Understanding Neutron Radiography Post Exam Reading VIII-Part 2a of 2A

PART 7. Semiconductors
Certain semiconductor crystals, when exposed to ionizing radiation, become
conductors and may be used as radiation detectors. Semiconductors are
most often used for low level spectroscopic measurements of alpha particles,
beta particles and gamma rays in laboratory settings and in X-ray diffraction
equipment (Table 5). The most widely used semiconductor devices are
diffused p-n junction, surface barrier and lithium drifted detectors.
Semiconductor detectors have found their broadest application in the field of
spectroscopy, although lithium drifted detectors are also being used for
gamma ray detection.
