Chapter 5: Calibration at the SSDL and Hospital Level
5.1. Establishment of standards for photon and intravascular sources
5.1.1. Traceability in calibrations at SSDLs
The recommended detector is an appropriately calibrated well type chamber.
The preferred traceability method is to have the well type chamber calibrated
against the primary standard at the PSDL. Calibrations at an ADCL or the
IAEA Dosimetry Laboratory can serve as an alternative. This calibration
should be carried out for each radionuclide and source type to be used.
5.1.2. Traceability in calibrations at hospitals
It is recommended that for brachytherapy sources be calibrated with an
appropriately calibrated well type chamber. For traceability, the well type
chamber should be calibrated at the SSDL (or ADCL).
