These crystalline solids are constantly subjected to ionizing radiation from their environment, which causes some energized electrons to become trapped in defects in the molecular crystal structure.

Mineral separations are performed by standard techniques using heavy liquids and hydrofluoric acid (HF) to digest non-quartz minerals and etch the outer 10–20 μm of quartz grains, which are affected by alpha radiation.

in OSB mills, alone or alternating with OSB either with a conventional species such as trembling aspen (Populus tremuloides), to which the OSB industry is already well adapted (although raw material availability is limited), or other available species such as paper birch (Betula papyrifera), which is currently under-utilized across Canada.

Training, to help its clients and others to stay ahead in business by up-skilling their staff, delivering NVQs in customer service, conflict resolution, manual handling, supervisory and other key management skills.

Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired.

The major source of error in establishing dates from thermoluminescence is a consequence of inaccurate measurements of the radiation acting on a specimen.
