World’s oldest periodic table chart found in St Andrews

January 22nd, 2019

A periodic table discovered at the University of St Andrews is thought to be the oldest in the world. Following Menedleev’s famous discovery of periodicity in the chemical elements in 1869, a number of such periodic tables were created. The St. Andrews periodic table is similar to Mendeleev’s second table from 1871. Original_PT2Periodic Table discovered at St. Andrews University, Scotland (Courtesy St. Andrews University).
The United Nations has designated 2019 as the international year of the Periodic Table of chemical elements, recognizing it as an instrument ‘central to linking cultural, economic and political aspects of the global society through a common language’.

Karlsruhe Nuclide Chart (Contour Chart) at URENCO, Netherlands

January 14th, 2019

Nucleonica has arranged the installation of a “contour” version of the Karlsruhe Nuclide Chart at the URENCO premises in Almelo, Netherlands.
The Chart was produced using a 4mm Dibond aluminium plate “cut-out” to fit in a space of height 2m and width 5m and assembled a small distance from the wall. The text is cut from adhesive foil and glued directly on the wall.

Nucleonica Newsletter 2019

January 6th, 2019

Dear Nucleonica Users,
Hopefully you had a great start into the New Year, and we wish you every success in 2019. For the Nucleonica Team, a major focus over the past year was the development and improvement of new and existing applications. Detailed information on these activities is described in this Newsletter.
A highlight in 2018 was the launch of the new 10th Edition of the Karlsruhe Nuclide Chart in early 2018. You can order your copy here.
A further highlight was the development of a new online e-Learning Training Centre, making the Nucleonica product knowledge more transparent and accessible.
NN2019The Nucleonica Team would like to thank you for your continued support.
Best wishes for 2019, Sincerely yours,
Joseph Magill, Managing Director

Neutron dose rate app extended to reference neutron sources

December 13th, 2018

The neutron dose rate application, previously restricted to monoenergetic neutrons, has been extended to include the spectrum averaged ambient dose equivalent coefficients for common neutron sources. This allows the user to calculate ambient dose rates for the following reference radionuclide neutron sources:
– Cf252;
– Cf252 (D2O moderated);
– Am241-B; and
– Am241-Be
NDR_2 In the example above, the neutron dose rate for 1 g Cf-252 at 1 m is 2.65e7 µSv/h and results from a neutron source strength of 2.40e12 neutrons s-1 at the source and 1.91e7 neutrons cm-2 s-1 at 1 m distance from the source.

ENDF/B-VIII.0 (2018) decay data now available in Nucleonica

November 30th, 2018

On February 2, 2018, CSEWG released its latest revision of the ENDF/B library, ENDF/B-VIII.0.
The ENDF/B-VIII.0 (2018) decay data sublibrary is now available in Nucleonica in addition to the previously used decay data library JEFF3.1, and EBDF/B-VII.1. It is now possible to compare and contrast the main European (JEFF3.1) and American (ENDF/BVII.1, ENDF/B-VIII.0) data libraries for differences in half-lives, branching ratios, energies and emission probabilities of the emitted radiations, etc. using Nucleonica’s user friendly tools. This data comparison can be accessed through the Options tab of the Nuclide Datasheets++ application.ENDFB8

Nuclear Security training course at BfS, Berlin 2018

November 9th, 2018

Nucleonica Training on Nuclear Security, 7-8 November, BfS Berlin, 2018
This 1-day training course took place at the offices of the Federal Office for Radiation Protection (Bundesamt für Strahlenschutz BfS) in Berlin, during the 7-8 November 2018. This was an intermediate level training course which 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 Nucleonica applications such as the Radiological Converter, Nuclide Mixtures, Decay Engine++, and WESPA++. The new eLearning centre in Nucleonica was described.BetasinTissueSimulation of the Stopping of 500 keV beta particles in 1 mm tissue using Nucleonica’s Virtual Cloud Chamber.

A major focus of the course was on nuclear security related exercies on the identification of suspected nuclear and radioactive materials using Cambio and WESPA++.
In total, 10 persons took part in the course from the various BfS locations in Germany.

November 5th, 2018

Introduction to Nucleonica: Core Applications and Tools, 29-30 Oct. 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. P. Bertreix (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.
Speakers included Mr. P. Bertreix (CERN) in addition to Dr. J. Magill and Mr. R. Dreher from the Nucleonica team.

Cambio++ files saved directly in WESPA++

October 19th, 2018

Spectrum files with various data formats uploaded into Cambio++ and converted to (IAEA) .spe format can now be saved directly in WESPA++. This avoids downloading the file and then uploading again into WESPA++.
The image shows an uploaded file (ORTEC_CHN.Chn) and the converted file (ORTEC_CHN.Spe) in (IAEA) .spe format. The converted file .spe can be saved directly in WESPA++ by clicking on the Save to WESPA++ button.

Server Issues

September 17th, 2018

On Thursday 13 Sept. 2018, there was a complete failure of the main Nucleonica production server (www.nucleonica.com). The server and hard drives had to be completely replaced. The server was reinitialized with the latest Windows Server giving users the benefit of the latest server technology.
In the meantime all problems have been resolved. The Nucleonica Team apologizes for any inconvenience caused during the down time.
