Calibration facility for radiological calibration with isotope sources or x-ray tubes

  • Turn-key project possible
  • Newest technology in mechanics, dosimetry and software
  • Calibration knowledge can be shared

The calibration facility is designed for fast and accurate radiological calibration of radiation detection equipment such as chambers, detectors and dosemeters. It can be used with an isotope source or x-ray tube depending on the requested radiation qualities to be calibrated. The wide product range allows an installation of the required equipment of a complete radiological calibration laboratory.A complete turn-key project can be offered with  isotope source or filter wheel with filters, shutter, tube support, calibration software and accessories such as LASER ALIGNMENT System, LABGUARD Surveillance System, Radiation Surveillance System and Camera Monitoring System. Customized project management can include a complete calibration bench project including user training for calibration process according to the requirements of secondary standard dosimetry laboratories (SSDL), where the customer can profit from the experience of the PTW's  SSDL, doing more than 12000 calibrations per year.

Safety technology can be integrated and tested by PTW in the installation phase. Independent of that, responsibility for ensuring compliance with applicable national legal safety regulations is that of the operator of the calibration facility.
