founded in 1961. The company has a distinguished history of providing high quality products and service.
The product line for TSA Systems is anchored by radiation portal monitors (RPM) for pedestrians, vehicles, and trains. Hand held radiation monitors and analyzers are also produced as are box and barrel monitors for radioactive waste measurement. Additional custom systems are designed and manufactured for specific needs and requirements.
In 1983 TSA Systems pioneered a new generation of all digital radiation portal monitors in close conjunction with the Advanced Nuclear Technology Group at Los Alamos National Laboratory. The first of these was installed at the Rocky Flats Plant in Colorado in 1983-84. Since then, TSA’s innovative approach to problem solving has led to more modern generations of pedestrian, vehicle and train radiation portal monitors and detection systems.
TSA has manufactured and installed more than 400 pedestrian radiation portal monitors and 175 vehicle radiation portal monitors. These systems are installed in many countries throughout the world. In fact, TSA Systems has provided such extensive portal radiation monitor coverage internationally, that the sun never sets on the global presence of TSA's radiation monitors!
The majority of TSA’s installed radiation portal monitoring systems are gamma only, yet TSA has manufactured and strategically placed numerous gamma/neutron and neutron only systems as well.
Over the years, TSA has participated in many testing and evaluation programs. Some of these are well known such as RADTRAP conducted by US Customs, and ITRAP conducted under the auspices of the IAEA. TSA has also participated in numerous less formal tests and has submitted new designs to Los Alamos for testing and evaluation.
Since 1988, TSA has been actively involved with ASTM International (formerly American Society for Testing and Materials) C26.12 subcommittee on Nuclear Safeguards. The function of this committee is to initiate and maintain standards for pedestrian, vehicle, train and hand held radiation monitors, particularly those used in SNM monitoring applications.
