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.

What's New in Version 1.3

Tested under iOS 10.2
New element names validated by IUPAC (International Union of Pure and Applied Chemistry)
Displays decay chains on the chart view
