Many applications likehomeland security, radiation
protection, control of fissile material proliferation and other
require not only detection of radioactive materials, but also their
localization. We are presenting a directional detector based on an
array of semiconductor detectors capable to determine direction
where the radioactive source is placed.
Semiconductor single pad detectors are arranged into rows
and separated by a shielding material. Selection of the detectors
and shielding material depends on the type and energy of the
radiation desired to monitor (i.e. X-rays, gammas or neutrons).
Level of the signal, i.e. count rate, in each detector depends on the
angle of the incoming radiation. Analysis of the count rate in each
detector allows calculating angular position of the source.
A series of simulations and evaluating measurements of the
directional radiation detection principle is presented.
