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).

Half-lives of the nuclides Rh-102 and Rh-102m

March 13th, 2018
by Joseph Magill

Qu. (from M. D. KTE Karlsruhe): In using the platform Nucleonica I found some inconsistent data. The half-lives of the nuclides Rh-102 and Rh-102m are not the same in the different specified databases. The half-lives of Rh-102 and Rh-102m seem to be inverted at „JEFF-3.1“ in comparison to „ENDF/B-VII.1“ or „Nubase 2012“. Do you have information which the correct data for these two nuclides are?

Ans. (Nucleonica Team): The most relevant information on the radionuclide Rh-102, 102m half-lives can be found in the paper: M. Shibata et al. Applied Radiation and Isotopes Volume 49, Issue 12, 1 December 1998, Pages 1481-1487
Beta-decay half-lives and level ordering of Rh-102m,g. link
Citation from the abstract of this paper: Beta-decay half-lives of the ground state and an isomer of Rh-102 have been determined 207.3(17) d and 3.742(10) y, respectively, by γ-ray decay curves following each β-decay. It has been found that a state (2−) which has a shorter half-life (207.3 d) is the ground state from the result that the half-life of the 41.9 keV isomeric γ-transition was equal to 3.742 y. It has also been confirmed that the 41.9 keV transition is certainly an isomeric transition with X–γ coincidence measurement.

The data in Karlsruhe Nuclide Chart 10th edition, recent NUBASE file and ENSDF are based on this research. In JEFF3.1 the ground and metastable states were allocated incorrectly. We recommend to use the latest information based on the above mentioned research and summarised in the Karlsruhe Nuclide Chart as shown in the figure.

Exemption & Authorisation Limits

February 20th, 2018
by Joseph Magill

Based on the recently released Swiss RPO data (January 2018), this new Nucleonica application provides data on exemption and authorisation limits for radioactive materials. Based on assessment values for dose coefficients for ingestion and inhalation, together with specific dose rates at various tissue depths for external radiation (h10, h0.07, and hc,0.07), values are given for the operational radiation protection quantities together with exemption and authorisation limits and guidance values.
EandA-AvIn summary, the application has the following main features:
– Based on the dose coefficients for ingestion and inhalation, together with specific dose rates at various tissue depths for external radiation (h10, h0.07, and hc,0.07), exemption limits LE, authorisation limits LL, and guidance values for airborne CS and surface contamination CS are given.
– From the above quantities, and the user specified activity (Bq) and surface contamination (Bq/cm2), the total doses for ingestion, inhalation and external radiation (H10, H0.07, and Hc,0.07) are calculated.
– The latter quantity, Hc,0.07 allows the user to calculate the dose rate to skin following a spill of radioactive material.
– a table of the Swiss Operational radiation protection data is provided together with links to the corresponding web pages in French and Germany are given.
