Iridium 192 Half Life. The Chicxulub crater (IPA [tʃikʃuˈlub]) is an impact crater buried underneath the Yucatán Peninsula in Mexico Its center is offshore near the communities of Chicxulub Puerto and Chicxulub Pueblo after which the crater is named It was formed when a large asteroid about 10 kilometers (62 miles) in diameter struck the Earth The date of the impact coincides precisely.

Atomic weight ratio of the average mass of a chemical element’s atoms to some standard Since 1961 the standard unit of atomic mass has been onetwelfth the mass of an atom of the isotope carbon12 Atomic weight is measured in atomic mass units (amu) also called daltons.

Halflife 700 million years Uranium238 (U238) Halflife 447 billion years Mode of decay Alpha particles Chemical properties Weakly radioactive extremely dense metal (65% denser than lead) What is it used for? Uranium “enriched” into U235 concentrations can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines It also can be used.

Halflife 806 days Mode of decay Beta particles and gamma radiation Chemical properties I131 can change directly from a solid into a gas skipping the liquid phase in a process called sublimation I131 dissolves easily in water or alcohol I131 readily combines with other elements and does not stay in its pure form once released into the environment.
