About this app

Provided by the Nuclear Data Section of the International Atomic Energy Agency, the app gives properties of more than 4 000 nuclides and isomers.

A Chart of Nuclides, with zooming and tapping enabled, and a Periodic Table of Elements are included to allow easy selection and navigation.

Filter criteria on half-life, decay mode, radiation type and energy can be selected.
Summary data are presented in a scrolling list, with a details page for each nuclide containing web links to the data sources and further information.
The filtered nuclides can be visualised on the Chart of Nuclides.

Data are taken from the most recent and reliable sources, and optimal search-and-retrieve performance is achieved with an embedded database, meaning that no network connection is required.

Pretty good. Very, very convenient. Also, it's very fun to navigate through isotope chart, and decay chains are super simple to navigate.

First of all I would like to extend my gratitude to the developers of such an useful android app. Further, on a light note, I'd like to bring their attention to some of the erroneous entries made for the 'end point energy' of some beta emitting radionuclide like F-18, Ga-68, etc. Regards.

Thank you very much indeed for reporting this mistake. The new version 5.14.74 addresses the issue. Please note that the labels on the beta radiation detail have changed, check the new definitions on the guide

After reporting problems with version 5.0.50 released on 19-Mar-2019, the authors reposted an earlier version within 12 hours. I now have full functionality of this excellent program. I am a Health Physicist involved in radiation protection, and I view Isotope Browser as a must-have program for radionuclide decay characteristics. Thank you IAEA.
