<p>A method for detecting and correcting for isotope burn-in during long-term neutron dosimetry exposure preferably with duplicate solid state track recorder fissionable deposits, including a first, fissionable deposit of lower mass to quantify the number of fissions occuring during the exposure, and a second deposit of higher mass to quantify the number of atoms of for instance <2><3><9>Pu by alpha counting. With only one solid state track recorder fissionable deposit the resulting higher track densities are counted with a scanning electron microscope. This method is also applicable to other burn-in interferences, e.g., <2><3><3>U in <2><3><2>Th or <2><3><8>Pu in <2><3><7>Np.</p> |
