A new method for the measurement of the mean etch-able fission track length and of extremely high fission track densities in minerals
In the present study a new and relatively simple method has been developed to measure the ratio of thermally reduced track length to unaffected track length ls/li. The method consists of counting track densities on different parallel planes cut from a single apatite sample, instead of measuring track lengths of a single surface plane; thus the desired ratio of lengths can be derived from ratios of track densities only. This method has been applied to samples of Durango apatite, yielding an averaged ratio of =1.14±0.06. The result is in good agreement with values we obtained by other independent methods of 1.12±0.05 and 1.13 ±0.05, respectively.
The present method, in addition, can also be used to determine extremely high fission track densities which otherwise would be too high for optical counting.
