Webinar on the Characterization of Contamination and NORMs with Portable High-Resolution Radionuclide Identification Devices
Background
IAEA has conducted a series of webinars on the enhanced use of HPGe nuclear security instruments. The presented topics have nuclear security aspects in terms of possible contamination during the transport of radioactive materials, their storage, local accidents, as well as potential misuse of Naturally Occurring Radioactive Materials (NORM). Specific characterization cases have different approaches in measurement with respect to geometry and distribution of radioactivity.
Previous webinars provided an overview of general approaches to estimate activity in a general container containing radioactive material, and determine the uncertainty in the estimation, as well as conduct analysis using an example of open-source gamma spectroscopy software (InterSpec).
This follow-on webinar will focus on measurements of field contamination caused by artificial radionuclides or the characterization of areas with excessive concentration of NORMs, including demonstration of activity estimation for radioactive contamination caused by man-made radionuclides, and characterization of areas with high concentration of NORMs.
Objectives
The objective of the webinar is to provide an overview of the approach for measurements of terrestrial contamination and characterization of NORMs with portable HPGe detectors.
