A method for determining alpha-particle energy using CR-39 detector by utilizing matrix of energy, equation was described. The matrix was composed from two axes; the track minor axis (m) and diameter of etched out track end (d) axis of some selected elliptical tracks. The energy E in (m, d) coordinate was approximated by matrix of energy equations given by: E-k= Sigma(2)(i) j=0(-alpha)jd(i)m(k)(j)(,) which was identified using two different approaches. First, i and j were treated as power exponents for d and m. The adjusting parameters values a(ij) were obtained and the energy of a given track was deduced directly from it. Second, i and j were treated as indices of some chosen tracks that were fitted to obtain iso-energy curves that were superimposed on m-d scatter plot as calibration curves. The energy between any two successive iso-energy curves in this case was assumed varied linearly with d for a given m. The energy matrix in both cases was solved numerically. Results of the two approaches were compared.
