Abstract
The evaluation of the quality of radiographic practices in diagnostic radiology
Departments is very important for reduction of radiation doses to patient, personnel
and members of the public. To this end, a number of quality control test were
performed in eight hospitals in Zaria and Sabon Gari Local Government Areas of
Kaduna State. The test is test on structural shielding, Reject analysis, test for exposure
timer setting, test for light beam misalignment, x-ray beam misalignment and
darkroom safe light test.
The result of the tests indicates that the protective barrier was sufficient to shield
for the primary radiation in all the hospitals, while two hospitals have inadequate
protection of secondary radiation for their darkrooms. The exposure time setting
of all the hospitals were working within the tolerable limit. There is mismatch of
alignment of light beam with radiation beam in all x-ray machines. X-ray beam
alignment test gives satisfactory result except one hospital which no light beam
diaphragm. The safe-light tested were in good conditions. The value of K and in was
determined for use in estimating dose that would be received by patient in a particular
examination at particular exposure parameter setting. The values for k were 0.189,
0.176, 10.0, 1.0128, and 0.00036 while the values for n were 1.752, 3.109, 2.22, 2.95
and 4.66 for Hosp. A Rm I and II, Hosp. E, G and H respectively. There are no
qualified x-ray personnel except in one hospital. There is a poor darkroom procedure in all the hospitals
