摘要：
A novel method of determining two-dimensional (2-D) dose distributions was developed using in-house produced large-area thermoluminescent (TL) detectors based on LiF, read with a newly developed planar large-area TL reader equipped with a CCD camera. The detectors were developed by attaching, pressing and sintering thermoluminescent LiF:Mg,Ti or LiF:Mg,Cu,P powder on Al foil of 0.3 mm thickness. The detectors, of active area of a few square centimeters, read out using the large-area TL reader, were successfully used to map the 2-D dose distribution around an alpha source Am-241, a Ra-226 needle source and a Ru-106 ophthalmic applicator.
