NOTES ON PHYSICIST MEASUREMENTS
V.1. SUGGESTED AUDIT EQUIPMENT KIT
It can be difficult for an auditor to bring a full set of equipment and
phantoms, owing to its size and weight, to assist in an audit. However, as a
minimum, a calibrated dosimeter is highly recommended, to allow a cross-check
of the calibration instruments at the host facility.
V.1.1.
Instruments
The following instuments can be useful for an audit:
(a) An electrometer;
(b) Detectors (calibrated) for:
—Entrance beam,
—Scatter radiation,
—CT equipment,
—Mammography equipment,
—KAP meter;
(c) A kVp timer meter;
(d) Sensitometry equipment and a densitometer;
(e) A photometer;
(f) Aluminium foils for the main X ray and mammography energies;
(g) A magnifying glass (×4);
(h) Miscellaneous items, such as a tape measure and lead markers.
V.1.2.
Phantoms
The following phantoms can be useful for an audit:
(a) A CDRH (Center for Devices and Radiological Health) chest phantom [32];
(b) An ANSI (American National Standards Institute) abdomenal phantom [32];
(c) For mammography:
(i) An ACR (American College of Radiology) mammography phantom
(suggested as a possibility in an IAEA mammography QA protocol
[34] and very common worldwide);
(ii) Sheet(s) of 45 mm total thickness of polymethyl-methacrylate
(PMMA) [34];
