WebA radioisotope is an energetically unstable atom that will achieve a stable or more stable, lower-energy state (transitioning from a parent to a daughter state) by releasing (radiating) energy (radiation), in some form (e.g., emitting a gamma ray, positron particle, or beta particle, as discussed later). WebMost therapeutic radioisotopes are either beta or alpha emitters. Beta emitters release highly energetic electrons that can penetrate several millimeters of tissues depending on their maximal energy emission (E m a x _{max} m a x start subscript, m, a, x, end subscript). Alpha emitters release large helium nuclei into the surrounding tissues.

It accounts for about 80% of all nuclear medicine procedures and 85% of diagnostic scans in nuclear medicine worldwide. WebIsotopes of uranium. 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. falafel 54 menu
