SUMMARY
The calibration of ion flow chambers requires specific procedures and materials, particularly a Cs-137 sealed source or another long-lived nuclide for accurate calibration. Understanding the relationship between activity measured in Bq/m3 and dose rate in mSv/h is crucial, as it varies based on the nuclide's energy. Proper training is essential due to the hazards associated with handling radioactive materials. Additionally, knowledge of gamma constants and exposure constants is necessary for effective calibration and conversion.
