内容提要

Nuclide chart of all known isotopes (3343). You can zoom in and out and move in all directions.
Touch a cell to get all data about a nuclide as well as its location in Mendeleiev's periodic table.
You will have to purchase the extension to see the description of isotopes of elements above hydrogen.
Select a disintegration mode and thus follow a disintegration chain.
Search elements by their name or atomic number and display their isotopes list.
Some isotopes were cited after Tchernobyl and Fukushima accidents (Iodine-131, Cesium-137 and 134). Find out their half-lives (time it takes to decrease by half) and their child nuclide.

Informations provided:
- Atomic number (number of protons)
- Number of neutrons
- Mass excess
- Binding Energy by nucleon
- Beta Decay Energy
- Atomic Mass
- Spin
- Half-life duration
- Abundance
- Decay modes and branching (except isomeric transitions (IT) because they do not product a new isotope but instead a more stable configuration of the same one)

The informations were extracted from the NuDat 2 database of the National Nuclear Data Center (Brookhaven National Laboratory).
Furthermore, four candidates for the island of stability are displayed as a guidepost with the terms "not yet observed" instead of the half-life duration.
