The mechanoelectret, field and corona-electret properties of micas and
mica papers are described. They include the electret potentials, the
density of electrical charges, the times of relaxation and the energy
of charge localization. The electret production mechanism is described
. The radiation sensitivity maximum for corona-electret TSD curves is
identified. Practical recommendations are given. (C) 1997 Elsevier Sci
