WebUranium in the Environment. All three naturally occurring uranium isotopes (238 U, 235 U, and 234 U) have a very long half-life (e.g.,, 4.47×10 9 years for 238 U). Because of this very long half-life, uranium is weakly radioactive and contributes to low natural background radiation levels in the environment. These isotopes are alpha radioactive (emitting alpha … Web4 feb. 2024 · The term "isotope" was introduced by the British chemist Frederick Soddy in 1913, as recommended by Margaret Todd. The word means "having the same place" from the Greek words isos "equal" (iso-) + topos "place." Isotopes occupy the same place on the periodic table even though the isotopes of an element have different atomic weights. budleigh salterton to lyme regis

During the alpha decay steps, the zircon crystal experiences radiation damage, associated with each alpha decay. This damage is most concentrated around the parent isotope (U and Th), expelling the daughter isotope (Pb) from its original position in the zircon lattice. In areas with a high concentration of the parent isotope, damage to the crystal lattice is quite extensive, and will often interconnect to form a network of radiation damaged areas.
