## Description

Isotope Browser, developed by the International Atomic Energy Agency's Nuclear Data Section, offers comprehensive data on more than 4,000 nuclides and isomers. The extension features an interactive Chart of Nuclides with zoom and tap capabilities alongside a Periodic Table of Elements for seamless navigation.

Users can filter nuclides based on half-life, decay mode, radiation type, and energy. Results are displayed in a scrollable list with detailed pages linking to data sources. Visualizing filtered nuclides on the chart enhances understanding. With an embedded database, the extension performs optimally offline, ensuring access to the most recent, reliable nuclear data at any time.

## Review summary

Isotope Browser is widely praised as a free, fast, and comprehensive reference for nuclear data, offering up-to-date information on isotopes, half-lives, decay modes, and decay chains. Reviewers value its decay-chain visualization and Segre chart, plus broad coverage including medical isotopes and fuel/dating data. It’s described as extremely useful for work and studies and often preferred over traditional documents. However, several users note UI/visual design improvements could be made and report stability issues such as crashes or graphics glitches, though updates have addressed some concerns.

### Pros

- Comprehensive, up-to-date isotope data including half-lives, decay modes, and decay chains.
- Powerful features like decay chains and the Segre chart.
- Free to use and readily accessible.
- Very useful for professionals and students; quick reference.
- Wide coverage (medical isotopes, fission fuel/waste, dating methods) and up-to-date elements.

### Cons

- UI/UX could be improved; colors and overall design feel outdated.
- Occasional stability issues, including crashes and graphics glitches.
