ABSTRACT
Radiation doses received by patients during chest x-ray examinations were measured at the LadokeAkintola University of Technology Teaching Hospital, Osogbo on two different machines. Absorbed doses from full-size radiography were found to be within the acceptable limits for the posterior-anterior (P.A) view in adult and in children. The KV range for the two categories of patients, i.e. the adult and older children were recorded on the two generator types used, i.e. Phillips and Neo Diagnomax. The mean skin-entry doses of the patients x-rayed on the two generator types were obtained to be 64.18mrad and 61.46mrad for adult and children respectively on Philips generator, and 65.08mrad and 61.20mrad for adult and children respectively on Neo-Diagnomax.
