Ru-106 ophthalmic applicators

NPL has developed a calibration service for ophthalmic applicators. The calibration is performed by irradiating thin alanine pellets placed on a Perspex phantom.

  • Calibration of Ru-106 and Sr-90 curved and planar applicators traceable to NPL's primary standard for absorbed dose to water (graphite calorimeter ) via alanine dosimetry
  • Calibration in terms of absorbed dose rate to water, normally at 0 mm and 2 mm depth
  • Uncertainty of calibration is estimated to be ± 7 % (k=2)
  • Service is available on demand
  • Turnaround time is approximately two weeks
