Radiometric dating - Wikipedia

Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements. By "age" we mean the elapsed time from when the mineral specimen was formed. Radioactive elements "decay" (that is, change into other elements) by.

Radioactive Dating

A potassium-argon method of dating, developed in , measures the amount of 40 Ar arising from the 40 K decay and is compared to the amount of 40 K remaining in the rock. From the ratio, the time since the formation of the rock can be calculated. The age of our galaxy and earth also can be estimated using radioactive dating.

Radioactive Dating, BioNinja

If one knows the rate of radioactive decay of a parent radioisotope in a rock (the sand falling rate in the analogous hourglass “clock” of figure 2), and how much daughter isotope is in the rock today (the quantity of sand at the bottom), then the age of the rock is the time it has taken for the daughter isotope to accumulate in the rock by.

Assumptions of Radioactive Dating • Smilodon's Retreat

Radioactive Dating. Because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of the environment outside the nucleus save direct particle interactions with the nucleus, then radioactive samples continue to decay at a predictable rate and can be used as a clock.
