Calibration is the process of checking an instrument to ensure that it complies with the manufacturer's specification i.e., that it properly measures the radiation level to which it is exposed. This involves exposing the instrument to varying types and doses of radiation.
Calibration of a radiation measurement instrument is carried out by taking a reading of a precise and known quantity of radiation which is traceable to international standards. Readings are compared to manufacturer’s specifications to ensure the instrument is functioning correctly.
All businesses and practices which 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.
Under Irish law, radiation measurement instruments must be individually calibrated before first use and annually thereafter to ensure that they are in full working order. They should also be calibrated after any repair is carried out.
The EPA Calibration Service calibrates the most commonly used radiation measurement instruments in Ireland, namely:
Please contact the Calibration Service in advance to arrange a suitable date for calibration. Download the application form and send it to us with the instrument for calibration. An official purchase order number must be supplied.
You will be asked to supply contact details, delivery address for return of the instrument, and preferred payment method. You will also be asked to supply some details about the instrument(s) to be calibrated and your exact requirements.
Transportation of instruments to the EPA is the responsibility of the customer. The return of the calibrated instruments to customers is organised by the EPA.
An official purchase order must be provided in pdf, with the courier fee for the return of the instrument included. The courier fee will be added to all calibration quotes.
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.
For further information, please contact us directly at the EPA Calibration Service.
The instrument should be sent by courier in a suitable container, or personally delivered to:
EPA Office of Radiation Protection and Environmental Monitoring
EPA Calibration Service
|Telphone||(01) 268 0100|
|Opening hours||9.00 am to 5.00 pm|
If the instrument is sent to us by post, it should be suitably packaged to prevent damage during transportation.
It should also be prominently labelled with the words FRAGILE ELECTRONIC INSTRUMENT, or similar.
A calibration certificate is returned together with the calibrated instrument.
