  • Title: Spectrum file size optimization for EPR tooth dosimetry.
    Author: Romanyukha AA, Ivanov D, Schauer DA, Thomas JA, Swartz HM.
    Journal: Appl Radiat Isot; 2005 Feb; 62(2):197-200. PubMed ID: 15607448.
    Abstract:
    Spectral acquisition time is one of the limiting factors in electron paramagnetic resonance (EPR) retrospective biodosimetry in teeth. Acquisition times for one sample can be from 2 to 4h. This problem is even more acute for in vivo EPR measurements in L-band. Patients cannot be expected to remain stationary for these lengths of time. In order to overcome this limitation, we investigated the dependence of EPR dose measurements on the number of data points in an EPR spectrum. We have shown that this number could be reduced from 1024 to 256 (factor of 4 reduction in spectral acquisition time) at 5 mT magnetic field sweep without a loss of precision in the dose measurements.
