Nuclides++ is powered by an embedded database derived from the NNDC NuDat 2.6 compilation for the display of atomic and nuclear data + emissions data + synthesized emissions spectra

Multiple Chart Formats:
● Karlsruhe and KAPL (GE) chart formats that display different nuclear properties and processes

Nuclear Data:
● Nuclides and Isomers - abundance and/or halfLife, mass, spin and parity, parents and progeny...
● Beta and Alpha particles; - parent nuclide or isomer, energy, and yield
● Gamma rays; - parent nuclide or isomer, energy, and yield, cascade coincidence information
● Prompt gamma-ray emissions (energies and yields) from 255 stable and long lived nuclides
● Fission yield data (thermal, fast, and 14 MeV; independent and cumulative) for the nuclides: U-233, U-235, U-238, Np-237, Pu-239, and Pu-240

Additional Resources:
● Summary decay schemes for A=1 to A=277
● Natural decay schemes for the Th-232, U-233, U-238, and U-235 decay chains
● Atomic X rays and elemental abundances

Included Tools:
● Synthetic spectra for emitted Alphas, Betas, and Gamma rays (Ge and NaI resolution)
● Nuclide Identification possibilities via a constrained database search based on observed gamma rays in a spectrum and some knowledge of the history of the spectrum. Useful items would include a minimum half life (estimated from the decay time), and possible modes of generation (nuclear reactor, accelerator, natural, etc.).
● Decay Calculator for simple and complex decay chains

What’s New

Version 2.12

Added a "Quick Links" contents page to the PDF file of Summary Decay Schemes.
● The links are every 10 A values (10, 20, 30 ... 270) so that by selecting the link closest to the A value of interest, you are never more than a few pages away from the Decay Scheme of interest.
● Each of the linked pages contains a "TOP" link back to the contents page.

Waste of money

Not much better than a scanned copy of chart of Nuclides. You have to scroll through a large document to find the decay chain. You might as well get the book.

Handy Tool for Nuclear Scientists

The software provides a convenient portable version of the chart of the new guards. It includes information about the types of radiation for each of the radionuclides it also provides the decay chain charts for all the natural occurring radioactive parents.

There is a version of the program that runs on standard PCs. This is a great accompaniment when you're on the move and need to look up some information quickly.

I highly recommend it for anybody involved in gamma, alpha or beta spectroscopy and measurements. It is a useful tool for environmental studies, nuclear power plants and national / homeland security applications.
