DecayMate vs Nuclide Chart

Forget manual formulas and spreadsheet errors—get precise radioactive activity calculations instantly. DecayMate is a dedicated physics utility designed for laboratory reference and research. It streamlines the complex mathematics of radioactive decay, allowing you to focus on your inventory and calculations without the guesswork. KEY FEATURES: • Decay Calculator: Perform forward-decay calculations instantly. Input a starting activity and calculate exactly what remains after minutes, hours, or days based on standard exponential decay laws. • Target Activity Planner: Need a specific activity level at a future time? Use the backward-calculation tool to determine exactly the initial activity required to reach your target based on the isotope's half-life. • Live Tracker: Pin an active source and monitor its decay in real-time. Watch the activity decrease second-by-second on the live dashboard or via Home Screen widgets. • Custom Library: Comes pre-loaded with standard isotopes (Tc-99m, F-18, I-131, Cs-137, etc.). Need a specific radionuclide? Create and save custom isotopes with your own precise half-life definitions. • Unit Converter: Seamlessly toggle calculations between Curies (mCi, Ci) and Becquerels (MBq, GBq) anywhere in the application. • Privacy First: DecayMate operates entirely offline. Your custom isotope data and calculations are processed locally on your device and are never transmitted to the cloud.

Explore the world of atomic nuclei with the most advanced Nuclide Chart for iPad. This app offers a complete, interactive visualization of all known isotopes (over 3000), perfect for study, research, and teaching. Features: • Live Data: Direct connection to the IAEA (International Atomic Energy Agency) database for up-to-date physical values. • Interactive: Smoothly zoom and pan through the entire chart of nuclides. • Decay Chains: Visualize decay paths (Alpha, Beta, etc.) instantly – step-by-step or as a full chain. • Smart Search: Find isotopes quickly by symbol, mass, or name. • Advanced Filters: Filter by stability or decay mode (Alpha, Beta+, Beta-, Fission). • Detailed Info: Comprehensive data for every nuclide (Half-life, Spin, Binding Energy, Magnetic Moment, Atomic Mass). • Offline-Ready: All data is cached locally for instant access. Ideal for physicists, chemists, students, and anyone interested in nuclear science.
