“…They are going in two directions: one is to search for more sensitive dosimetric materials and the second is to increase the accuracy of EPR quantitative measurements. Regarding the first direction, very promising results on sugar (sucrose) (Nakajima, 1988;Generalova et al, 1993;Flores et al, 2000), ammonium tartrate (Olsson et al, 1999;Olsson et al, 2000), dithionates (Bogushevich et al, 1996;Bogushevich and Ugolev, 2000;Lund et al, 2002) and formates (Lund et al, 2002;Vestad et al, 2003;Gustafsson et al, 2004) as radiation dosimeters have been published.…”
