  • Page 21: System Parameters Menu

    Parameters MENU -- SYSTEM PARAMETERS MENU This menu allows critical system operational parameters or data to be modified by an authorized manager. This menu is password protected by the highest (manager) level password. IMPORTANT NOTE: The Dose Rate functions, Set Unattenuated (High) Rate and Set Attenuated (Low) Rate are the calibrated dose rates of the CS-137 source for the high and low attenuation settings.
  • Page 22 Traveling dose is given by the dose rate multiplied by the element travel time in front of the beam. Knowing the timing for one step is 0.002s, one way traveling time is: 18.3 x 0.002s = 0.0366s Total time for round trip is: 0.0366s x 2 = 0.0732s Example: If the dose LOW is 0.0281mSv/s and dose HIGH is 0.281mR/s, LOW traveling dose is:...
  • Page 23 This requires the TLD Reader to be calibrated relative to the PSDL or SSDL and the Irradiator exposure adjusted to this using the same reference TLDs. Please discuss with Panasonic in detail. For Reference - Automatic Internal Calculation of Source Decay: = ( Initial Dose Rate ) e - ( 0.693 t / T )
  • Page 24: Individual Dose Setting Menu
