Espinosa, R.B. Gammage, K. Meyer, R.B. Wheeler, M. Salasky] A gross analysis is presented of alpha radiation from 241Am, 239Pu, 230Th, 244Cm, 238U and 237Np sources, using nuclear track detector (NTd) methods. The response of the NTD was measured at low and high alpha emission rates, fixed exposure times, and fixed quantity of total alpha particles for each of the different isotopes over a range of alpha energies. The distributions and statistics of the track densities were calculated. LANTRAK polycarbonate was selected at the NTD detector material. A one-step chemical etch in 6.25 NaOH at 60 oC for 16 hours was used. Twenty-four fields (0.91 mm2) on each detector were read using an automatic counting system. The results show the linearity and efficiency of the material for each alpha energy and the track diameter distribution relative to energy.
