Unidentified peaks in I-125 spectrum

May 30th, 2018
by Joseph Magill

Qu. (from Z. S. JRC Karlsruhe) Using the Gamma Spectrum Generator app in Nucleonica I have created a gamma spectrum for I-125 (shown below). Comparing the results from the Nuclide Datasheets++, I find the three lines at approx. 35, 31, 27 keV (see inset from the Datasheets++). Where do the extra peaks at approx. 21 and 17 keV come from?

The additional lines from the I-125 spectrum are X-escape peaks.

Ge emits X-rays at approx. 10 keV (Intensity 48%), 11 keV (intensity 6%), and about 1.2 keV (Intensity 0.5%) so Xesc-peaks can be expected at:
21 keV = 31 keV – 10 keV
20 keV = 31 keV – 11 keV and 21 -1.2

17.6 keV = 27.5 – 10 keV
16.5 keV = 27.5 – 11 keV and 17.6 – 1.2

25.4 keV = 27.5 -1.2 keV
The relative intensities correspond about to the relative Ge X-ray intensities.

e-Ship streamlined

April 30th, 2018
by Joseph Magill

Following the CERN training course in April, the e-Ship++ transport assistant has been streamlined and made more coherent from a training perspective.
The transport characterisation based on A1 and A2 coefficients and activity limits has been more clearly separated from the source characterisation based on Swiss RPO. This allows new users to concentrate on the transport aspects of the package.

The source characteristics are an advanced option which allow users to estimate the radiological impact of the shipment in the event of a release of radioactivity into the environment. The source characterisation also allows to declassify materials according to clearance limits and authorisation limits, and calculate the surface and air contamination limits.

Nucleonica Training Course, CERN, 16-17 April 2018

April 20th, 2018
by Joseph Magill

Introduction to Nucleonica: Core Applications and Tools, 16-17 April, CERN, Switzerland, 2018.
This 2-day course focused mainly on the Nucleonica core applications with emphasis on Case Studies. A detailed description of nuclear data with particular reference to the various Nucleonica nuclear databases was given. Core applications were demonstrated through the use of the Radiological Converter, Nuclide Mixtures, Decay Engine++, and Dosimetry and Shielding H*(10). The new e-Learning centre to support the Nucleonica applications was described.
IMG_20180416_144805 A key lecture with exercises was given by Mr. Yann Donjoux (CERN) on the e-Ship++ radiological transport assistant application in Nucleonica.
A special session was devoted to gamma spectrometry tools including the Gamma Spectrum Generator, Gamma Library, Cambio and WESPA. The latter tools (Cambio and WESPA) were used for the identification nuclear and radioactive materials.
In total, 11 persons took part in the course from CERN.
Speakers included Mr. Y. Donjoux (CERN) in addition to Dr. J. Magill and Mr. R. Dreher from the Nucleonica team.

New e-Learning Training Centre for Nucleonica Applications

April 3rd, 2018
by Joseph Magill

A new eLearning training centre has been created to assist users to become familiar with the most important features of the Nucleonica applications. The eLearning centre can be used directly in “live” dedicated training courses for organisations or independently as “self-learning” modules in Nucleonica. The eLearning centre consists of the following online “training courses”:
– 1-day training course; – 2-day training course;
– Advanced course; – Nuclear security exercises (restricted)
In addition, presentations for individual applications are also available.

The training materials consist of online “slides” for each application including:
1. Title, 2. Contents, 3. Description of the main features, 4. Summary,
5. Exercises (with answers), 6. Additional files for use with the Exercises
In contrast to the wiki, which provides a full comprehensive technical documentation of each application, the eLearning centre focuses more on the main features of the application and usability, together with exercises (with answers).
