A level physics carbon dating

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Ionization Inverse Square Law Interaction of RT/Matter Attenuation Coefficient Half-Value Layer Sources of Attenuation -Compton Scattering Geometric Unsharpness Filters in Radiography Scatter/Radiation Control Radiation Safety Radio-carbon dating is a method of obtaining age estimates on organic materials.

It consists of an ionisation chamber linked to a simple electronic alarm circuit The Americium ionises the air between the plates, causing a current to flow.The most common and accepted method of 'absolute geologic dating' (establishment of actual age) is based on the natural radioactivity of certain minerals found in rocks.As the rate of radioactive decay of any particular isotope is known, the age of a specimen can be worked out from the ratio of the remaining isotope and its decay product.Electrical circuitry is then set up to ensure that a constant rate is maintained.If the rate is too low the rollers automatically move closer to each other (making the paper thinner) and vice versa.
