Feasibility of PRESAGE®-IV dosimetry: Each point on the plot corresponds to PRESAGE® 1.5% o-MeO-DEA formulation material in two forms (in optical cuvettes (ΔOD/cm) and PRESAGE®-IV dosimeters (ΔOD/0.4 cm)) irradiated to the same dose and the change in OD measured by spectrophotometry. The change in optical density of the dosimeters was multiplied by a factor of 1/0.4 cm to account for the difference in path length between the dosimeters and cuvettes.
