“…ESR is used for dating minerals and rocks containing paramagnetic defects related to SiO 2 , cave deposits with defects in calcite, biocarbonate defects in fossils and sediments as shells, corals or molluscs, apatite related defects in bones, tooth enamels and dentine [1,4]. Human and animals bones and teeth are very suitable for dating [1,[5][6][7], for an estimation of absorbed dose of irradiation (like for Hiroshima A-bomb victims) [1,8,9] and for detection of irradiated foodstuffs containing bones or fish-bones [10].…”

“…Normalmente, os radicais livres são espécies transientes de duração bastante curta mas, no caso de matrizes secas como sementes, ossos e grãos o tempo de vida é suficiente para a detecção [6]. A partir de resultados de medidas com gordura e ossos de porco e boi, a RPE foi considerada como método capaz de identificar determinados grupos de alimentos irradiados.…”

“…Isto quer dizer que a mera presença de radicais livres não determina o tratamento pela irradiação, mas modificações específi-cas induzidas pela radiação nos radicais existentes [6,11]. Em outros casos, em alimentos in natura, pode-se encontrar metais ou radicais livres pela contaminação de resíduos de fertilizantes [4].…”

“…Sucrose is not the only sugar interesting from a dosimetric point of view. One can also apply EPR spectrometry for detection and control of irradiated sugar-containing foodstuffs [33][34][35][36][37][38][39][40][41][42]. Here, however, an additional complication arises.…”
