Calibration Measurement

The accurate measurement of ionising radiation is central to ensuring its safe and effective use and therefore the instruments used for this surveillance need to be regularly calibrated.

The EPA provides a calibration measurement service which is accredited by the Irish National Accreditation Board to ISO 17025.

Information for customers on arranging instrument calibration is given in the document Calibration Service - Guidance for Customers.

What is calibration?

Calibration is the process of checking an instrument to ensure that it complies with the manufacturer's specification. This involves exposing the instrument to varying types and doses of radiation.

Who is responsible for calibration?

All businesses and practices which are licensed to use sources of ionising radiation are obliged by law (S.I. 125 of 2000) to ensure measuring instruments are accurately calibrated. They must also be regularly checked to ensure that they are serviceable, and that they are being correctly used.

How frequently does my instrument need calibration?

Under Irish legislation, (S.I. 125 of 2000) radiation measuring instruments must be calibrated before first use and annually thereafter to ensure that they are in full working order.

Important notes:

Transportation of instruments to and from the EPA is the responsibility of the customer.  However, we can organise couriers to return instruments to our customers.

An official order number must be provided.

Please be aware that slots fill in quickly and should we have no available dates to accommodate your request, there are alternative labs that provide the same service.
