Calibration services offered by the EPA

How to apply for our calibration services

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

See our Calibration Terms & Conditions document for further information.

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 that are licensed to use sources of ionising radiation are obliged by law 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, radiation measuring instruments must be calibrated before first use and annually thereafter to ensure that they are in full working order.

Calibration services offered by the EPA

Dose rate meters - Dose rate meters are used to measure radiation levels in a specific environment. They can measure both natural background radiation and man-made radiation.
Surface contamination monitors - Surface contamination monitors are typically used to detect radioactive spillage on work benches.
Personal monitors and alarms - Personal monitors and alarms are used to measure the radiation dose received by an individual.
