Breaking up is easy to do for unstable isotopes such as uranium-235 and nitrogen-17. Everyone from nuclear engineers to health physicists can corral basic data about these fleeting isotopes and their more stable counterparts at NuDat from Brookhaven National Laboratory in Upton, New York. For nearly 3000 isotopes, the site records properties such as spin-parity, half-life, mass, and type of radioactive decay. To learn more about a particular breakdown, try the Decay Radiation function, which supplies values such as energy release and radiation dose.
