To explain your point, draw on information about how the Code of Hammurabi emerged, the overall theme, and what you see as some of the more striking statutes listed.

Heating an item to 500 degrees Celsius or higher releases the trapped electrons, producing light.

It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record.

Thus dating that particular tree does not necessarily indicate when the fire burned or the structure was built.

The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice.

K–Ar dating was used to calibrate the geomagnetic polarity time scale.
