Research Profile
Jethro completed his Bachelor of Science in 2009, majoring in physics and mathematics at the University of Canterbury.
Jethro's project involves the characterization of selected fluoroperovskite crystals as optically stimulated luminescence (OSL) dosimeters with the radiation qualities employed in radiotherapy. These materials are being investigated as remote fibre dosimeters, where the dosimeter is mounted at the distal end of an optical fibre and interrogated optically, a setup potentially well suited for in vivo dosimetry and scanning radiation detectors.
As fibre coupled dosimeters are unmatched in physical size one of the more promising applications envisaged is the measurement of radiation fields too small for conventional dosimeters. It is also possible to manufacture fibre dosimeters small enough to be accommodated by catheters and applicators for dose verification in brachytherapy.
