Dosimetry for those subjected to radiation imaging as part of an imaging
research protocol is an essential component of clinical radiological research
activities.
Dosimetry methods used to estimate foetal dose should be documented.
5.1.5.3. Occupational dosimetry
Although routine occupational monitoring is typically the responsibility of
the RPO, certain situations may require additional personnel monitoring. This
may be a specialized process under the supervision of the medical physicist. This
includes additional personal monitoring for interventional fluoroscopy
examinations, monitoring of pregnant staff, and monitoring incidents of
accidental personnel exposures.
5.1.6. Instrumentation and calibration
The QA radiographer(s) and medical physicist should have access to
appropriate calibrated instrumentation, phantoms and other test equipment to
perform measurements and testing.
In order to ensure the accuracy of dosimetry and QC measurements, the
instruments used for testing must be calibrated at regular intervals against
accepted standards. The use of an accepted field cross-checking methodology is
encouraged as a cost effective way of maintaining acceptable dosimetry
standards. The facility should have a calibration policy and a record of equipment
calibration and equipment cross-checks.
5.2. THE AUDIT PROGRAMME
Annex III contains checklists for the following equipment-specific areas to
assist the auditor in reviewing radiation protection, as well as the general safety
and QC practices of the facility:
—Plain radiography;
—Fluoroscopy and image guided interventional procedures;
—Mammography;
—Computed tomography;
—Dental radiography;
—Ultrasonography;
—Magnetic resonance imaging;
—Screen–film systems and cassettes;
