ENGLISH ABSTRACT: Introduction - X-ray imaging is used to diagnose and follow up various conditions in neonates (i.e. pre-term babies and babies up to the age of 28 days). Chest anterior-posterior (AP) radiographs are used ...
During fluoroscopic bladder and bronchial examinations the radiation workers concerned are exposed to 90°-scattered photons. The effective energy expressed in mm Al was measured for these photons exited at tube potentials ...
A study of the rates of repeat radiography in two hospitals
in the Cape Peninsula was undertaken. The relationship
between these rates and the type of examination
as well as the contributing factors was established.
The ...
