Invitation to join Nucleonica

Nucleonica - – is a first step resource in the nuclear sciences and provides you with user-friendly access to the latest reference data from internationally evaluated nuclear data. A unique feature is the wide range of validated web-based nuclear science applications. Nucleonica is already being used by thousands of scientists and students worldwide in over 90 countries

Nucleonica Homepage:

As a Nucleonica user you can:

• Keep informed with the latest news on nuclear issues

• Use internationally evaluated nuclear data in your work

• Have access to an extensive range of nuclear science applications (some modules require an annual subscription)

• Manage all your data in a single browser-based system and keep track of your recent activities

• Prepare a lecture or a training course with Nucleonica materials (graphics. etc.)

• Prepare publication quality scientific graphs

• Stay in contact with your colleagues from previous employment, workshops or conferences

• Meet scientists from your areas of interest and build up an international contact list and represent yourself and your Institute/Organisation in the international science community

Nucleonica offers you...

Data Centre Online interactive nuclide charts (based on decay modes, half-lives, binding energy, spin, partiy, etc.), reference data (datasheets, derived data, cross sections, spectral data, fission yields) and searchable databases for internationally evaluated nuclear data.

Application Centre The application modules include radioactive decay, dosimetry & shielding, fission yields, range & stopping power, reactor irradiation and nuclide depletion (with webKORIGEN), transport and packaging, library creation for spectroscopy, nuclide mixtures etc., with publication quality graphics. In addition, an advanced scripting language is available for user defined calculations and batch processing.

Knowledge Centre “wiki” technology in the NUCLEONICA knowledge centre is used for online Help, Articles, Weblinks, Forum, etc. The ease of operation makes the NucleonicaWiki an effective tool for adding/changing content – this allows the portal to grow organically and provide a powerful nuclear science collaboration platform for its users. The nuclear news aggregation service provides latest news and information on nuclear issues.

Networking centre Stay in contact with your colleagues from previous employment, workshops or conferences, meet scientists from your areas of interest and build up an international contact list, represent yourself and your Institute/Organisation in the international science community, organise your own meetings, workshops, conferences within Nucleonica – no need for your own webpage / webserver etc.

The Nucleonica 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. The Nucleonica portal can also be accessed by a variety of mobile devices
