Expect Variety as Radio Halo’s Song Catalog covers many different genres and decades of music, including Classic Rock, 80’s Metal, Alternative Rock, Punk, Ska, Modern Rock, Top 40, Pop, and Dance.A parent radioactive atom decays into a daughter atom in various ways, one of which is by the emission of an alpha particle from the parent atom's nucleus.The half-life of a given type of radioactive atom is the time during which half the atoms in any collection will decay. Half-life, decay rate, and decay constant are closely related quantities.If we assume that the decay rate has not changed over geologic time,* and if we measure 1) how much of a parent in a rock has decayed into its daughter; and 2) the current rate of this decay, then we can, it is generally believed, assess the date when the parent was incorporated into the rock—that is, the date when the rock was formed.They are building their reputation around their signature sound and high energy performances.

The alpha particles are emitted randomly in all directions but stop at the same distance from the parent (Figure 1).

Radiohalo research is a relatively new area of scientific investigation, the significance of which has been shown by authors such as Snelling and Gentry.

This study examines the prevalence of the radiohalos of polonium isotopes and uranium isotopes within biotite flakes generated by radioactive zircon crystals.

The radiohalos result from damage caused by the emanation of hundreds of millions of alpha particles from the zircon crystals during the decay process.

The samples were obtained from drill cores granted to us by the Drill Core Library in Hibbing, Minnesota.
