A very useful feature of Nucleonica is the use of nuclide mixtures. The Nuclide Mixtures app allows the user to create mixtures of nuclides and these mixtures can then be used in other Nucleonica apps.
In this new update of the Mixtures app, the use can select which data libraries are to be used to select the nuclide data. Currently the data libraries JEFF-3.1, JEFF-3.3, ENDF/B-VII.1, ENDF/B-VIII.0, 8th TORI, and ICRP-107 can be used for the nuclide data (half-lives, branching ratios, etc.).
It is also possible to convert mixtures created with a particular datal ibrary to another data library as shown in the screenshot below.
Mixtures created using a particulat data library can be converted to another lobrary.

The Karlsruhe Nuclide Chart is a well-known nuclear data collection used in education and research institutions worldwide. This paper summarises its content from 1958, with data on 1517 experimentally observed nuclides, to the latest 2022/23 edition with data on 4122 nuclides. The paper also provides an overview of the data content of the latest edition with emphasis on the data sources. The unique features of this nuclide chart are the compact presentation of the most essential and up-to-date nuclide data in small, 1.5 × 1.5 cm nuclide boxes and the availability in different printed formats. This compact data presentation allows the Chart to supplement educational and research materials in the last 65 years. In the past eleven years, the Chart’s booklet has been extended by 100 simplified decay schemes for nuclides of particular interest to understand the decay processes in more detail.

The basic idea behind the Gamma Spectrum Generator light (GSGlight) was to develop a spectrum generator with a minimum of physics (e.g. without Monte Carlo) but capable of being used with a wide variety of detectors. Such a tool is of interesting for education purposes because one can easily demonstrate the added value of different detector types that will allow resolving close-lying peaks (e.g. from the same or another nuclide).
The Nucleonica applications Gamma Spectrum Generator (GSG) and Gamma Spectrum Generator Pro (GSGPro) have been developed specifically for use with HPGe and NaI detectors. The underlying simulations are based on Monte Carlo (MC) for the background scattering within the detector, etc., and are not easily extendable to other detectors without detailed MC calcutions. The advantage of the GSG and GSGPro is that the simulations include effects such as Compton scattering, background scattering, escape peaks, natural background etc. The main disadvantage is they cannot be used for other detectors.
The current GSGlight can be used for the detectors HPGe, NaI, LaBr³, CeBr³, BGO, CdTe or CdZnTe (CZT), LYSO. Other detectors can easily be added. In the image above the spectrum of a natural uranium mixtuure using a LaBr³ detector is shown.

An educational version of the Karlsruhe Nuclide Chart – KNC light – is now availble free for education and training purposes. With this “light” version, the Chart shows:
a) nuclide selector, b) the name of the nuclide e.g. Co 60, c) the half-life 5.27 y and/or abundancies, d) the nuclide “colour” indicating the type of decay radiation, e.g. blue indicating ß- emission, e) and the nuclide box substructure indicating metastable states and branching. Help page and further information pages are in preparation.
The Chart can be scrolled manually on mobiles and/or using a mouse in the case of desktops. A Settings cog can be toggled to change the zoom factor, and show the decay mode/half-life legends,

Mobile version of the KNC “light” showing the main Chart and the Settings pages. An information button leads to further information on the App. Access to the KNC light is available through a link (given below) for browser windows or via an “App” icon for mobile devices. The app icon can be generated using the “send to homescreen” browser feature on mobiles. Alternatively, the link can be bookmarked for both desktop and mobile devices.

The TU Delft Reactor Institute has announced a new “Giga version of the Karlsruhe Nuclide Chart”. The nuclide chart is some 19 metres by 13 metres; diagonally from hydrogen to oganesson, the length is as much as 23 metres. The more than 3,000 nuclides are printed on some 100 sheets.

Happy New Year!
2023 in Review
Dear Nucleonica Users,
Since our last newsletter, there have been a variety of updates including new
applications and new products at Nucleonica.
Nucleonica Newsletter 2024
Nucleonica Online Applications Update
In 2022 and 2023 we have developed our new Shield Thicknesses Application.
Shield attenuation thicknesses are required for routine calculations in nuclear
science, radiation protection, nuclear medicine, etc. The new application can be
used to calculate the shield layer thickness for a range of shield materials. It is
also possible to include parameters such as the threshold energy, the nuclear data
used, the buildup factors and the inclusion of daughters.

Karlsruhe Nuclide Chart, new 11th Edition 2022
The 11th Edition 2022 of the “Karlsruher Nuklidkarte” has been launched and
contains new and updated radioactive decay and thermal neutron cross sections
data on 1035 nuclides (82 new nuclides) not found in the previous (2018) edition.
In total, nuclear data on 4122 experimentally observed ground states and isomers
are presented. The new chart can be ordered in English, French, German and
Spanish via our online shop http://nuklid.shop.

Nucleonica’s Periodic Table of the Elements, new 1st Edition
We have also launched the first edition of Nucleonica’s Periodic Table of the
Elements, a new product to complement our Karlsruhe Nuclide Chart in its various
forms and sizes. The data in the table is scientifically approved by Nucleonica and
contains the information on the atomic number, chemical symbol and element
name. In addition, latest data are given on the relative atomic weight, density,
melting and boiling points, ionisation potential and aggregate condition (solid,
liquid, gas) at room temperature for 118 elements.
The Periodic Table of the Elements is colour coded by type of element (e.g.
type of metal, noble gases, halogens etc.). It is is available in printed form on
our web shop https://nuklid.shop/ in four languages: English, German, French
and Spanish and printed in three sizes: A3, A1 and A0.

Nucleonica Team to provide easy and spontaneous communication between
members of the Nucleonica community (either online or offline) while using the
Nucleonica apps. Users may exchange results of calculations, their experience with
applications and so on through short messages reinforced by emojis or send files
up to a length of 2 MB while working with Nucleonica.

(Qu. FB, Germany)
For our new investigation with an X-ray detector, we tried to implement an Fe-55 source in nucleonica to produce spectra with a low energy peak at 5.9 keV. However, we did not succeed generating a spectrum with this peak using the gamma spectrum generator (GSG).
Probably there is an energy threshold or another mechanism, e.g. for Auger electrons, that is not taken into account.
What can you advise us?
