The age can be determined directly without estimating the equivalent dose (ED).
Age of substance can be determined by measuring the dosage of radiation since the time of its formation.
Electron spin resonance dating can be described as trapped charge dating.
Radioactivity causes negatively charged electrons to move from a ground state, the valence band, to a higher energy level at the conduction band.

As well as being useful for ESR dating, mollusks often present interesting problems in dosimetry. Extensive comparison dating is available for the deposits, using, for example, uranium series disequilibrium and amino acid racemization.
A number of molluskan species have been dated successfully by ESR. In addition, the work compares several proposed methodologies for determining the accumulated radiation dosage by ESR.
This work will discuss results on a previously unstudied genus, , using samples approx.
A new field, Quantum Geophysics, is expected in the interdisciplinary field between geoscience and the physics of defects.
An interdisciplinary research program of electron spin resonance (ESR) dating that detects cumulative radiation effects in natural minerals (Ca COO) and fossils has progressed considerably in these two decades.
