Counting and other Detection Technologies.

Highly sensitive scintillation methods reveal the presence of contaminants far below regulatory requirements for all sort of isotopes. Alpha discrimination capability is especially valuable in cases where actinides are the issue.

All familiar types of counting systems from liquid scintillation systems, solid state detectors (scintillation based and otherwise) to gas based proportional devices. In ADDITION, a valuable part of our quantification and characterization suite is an ICP source mass spectrometer with TIMS and SIMS options.

Electronic design and modification capabilities with pulse processing and counting a specialty We have a fully modern and equipped electronic design shop.. Experience in both CAMAC and NIMBIN engineering for :

  •   nuclear systems measurements
  •   nuclear experiments
  •   high energy physics data collection systems.

Among other resources, we have at our disposal for immediate application to detection and protection problems, conventional or novel:

We are ready to sample almost any matrix for for low level activity using a variety of in-field methods and lab work-up to get an optimal reading on any isotope of interest.

Our expertise across all areas of nuclear physics and nuclear radiations measurements allows us to also help specify project where use and management of third party resources is required in the scope of large projects.

Our analysis capability extends to many site types, suspected sample forms and types,  and at remarkable sensitivities.
