ALARA study of teaching effectiveness on reducing radiation exposure

Area of Science:

• Medical Imaging and Radiation Oncology
• Occupational Health and Safety
• Nursing Education

Background:

• Endoscopic procedures pose risks of radiation exposure to healthcare professionals.
• Effective radiation safety training is crucial for minimizing occupational hazards.
• Measuring the impact of training on actual radiation exposure is essential for validating its effectiveness.

Purpose of the Study:

• To evaluate the efficacy of a radiation safety training program for endoscopy nurses and technicians.
• To assess the correlation between radiation safety knowledge and actual radiation exposure levels.
• To determine the long-term impact of the training on radiation film badge readings.

Main Methods:

• A cohort of 144 endoscopy nurses and technicians participated in the study.
• Participants underwent pre-instructional radiation safety knowledge testing.
• A radiation safety course was administered, followed by immediate and 6-month post-instructional testing.
• Radiation exposure was monitored using film badges at baseline, 1 month, and 6 months post-instruction.

Main Results:

• The radiation safety instruction significantly improved participants' knowledge.
• A slight reduction in radiation film badge readings was observed post-instruction.
• The decrease in radiation exposure levels was not statistically significant.

Conclusions:

• Radiation safety training is effective in enhancing knowledge among endoscopy personnel.
• While knowledge improved, the training did not lead to a statistically significant reduction in occupational radiation exposure.
• Further research may be needed to identify more impactful strategies for reducing radiation exposure in endoscopic settings.
