Two Stegomastodon teeth (AL1 and AL2) from north-eastern Brazilian megafauna were studied by electron spin resonance (ESR) spectroscopy.
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.

In the European Union (EU) directives  clearly state that irradiated food as well as food containing irradiated ingredients (regardless of their percentage) must be labeled (the international food irradiation symbol, the radura, is shown above).
