- Tin-121m
Tin-121m is a radioisotope and
nuclear isomer oftin with ahalflife of 43.9 years. In a normalthermal reactor , it has a very lowfission product yield ; thus, this isotope is not a significant contributor tonuclear waste .Fast fission or fission of some heavieractinides will produce 121mSn at higher yields.ee also
