https://doi.org/10.1351/goldbook.I03190
A
radiation detector
which employs an electric field for the
collection
at the electrodes of charges associated with the
ions
produced in the sensitive volume by
ionizing radiation
, without charge multiplication. The solid
angle
(2Π, 4π ) subtended when using the detector, is sometimes specified.
