The measurement of radionuclides present within the surrounding sediment can be calculated either byin-situgamma spectrometry or high-resolution gamma spectrometry in the laboratory to identify the annual Dose Rate (Dr) of ionising radiation, Gy kyr-1, after which the age of the sample can be calculated using the equation: This equation very simply expresses the calculations necessary, but it is important to be aware of the factors influencing the two values used. Quat. & Tchonka, J. Optical dating: K-feldspars optical response stimulation spectra.

Cells are transfected with a plasmid containing the reporter, Reactive Oxygen Species (ROS) are chemically reactive molecules containing oxygen. Optically stimulated luminescence (OSL) dating or optical dating provides a measure of time since sediment grains were deposited and shielded from further light or heat exposure, which often effectively resets the luminescence signal (Fig.1).
