 Standard Dosimetric Installations for Gamma Radiation and Calibration Benchs
CALIBRATION MECHANICAL BENCH AT-02
 
High quality calibrations in the field of gamma radiation and x-ray radiotherapy and metrology.
 

Features:

  • Cooperation with gamma therapeutic units as AGAT-S, UPGD and their modifications
  • Positioning simultaneously up to 3 ionizing chambers and other dosimetry instruments on moving tables with different degrees of freedom, fixed on movable platform
  • High accuracy of ionizing chambers' fixation along radiation beam axis using high resolution optical devices
  • Simultaneous positioning up to 3 chambers on movable platform, overall water phantom of 300x300x300 mm, optical and laser system of visual positioning
  • Turnkey bench

Applications:


  • Ionizing radiation metrology
  • Laboratories to research, adjust and serialize dosimetry equipment
  • Metrology laboratories to graduate and verify dosimetry equipment
  • Second standard dosimetry laboratory (SSDL)
Calibration bench AT-02 provides positioning of ionizing chambers and other dosimetry instruments in collimated beam of x-ray and gamma radiation. Positioning is performed by operator's hand:
  • Positioning moving platform along radiation beam axis;
  • Positioning two moving tables (movable platforms) by precision guides perpendicularly radiation beam axis on moving platform;
  • Positioning three moving tables by precision guides on movable platform along radiation beam axis.
Supports to mount ionizing chambers of clinical dosimeters and water phantom (on second table) to measure absorbed dose rate are on moving tables. Moving table with water phantom could rotate on vertical axis. Lifting table to place different dimensional instruments can be placed instead of the water phantom. To pose ionizing chambers in necessary position and define their coordinates along radiation beam axis use laser device and measurement scale. If it is necessary use optical system (the level) to pose accurately ionizing chambers. The level and laser device are placed on moving table of bench platform, and measurement scale is mount on radiation bin wall parallel to radiation beam axis.

Additional informations:

Complete set: bench foundation with cylinder-shaped guides, moving platform, laser device for alignment, laser device and scale on radiation bin wall to define coordinates of equipment to verify, supports to mount ionizing chambers, rotating table for phantom, Manual.
Optional complete set by additional order: TV monitoring system of instruments' reading on the platform, optical device (the level) to pose accurately equipment to verify, lifting table, TV monitoring system (video camera, video monitor, cable).
