WebA fissile isotope, such as uranium-235, is one that is sufficiently large and unstable to undergo such a chain reaction, as opposed to the more common and less unstable uranium-238. Ponytail fear that her raspberries have too many unstable isotopes so that her fields risk undergoing a similar fission-driven chain reaction. WebList of isotopes Uranium ( 92 U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found.
