These instruments, used to measure ionising radiation, can have an integrated sensor or be composed by electronics (electrometer), which can be connected to various external probes.
The various types of probes can be used inside the whole-body radiation meters and externally.
The types of probes most commonly used in the ionising radiation measuring sector are called as follows:
The measurement assemblies are used in various fields, from medicine to industry, in general, wherever it is necessary to measure ionising radiation.
The Comecer Calibration Centre calibrates the instruments stated above using reference beams X of the radioactive sources in compliance with ISO 4037, BIPM 1972, IEC 61267 Standards.
The verification of the instrument takes place with the issue of the calibration certificate, which states the corrective factor to apply to the instrument.
If a clear document relative to the frequency of calibration has not yet been issued, Comecer recommends yearly or every two years if the instrument is not used often (not more than twice a month) or if similar instruments are owned, in a way to calibrate them alternately.
