More detailed and more technical background information is given relating to this topic of the fifth call for proposals under the specific programme for standards, measurements and testing (SMT), 1994-1998. New research is needed aiming at the following points:

- Which fruits reveal irradiation specific ESR signals and which ones do not?
- Can ESR be used for the identification of irradiated sugar containing foodstuffs other than dried fruit, eg. chocolate?
- What is the reason for the different ESR spectra produced by various species of dried fruits as compared with other foodstuffs containing sugar?
- Is it possible to set up a list of fruits, which show specific ESR signals after irradiation?
- What is the reason for the different ESR spectra found for different fruits?
- Obviously different radicals were formed; what is the structure of these radicals?
- The relationship between structure of the ESR spectrum and composition of the sugars in the fruit has to be examined.

A time scale and expected result format are also described.
