Disadvantages include the loss <strong>of</strong> information after readout and lack <strong>of</strong><br />

information about the incident radiation energy.<br />

Both gamma photons and neutrons produce ionization indirectly. Gamma<br />

photons interact with matter, releasing electrons that in turn cause ionization.<br />

Lithium fluoride undergoes interactions with gamma photons and is therefore<br />

used in gamma dosimetry.<br />

Slow neutrons require the presence <strong>of</strong> the lithium fluoride enriched with<br />

lithium-6 for detection <strong>of</strong> the (n, α) nuclear reaction.<br />
