Abstract
ABSTRACT
Background: The radiographers working in radiation wards need to have
an adequate knowledge about the risks and preventive measures of radiation
exposure to protect themselves from health hazards of ionizing radiation
Aim: The study amid to evaluate the effect of guidelines for radiographers
on ionizing radiation hazards. Design: A quasi-experimental design was
conducted to achieve the study. Sample: A convenient sample of all
radiographers was choosen equal (95radiographers). Setting: The study was
conducted at four hospitals affiliated to El Mansoura general hospitals (Old
general hospital, Eldawley General hospital, Chest hospital and Fever
hospital) Tools: Three tools were used for data collection. TOOL (I): A
structured Interview Questionnaire consisted of four parts,
part(1)demographic characteristic, part(2) Occupational characteristics of
radiographers, part(3) past& present medical history, part(4)Radiographers
knowledge about the ionizing radiation Tool (II) Radiographers practices.
Tool (III) Observational Checklist for Environmental Safety. Results: The
study results revealed that 65% of studied sample had poor knowledge at
pre guidelines, while improved 85% of them had good knowledge at post
guidelines with highly statistically significant, 85% of the studied sample
had unsatisfactory practices about ionizing radiation hazards at pre
guidelines, while improved 80% of them had satisfactory practices about
ionizing radiation hazards at post guidelines with highly statistically
significant. Conclusion: The study proved that there was an improvement
of radiographer’s knowledge and practice about ionizing radiation hazards
at post than pre guidelines, Recommendations: continues health
educational programs to all radiographers in hospitals to improve their
knowledge and practice about ionizing radiation hazards.
