SSDL Calibration Services


​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 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).

Required Documents

​The customer must email the SSDL Team with the calibration request and the user manual or the technical specifications of the instrument(s) to be calibrated. The email must be sent to:

Time Frame

Once the SSDL Team has approved your calibration request, the SSDL Team will contact you in order to schedule the delivery of your instrument(s). The SSDL Team will also inform you of the date of calibration of your instrument.

For ion chamber calibration, please be informed that the secondary standards dosimetry laboratory will need to receive your chamber at least four days prior to calibration for acclimatisation of the laboratory’s environmental conditions (i.e. temperature and humidity). 

The calibration itself takes half a day for an ion chamber and a survey meter; the irradiation of passive dosimeters can take up to one day subject to the number of dosimeters and to the doses required.

How To Apply

In order to deliver a calibration service, FANR’s secondary standards dosimetry laboratory needs the calibration request form that contains all the relevant information:

  • Administrative details: organisation name, contact person, e-mail, mobile number, etc.
  • Technical details: required quantity, dose or dose rate, etc.

Once the SSDL Team approves the calibration request and you agree on the calibration schedule, you can send your instrument(s) by express courier to FANR’s secondary standards dosimetry laboratory or to take it there yourself directly.

The address of the FANR’s secondary standards dosimetry laboratory is:
Khalifa University – Al Zafranah
Abu Dhabi, UAE
