Track densities (�) are measured as (x10 5 tr/cm 2 ); N is the number of tracks counted; �s = spontaneous track density; �i<br />
= induced track density, �d = track density of the dosimeter glass (CN5); P� 2 is the probability to obtain the chi-square<br />
value for n degree of freedom (n is the number of crystals –1). AD = Durango apatite, AF = Fish Canyon Tuff apatite.<br />
