DESCRIPTION:Speakers: Nicholas Ade (None)\nAlthough diamond has been studi
 ed for dosimetry principally due to its near tissue-equivalence\, its use 
 in both low-energy X-rays and high-energy electron beams has not been repo
 rted. This report is based on dosimetric studies of a synthetic diamond pr
 obe when subjected to diagnostic mammography X-ray photons and megavoltage
  electron therapy beams. The probe\, constructed using entirely tissue-equ
 ivalent Perspex body was configured for radiation dose measurement in eith
 er ‘edge-on’ or ‘flat-on’ exposure geometry without having first\,
  to re-orientate the diamond within the body of the detector\, and it was 
 designed to be compatible with commercial electrometer systems. The radiat
 ion response of the diamond tested showed negligible energy dependence\; i
 ts minimal background signal\, high sensitivity (547.52 nC Gy-1mm-3) and s
 uitability for measurements in small radiation fields of steep dose gradie
 nts due to its small size make it suitable for clinical dosimetry. The pre
 sented probe has the potential advantage of replacing conventional radiati
 on dosimeters.\n\nhttps://events.saip.org.za/event/7/contributions/5149/
