The problems of argon loss can be overcome by using the argon—argon method. Generally a shorter half-life leads to a higher time resolution at the expense of timescale.

This involves the alpha decay of Sm to Nd with a half-life of 1. The radiometric decay series commonly used in radiometric dating of rocks are detailed in the following sections. K—Ar dating has therefore been widely used in dating rocks but there is a significant problem with the method, which is that the daughter isotope can escape from the rock by diffusion because it is a gas.

The amount of argon measured is therefore commonly less than the total amount produced by the radioactive decay of potassium. The choice of method of determination of the age of the rock is governed by its age and the abundance of the appropriate elements in minerals. No it is not true all rocks can be dated radiometrically. The half-life of this decay is The Swedish National Heritage Board. Detectors at the end of the tube record the number of charged particles of a particular atomic mass and provide a ratio of the isotopes present in a sample.
