What type of radiation is used in carbon dating

A commonly used radiometric dating technique relies on the breakdown of potassium (Ar in an igneous rock can tell us the amount of time that has passed since the rock crystallized.If an igneous or other rock is metamorphosed, its radiometric clock is reset, and potassium-argon measurements can be used to tell the number of years that has passed since metamorphism.A stronger magnetic field deflects more cosmic rays away from the Earth.Overall, the energy of the Earth's magnetic field has been decreasing,[5] so more C is being produced now than in the past.When living things die, they stop taking in carbon-14, and the radioactive clock is "set"!Any dead material incorporated with sedimentary deposits is a possible candidate for carbon-14 dating.

So, we have a “clock” which starts ticking the moment something dies.Furthermore, different types of plants discriminate differently.This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.This will make old things look older than they really are.

Also, the Genesis flood would have greatly upset the carbon balance.

Radioactive elements were incorporated into the Earth when the Solar System formed.
