(July 24) Deployment of Nucleonica Internet Version 2.0.10.1

Statistics tab

contains statistics for new modules like UNC, NRA and Cambio. A new table called Statistics1 have been added to the Personal database. A new user called Free has also been added to Users table in order to track non logged users when using UNC and NRA.


Nuclear News cache:

DisplayNucleNews.ascx change to store in the rss_cache folder a new file called nuclearnews.xml. This mean that the problem with the News has been solved. That when there is a breakdown in the web crawler, we dispaly the new from a buffer. At the present time, a file called NucleonicaNews.xml is created. If the connection fails for any reason, the application will read from the created xml file. It is impossible to test in the production server, because we need to switch off the connection to the server… If we do not see any more the label “Sorry, no news”, the problem is solved.


Korigen:

The Inhalation and Ingestion toxicities calculated by KORIGEN should be multiplied by the factor 3e-4 in order to get the toxicities in Sieverts. This was only be done for the top 10 nuclides or elements: now it is done for all the 20 nuclides or elements

An extended version of Korigen is also deployed, which displays the data of all nuclides (up to 800) and elements (up to 80) produced by the KORIGEN code. Unfortunately we don't have a licensed KORIGEN.exe yet.

(July 17) Element 112 named "copernicium"

The group led by Sigurd Hofman at the centre for Heavy Ion Research at Darmstadt (Gesellschaft für Schwerionenforschung, GSI) has just proposed the name "copernicium" for element 112 discovered in 1996. The element was produced by fusing zinc atoms with lead atoms in a particle accelerator. To date the element had provisionally been allocated the latin name Ununbium, Uub (for 112). The proposed names still has to be endorsed by the International Union of Pure and Applied Chemistry (IUPAC). The currently known isotopes of Uub listed in the 7th Edition of the Karlsruhe Nuclide Chart are shown below with their half-lives. The colours denote the main decay modes (yellow: alpha decay, green: spontaneous fission)

Commemorative book to mark the 50th Anniversary of the “Karlsruher Nuklidkarte”.

More information on the discovery of this new element can be found in the recent commemorative publication to mark the 50th Anniversary of the “Karlsruher Nuklidkarte”. This provides a broad, state of the art overview of scientific research in the nuclear sciences and in particular in the discovery of super heavy elements. The publication provides a broad, state of the art overview of scientific research in the nuclear sciences. Chapter introductions were written by R. Bimbot (France), M. Lewitowicz (France), B. Jonson (Sweden), G. Audi (France), S. Banerjee (India), R. Leonardi (Italy) together with Nobel laureates J. I. Friedman (USA) and G. ‘t Hooft (Netherlands).

In total there are 30 scientific articles covering fundamental and theoretical aspects of nuclear physics and chemistry including the discovery of new elements and decay modes, neutrinos, quarks, antimatter, and dark matter. Technological developments are described in a series of articles ranging from space radiation biophysics and health care to archaeological dating, forensics and cultural heritage.


For further information on the book, see Flyer

To celebrate the 50th anniversary in 2008, a special one-day event was organised by ITU on 9th Dec. 2008 in the Gartensaal of the Karlsruhe Schloss (castle). Presentations were made by a number of renowned scientific experts: A. Zichichi (CERN), A. Popeko (Joint Institute for Nuclear Research, Dubna), F. Bosch (GSI Darmstadt), F. K. Thielemann (University of Basel), W. Kutschera (University of Vienna), M. J. Garcia Borge (Instituto de Estructura de la Materia, CSIC, Madrid), A. Türler (University of Munich), A. Marinov (University of Jerusalem), G. Drexlin, KIT Karlsruhe. During the event, the special commemorative publication [1] to mark the 50th Anniversary of the Karlsruhe Nuclide Chart was presented.

(June 2) Major Nucleonica Deployment: Version 2.0.0005.0001

Main new features:

  • Dosimetry & Shielding:

A third mode of operation is introduced, to calculate the strength of a source from a measured dose rate at a given distance and behind a shield of known material and thickness.

  • Nuclide Datasheets:

The title of the page is changed to Nuclide Datasheets. The first tab is now called Reference Data. The tab Average Cross Sections becomes now Cross Sections.

Reference Data:

For natural abundancies, the unit "%" is replaced by "atom %". For nuclides without a half-life, that is with T_HALF=Null, the data sheet was not displayed: now the basic known data are displayed (e.g. Li-3, Uuo-294...). For nuclides with unknown half life (T_HALF=Null), the activity will not be displayed; activity = 0 is now only displayed for stable nuclides.

The specific γ dose rate is calculated in Air with 1 m thickness, and 15 keV threshold, but for γ - and X-rays, rather for γ only up to now.

For parent nuclides the first column is now entitled Type of parent decay

Cross Sections:

The introductory text for the Graph buttons is now more explicit and visible. The cross section diagrams are nuclide specific; images displayed by clicking one of the buttons Pointwise, Average or (x,xn) cross-sections now take into account the isomeric state of the selected nuclide.

