Questions and answers regarding the Comecer Calibration Centre services, from the request for calibration to the use of the certificate issued.
If the answer you are looking for is not among the following, write to the Comecer Calibration Centre, filling-in the contact module.
The Comecer Calibration Centre performs calibration of personal passive dosimeters and measurement assemblies (instruments) of ionising radiation in the radioprotection ambit, quality controls and measurement of activity. (see Instruments section).
No, the Calibration Centre does not perform revisions or repairs on the instruments, but supplies the calibration factor that indicates the relation between the reference values and the values measured by the instrument.
First request an estimate for calibration. If you accept our offer you can send or personally deliver the instrument to the Comecer Calibration Centre.
The Table of reference contains all types of beams and sources that can be used for calibration in the Comecer Centre.
Certainly, instruments that measure the quantity of radioactivity can be calibrated at our Centre.
Yes, the Calibration Centre has many sources that can be used to calibrate contamination meters.
Yes, the Calibration Centre has liquid sources that can be used to calibrate dose calibrators.
As of today the materials used for protection from radiation must be in compliance with the IEC EN 61331 Standard. This Standard explains the methods of execution of the measurements for the determination of the equivalent in lead.
The controls that can be performed (usually by the Qualified Expert), are the following:
The frequency of calibration can be established by analysing the following parameters:
Currently the ISO Standards envision that the user must decide the frequency of controls. In the past for portable instruments used in radioprotection, the UNI 8143 Standard (1980) envisioned that the calibration controls were performed at least once a year.
The Calibration factor must be multiplied by the value measured by the instrument: in this way the correct value of the detection is obtained.
The Calibration factor corrects the measurement and takes the value read by the instrument to the reference unit of measurement (mGy or mGy/h); the Dimensionless calibration factor corrects the measurement without modifying the unit of measurement of the instrument.
It is the use who must establish the limits of use of the instrument and for any repairs. The Calibration Centre reserves the right to inform the operator if the instrument is not in compliance with the specifications envisioned by the manufacturer or is unusable for the purposes envisioned.
