HDR 1000 Plus Well Chamber

Global standard for independently verifying prescribed
brachytherapy patient dose.

Confidence in Brachytherapy Source Calibration

  • Validated in over 50 scientific presentations and used by primary and secondary radiation standards laboratories worldwide.
  • The HDR 1000 Plus Well Chamber is an air-communicating chamber, so there is no inaccuracy due to an undetected gas leak as in a pressurized chamber.
  • Ideal for LDR and HDR brachytherapy.

Why Perform Independent Verification?

  • AAPM TG-56, TG-40 and TRS-398 recommend independent verification of source strengths.

  • Without independent calibration, centers in the U.S. may be forgoing reimbursement income.
