Low dose plastic optical fibre radiation dosimeter for clinical dosimetry applications

PMMA optical fibres offer the opportunity to monitor ionising radiation doses online and in real-time. The work presented here investigates the use of these fibres in clinical dosimetry applications. Tests to determine the sensitivity of the PMMA optical fibres at low radiation doses were carried out at the MD Anderson Cancer Center Orlando, Florida. The results demonstrate that PMMA optical fibres exhibit a quantifiable response to low doses (up to 12Gy) of radiation, similar to that received during radiation treatment.
