All 100 atoms are still radioactive parent, which means the mineral was just "born". Perhaps this mineral was collected from a volcano sitting directly on a hot spot. Sample B: Parent = 5 atoms, Daughter = 5 atoms Age = _ exactly 200 yrs old ____ This sample began with 10 atoms of radioactive parent (5 parent + 5 daughter).

The Leakage of Helium from Radio-Active Minerals
It was foutnd that after a radio-active mineral had been powdered, helium was evolved from it, rapidly at first, then at a diminishing rate. The following observations illustrate this. A quantity (337 grammes) of monazite from the Transvaal was powdered and passed through a wire-gauze sieve of 120 threads to the inch. This took about onie hour.

· Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral''s composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive.

A List of Radioactive Elements
· These radioactive elements are produced in nuclear reactors and accelerators. There are different strategies used to form new elements. Sometimes elements are placed within a nuclear reactor, where the neutrons from the reaction react with the specimen to form desired products. Iridium-192 is an example of a radioisotope prepared in this manner.

IMPORTANT INFORMATION REGARDING RADIOACTIVE MINERAL …
Naturally occurring radioactive minerals, in quantities that would normally be used for scientific study or kept in a mineral collection, pose little health hazard when handled properly. Specimens should be stored a reasonable distance away from a place where you would spend a lot of time each day, i.e., your work area, office, or bedroom.

There simply is none left to form minerals. There are four main radioactive isotopes that have lasted as long as the Earth: Uranium-239 (over 99% of all uranium) with a half-life of 4.5 billion years. Uranium-235 (less than 1% of all uranium) with a half-life of 700 million years. Thorium-232 ( of Thorium) with a half-life of 14 billion years.
