  Background: The use of in vivo dosimetry with thermolumiscent dosimeters (TLDs) as a veritable means of quality control in conventional radiotherapy procedures was determined in this work. Aim: The objective of this study was to determine the role of in vivo dosimetry with thermoluminescent dosimeters (TLDs) as part of quality control and audit in conventional radiotherapy procedures delivered with CoâÃ?Â?Ã?Â?60 teletherapy machine. Subjects and Methods: FiftyâÃ?Â?Ã?Â?seven patients with cancers of the breast, pelvis, head and neck were admitted for this study. TLD system at the Radiation Monitoring and Protection Centre, Lagos State University, Ojo, LagosâÃ?Â?Ã?Â?Nigeria was used for the in vivo entrance dose readings. All patients were treated with CoâÃ?Â?Ã?Â?60 (T780c) teletherapy machine at 80 cm source to surface distance located at Eko Hospitals, Lagos. T.. Read More»
