Abstract

Unirradiated ammonium tartrate (AT) samples do not exhibit any ESR signal. However, irradiation produces an unresolved singlet at g=2.0034±0.0006 with two shoulders at g₁=2.0093±0.0006 and g₂=2.0048±0.0006. The dose-response curve was found to increase linearly with the applied radiation doses in the range of 0.1-2.0 kGy and the slope of this curve was increased as the modulation amplitude increased. The activation energy value E_a=69.0±1.2 kJ/mol was calculated from Arrhenius plot for the radical species responsible from ESR spectrum of irradiated AT.
