However, to read any clock accurately we must know where the clock was set at the beginning.

Most people think that radioactive dating has proven the earth is billions of years old.

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).

The object's approximate age can then be figured out using the known rate of decay of the isotope.

For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.

It is not affected by external factors such as temperature, pressure, chemical environment, or presence of a magnetic or electric field.
