Multiline EPR signal of dried Morocco raisin irradiated with the dose of 0.5 kGy. Unirradiated raisin does not show any EPR signal. g0 corresponds to geometric centre of multi-component signal.

Results of the PSL (for hot peppers) and TL (for sweet peppers) examination of minerals isolated from the dried peppers
| Name of sample | TL intensity (150–250°C) | Glow ratio A/B | |
|---|---|---|---|
| Glow A | Glow B | ||
| Hot peppers | 107 664 | 2 446 361 | 0.437 |
| Sweet peppers | 8 271 517 | 9 420 144 | 0.878 |
[i] PSL, photoluminescence; TL, thermoluminescence.
Fig. 2
EPR signal of irradiated sample of matured hazel-nut shells harvested in Polish farms. Two satellite lines of isotropic triplets distanced by 6.0 mT assigned to cellulose radical are considered the evidence of radiation treatment. The central line of the cellulose triplet is superimposed by a strong native singlet and overgrows the frames of the figure.

EPR signal of chicken bone sample, irradiated with 0.5 kGy, assigned to a singlet of axial symmetry of 
ion radical.
