Thermoluminescent dosimetry (TLD) for megavoltage electron beam energy determination
Megavoltage electron beams are used in many institutions for the treatment of superficial malignant diseases. Accurate dosimetry of electron beams is a fundamental requirement for patient safety. To ensure this, national and international regulatory bodies conduct electron dosimetry audits utilising thermoluminescent dosimeters such as LiF:Mg, Ti (TLD100). TLD100 has been shown to exhibit energy dependence which can introduce errors in dosimetry. In this study commercially available TL materials have been used for a practical method developed to ascertain electron beam energy. This method could be applied in these dosimetry audits to reduce inaccuracies due to energy dependence of TLD100.
