This is the first book covering an interdisciplinary field between microwave spectroscopy of electron paramagnetic resonance (EPR) or electron spin resonance (ESR) and chronology science, radiation dosimetry and ESR (EPR) imaging in material sciences.

The main object is to determine the elapsed time with ESR from forensic medicine to the age and radiation dose in earth and space science.

The main object is to determine the elapsed time with ESR from forensic medicine to the age and radiation dose in earth and space science.

This book is written primarily for earth scientists as well as for archaeologists and for physicists and chemists interested in new applications of the method.

By increasing an external magnetic field, the gap between the energy states is widened until it matches the energy of the microwaves, as represented by the double arrow in the diagram above.

At this point the unpaired electrons can move between their two spin states.

EPR spectroscopy is particularly useful for studying metal complexes or organic radicals.

EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944,.

IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards by giving you access to standards from over 370 standards developing organizations (SDOs).

FEATURES & BENEFITS This is the first book covering an interdisciplinary field between microwave spectroscopy of electron paramagnetic resonance (EPR) or electron spin resonance (ESR) and chronology science, radiation dosimetry and ESR (EPR) imaging in material sciences.

The stability of the experimental conditions is ensured by: (i) a Thermo Flex3500 chiller connected to the ESR spectrometer, which controls and precisely stabilizes the temperature ( /- 0.1ยบ) of the water cooling the magnets, and (ii) an air conditioning system regulating the temperature of the room.

Worldwide, it is estimated that more than 500,000 tons of food and dietary supplements are treated with radiation with spices and vegetable seasonings making up the majority.

In practice, it is usually the frequency that is kept fixed.
