Iron Fe
- Naturally occurring iron consists of four stable isotopes: 5.845% of 54Fe, 91.754% of 56Fe, 2.119% of 57Fe and 0.282% of 58Fe. [Wikipedia http://en.wikipedia.org/wiki/Iron]
- Sum of all reactions not given explicitly in another MT number [NNDC http://www.nndc.bnl.gov/]
Lead Pb
- Lead can be found or produced in many isotopes, with three of them being stable. The four natural isotopes of lead are 204Pb, 206Pb, 207Pb, and 208Pb with the slightly radioactive 204Pb regarded as completely primordial lead [Wikipedia http://en.wikipedia.org/wiki/Lead]
- Sum of all reactions not given explicitly in another MT number [NNDC http://www.nndc.bnl.gov/]
