Calibration is the measurement of the gap between a reference point as determined by the secondary standards dosimetry laboratory and the customer’s instrument. This gap is called the calibration factor and it is reported in a calibration certificate.
Calibration is essential to ensure that accurately known doses are delivered to patients undergoing diagnosis and therapy, and that radiation measurement instruments used throughout the UAE provide the expected degree of accuracy to support radiation protection.
The secondary standards dosimetry laboratory’s calibration services are accredited by the Emirates National Accreditation System (ENAS) and based on the ISO/IEC 17025:2017 Standard on the General Requirements for the Competence of Testing and Calibration Laboratories. FANR’s secondary standards dosimetry laboratory is accredited since December 2018.
FANR’s secondary standards dosimetry laboratory (SSDL) offers calibration services to the users of radiation measurement instruments. These calibration services are ISO 17025 accredited.
These services are:
- Calibration of survey meters using a Caesium-137 reference source to an ambient dose equivalent rate ("H" ^"*" "(10)" ) ̇ between 5 µSv/h and 20 mSv/h
- Calibration of ion chambers using a Caesium-137 reference source to an air kerma dose rate between 5 µGy/h and 15 mGy/h
- Irradiation [for calibration purposes] of passive dosimeters such as thermoluminescent dosimeters using a Caesium-137 reference source to a personal dose equivalent Hp(10) between 0.5 mSv and 10 mSv
In order to request the calibration services from the secondary standards dosimetry laboratory, you need to fill in the relevant form:
You must fill in one form for each instrument that you wish to calibrate.
Once complete, please email the form(s) to
firstname.lastname@example.org and the SSDL Team from the Radiation Safety Department will get back to you to set a schedule for the calibration of your instrument(s).
