Training Seminar

Advanced ISOCS™ Geometry Considerations — NEW

Instructor: Cathey Sharp

Date: Tuesday, July 30, 2024

Cost: $850.00


Prerequisites: Familiarity with fundamental principles of gamma spectroscopy and Genie™ spectroscopy application software is strongly recommended, as well as fundamental use of ISOCS software.

Description: This 1-day seminar provides discussion and examples for advanced in-situ measurements. The uncertainty estimator will be used to help answer questions about complex model variables and how the efficiency changes with a modification in the sample makeup and distribution of radiation. It is assumed in this session the attendee has a general idea of how to enter data into the ISOCS software application. This seminar emphasizes how to approach an in-situ measurement that may not entirely be modeled with a simple ISOCS template or evaluate if it really is a “simple” model.

Who Should Attend: Gamma spectroscopy system operators and supervisors who are responsible for project planning prior to making in-situ measurements using ISOCS generated efficiencies as well as data reviewers, regulators overseeing the use of these measurements, and other potential advanced users.

How Will You Benefit: Attendees who complete this seminar will attain a good understanding of the variables in modeling gamma energy efficiencies that are most affected when building a model. Also covered is how to use the associated tools that will assist with modification to best match the true efficiency of the object measured. This knowledge will enable attendees to effectively use this software and interpret the efficiency calibration results and the data from spectrum analysis. Supervisors and managers will benefit from the knowledge and proficiency gained by attendees, with improved data quality for their gamma spectroscopy measurement program.

Seminar Topics:

  • What inputs have the greatest effect on the efficiency of the model.
  • How to model complicated source distributions using ISOCS geometry templates including the use of multi-efficiency.
  • Complex modeling considerations with multi-layers, absorbers, and High-Z materials.
  • How to use the ISOCS Uncertainty Estimator to help plan projects.
  • Understand the importance of the selection of gamma energies used to perform the calculations to use for efficiency calibrations.
  • Detector field-of-view.
  • Detector positioning conventions.
  • When is it best to use Massimetric (efficiency * mass, efficiency * area, and efficiency * length) measurements.
  • How to use LACE (Line Activity Correlation Evaluator) to verify correct model assumptions.

Examples will be used to demonstrate the application of the concepts.