Radiations, 8th table of Isotopes:

The radiaton mode ec, β+ or β- was added for each given emission end point.

  • Mass Activity Calculator:

A new source strength unit (µSv/h for dose rate) is introduced. Conversion is made, using a given distance from the source (100 cm by default) and the Equivalent Dose Rate Constant (µSv/m²/MBq/h) in vacuum.

  • Scripting:

Is now released for all users. In addition to the Specific Gamma Dose Rate calculated at 1 m in air, the Equivalent Dose Rate Constant in vacuum is now available as nuclide property. All Dose rates are computed for γ and X-rays with 15 keV threshold energy.

  • webKorigen:

For EFR calculations, the reactor parameters are initialized to 40 % electrical efficiency, 15 tons initial HM, a neutron flux of 3E15 n/cm²/s and 3 cycles (of 1 y each)

Step 4, Nuclide/Element diagrams: the graphe title displays the reactor and spectrum types even in the case of flux mode calculation

  • Nuclide Explorer:

Selection data such as Jπ and BE are shown als for isomers.This data is also shown in the Nuclide box as an application logo. The Chart axes are extended for x up to N=177 and for y up to Z=118. Element 118 - Uuo - is added as a rare gas on the Z-axis. For BE in isomer boxes, only a 4 digit precision is kept and the unit is suppressed. The missing magic line at N=152 is added to the Nuclide Explorer Charts.

  • Nucleonica Networking Portal & Nuclear Science Portal:

Top menu - The Home page is now called Networking, the application Portal is now called Nuclear Science

A Privacy statement is added and the Legal notice link is updated

  • Portal:

The new item FAQ is added as a link to the wiki's FAQ to the left side navigation menu

The Ask an Expert page is extended by a new item more "Ask an Expert"... as a link to the wiki's Ask_an_Expert

(March 19) Call for tenders: Karlsruhe Nuclide Chart

Development of a web-based management tool for data management and printing of the Karlsruhe Nuclide Chart

The Institute for Transuranium Elements (ITU) is planning the development of a web-based Karlsruhe nuclide chart (KNC) application to assist the KNC team with the data management for present and future editions of the KNC. In addition, of key importance in this project is the facility to generate high definition files (e.g. pdfs) suitable for printing purposes from the electronic databases. These various printed versions of the Karlsruhe nuclide chart are for world-wide distribution. The applications should be developed within the Nucleonica ( www.nucleonica.com) nuclear science portal (the portal provides a customisable, integrated environment and collaboration platform for the nuclear sciences using the latest Internet 'Web 2.0' technology).

The contract will cover the development of various web applications (web-based Karlsruhe nuclide chart with full editing features, web-based energy level diagrams, web-based KNC database, etc.) and the facility to generate high definition nuclide chart files which can be printed as fold-out charts, wall-charts and 'roll' charts, as well as technical meetings with the ITU KNC team.

(July) "Nucleonica at a glance" - brochure now available

Summary: NUCLEONICA is a new nuclear science web portal from the European Commission’s Joint Research Centre. The portal provides a customisable, integrated environment and collaboration platform for the nuclear sciences using the latest internet “Web 2.0” technology. NUCLEONICA is aimed at professionals,academics and students working in the fields of nuclear power, health physics and radiation protection, nuclear and radiochemistry, and astrophysics. In addition, the portal will find application in the life sciences (e.g. biology, medicine, agriculture) and the earth sciences (geology, meteorology, environmental science). It is also used as a knowledge management tool to preserve nuclear knowledge built up over many decades by creating modern web-based versions of so-called legacy computer codes. NUCLEONICA provides “software as a service” on the web rather than through installed software, adding a greater level of stability and security and avoiding version compatibility and update problem. In addition, all NUCLEONICA’s web applications are browser and operating system independent and can therefore be accessed by most web browsers. The NUCLEONICA portal can also be accessed by a variety of mobile devices. http://www.nucleonica.com:81/wiki/index.php/Help:Nucleonica_at_a_glance

(January) Polonium-210 Updated

The element polonium was first discovered by Mme. Curie in 1898 while seeking the cause of radioactivity of pitchblende (uranium ore). The element is named after Poland, Mme Curie’s native country. There are now 35 known radioactive isotopes of the element polonium – there are no stable isotopes. Polonium-210 (Po-210) is a naturally occurring radioactive material. Although it decays to stable lead-206, it is constantly being produced in nature from the decay of uranium-238 – the main component of uranium in the earth. Due to this “equilibrium”, the concentration of Po-210 in nature is approximately 75 µg of Po-210 for every ton of uranium-238. In terms of disintegrations per second or activity, this corresponds to 1.2E+10 disintegrations per second or 1.2E+10 Bq (1 Becquerel, Bq = 1 disintegration per second).
