Passive dosimeters

The passive dosimeters are devices that detect the doses of radiation that staff may have absorbed while performing their job.

Use ambits

The passive dosimeters are used especially in the medical and industrial ambit, their use is indicated wherever staff is exposed to a radioactive risk. The dosimeters are personal as they are assigned to a specific person and must not be given to anyone else.

Calibration and certification

The dosimeters are read with variable frequency (every 3, 6 or 12 months) by the company distributing them. To verify the efficiency of the reading, these companies must irradiate some dosimeters with known values of doses in order to calibrate their instruments.

The Comecer Calibration Centre carries out this service in agreement with that envisioned by the Accredia procedures.

The passive dosimeters can be irradiated using X and γ radiations in air on ISO phantoms.

The Comecer Calibration Centre carries out this service issuing a Accredia Certificate in compliance with that envisioned by the quantities accredited by Accredia.

Recommended times

Comecer recommends periodic check of the instruments used to determine the dose at the dosimeter at least once a year using the methods described above.
