WebDose Constants for seed sources. Dosimetry of I-125, Ir-192 and Pd-103: The dose rate constant Λ (cGy/U-hr) is defined as the dose rate to water at a distance of 1 cm on the transverse axis of a unit air kerma strength source in a water phantom. The constant includes the effects of source geometry, the spatial distribution of radioactivity ... http://www.icrpaedia.org/Dose_coefficient

Webext,zi is the dose conversion coefficient for external exposure defined as the ratio between the average activity concentration of radionuclide i in the reference media corresponding to the location z and the dose rate to organism b (µGy/h per Bq/kg fresh weight or Bq/L). The DCCs used correspond to those reported in ICRP (2008) [XII–1].
