Investigation of LiF, Mg and Ti (TLD-100) Reproducibility

Investigation of LiF, Mg and Ti (TLD-100) Reproducibility

LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and t...
