Knowledge in radiation protection of operators in medical imaging in Bangui and Bimbo (Central Africa Republic)

摘要

X-rays, main source of exposure to ionizing radiation (IR) of human origin have a harmful role in genesis of malignant and cancerous diseases. The application of the principles of radiation protection by all staff using x-ray is a regulatory obligation. International Atomic Energy Agency (IAEA) recommends that all staff have to be trained with capabilities and competences checked up before performing specific task. A survey was conducted with personnel working under IR in Bangui and Bimbo radiodiagnosis establishments to assess their levels of knowledge in radiation protection. Among the respondents, 36.6% had a degree of senior technician in radiology and medical imaging, trained in radiation protection without renewal of knowledge. The level of knowledge of all staff, regardless of the profile and the establishment is very modest. Application of principle of justification of exams is not effective in all establishments. Quality control never took place in establishments, they lack anyone to refer in radiation protection and protection against X-ray equipment. Government and ANR must continue to work together for continuing education in radiation protection of the staff and for quality control.
