Dosimetric quantities

The dosimetric quantities that have been developed are:

  • Absorbed dose to water (Gy) and Absorbed dose to water rate (Gy s-1) for γ photons
  • Absorbed dose to water (Gy) and Absorbed dose to water rate (Gy s-1) for electrons
  • Air Kerma (Gy) and Air Kerma rate (Gy s-1) for γ photons and X-radiation
  • Exposure (Cb kg-1 and R) and Exposure rate (Cb kg-1 s-1 and R s-1) for X-radiation
  • Dose Area Product (DAP) (Gy mm2)
  • Dose Length Product (DLP) (Gy mm)
  • Ambient dose equivalent H*(10) (Sv) and Ambient dose equivalent rate (Sv hr-1) for γ and X-radiation
  • Personal Dose Equivalent at depth 10 and 0.07 mm, Hp (10) (Sv) and Hp (0,07) (Sv)
  • Parameters for diagnostic radiology devices: High voltage (kV), electric charge (mAs), electric current (mA) and exposure time (ms) of an X ray beam lamp.

Reference instruments of high accuracy and quality are used for the development and maintenance of the above dosimetric quantities. These reference instruments are periodically calibrated in the following primary laboratories:

  • BIPM (Bureau International des Poids et Mesures France),
  • PTB (Physikalisch-Technische Bundesanstalt, Germany),
  • IAEA (International Atomic Energy Agency, Austria) and
  • NPL (National Physics Laboratory, England).

These instruments "transfer" the accuracy from the standard laboratory to EEAE calibration laboratory, which in turn transmits it to the user.
