Radioactive decay dating game


It is assumed that we are dealing with a closed system—no loss of either parent or daughter elements has occurred since the study material formed.No scientist can guarantee that any sample can be considered a closed system unless it was isolated from its environment when it was formed.A short half-life, such as a few hours, means that the radiation is reduced to harmless levels quickly.

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

the elements beyond bismuth (Bi) in the Periodic Table of the Elements display radioactivity.

There are natually occurring radioactive isotopes of many of the other elements as well.

Specimens would then look much older than they actually are.
