Today radiometric dating places absolute dates on the relative time scale.

The phenomenon of emitting penetrating, ionizing radiation was given the name radioactivity by the Curies.

The Curies found that the radiation was proportional to the Uranium content of the compound.

There are two definitions of half-life, but they mean essentially the same thing.

Half-life is the time taken for: Different radioactive isotopes have different half-lives.

Rontgen used the mathematical symbol for unknown to name this energy X-rays.

The interest in Rontgen’s discovery would launch the second scientific revolution; the first being launched by the work of Galileo (Asimov, 1984, pp 514-515).

This source of energy caused barium platinocyanide coated on paper to luminance.

Furthermore, this energy could penetrate cardboard and even walls to fluoresce barium platinocyanide.

They break down and change into a completely different type of atom. The radioactivity of an object is measured by the number of nuclear decays it emits each second – the more it emits, the more radioactive it is.
