X-ray protection in pediatric radiology with special view on respiratory tract

Background: There is permanently growing demand in diagnostic radiological procedures in pediatrics. Important issue is to know precisely effects of dose radiation in children. Objective was to investigate effect of low dose radiation during X-ray examination of chest in children. Methods X-ray of chest was eximinated in patients and phantoms. The influence of low doses of radiation on chest and other organs, as well as effect of working method and human factor were analysed. Measurements were done with termoluminiscent dosimeters (TL) and radiophotoluminiscent dosimeters (RPL) adopted to age of children. Babies and small children were exposed in baby-fix and rotation chair, and older children stand in front of camera. The doses were measured in and on phantom (size of 3 years old child) too.The doses were compared with those of patients. Also, were investigated potential DNA damage. Results: Mean value X-ray dose in primary beam on chest x-ray in patients was 0.26 mSv ± 0.11mSv and in phantom 0.66 ± 0.17 mSv. Correlation was found between doses in primary beam and DNA damage. We found corelation between working method of technicans and X-ray doses too. Conclusion. Our long term work shows importance of permanent dosimetry in X-ray diagnostics in children. Continuous eduaction and good teamwork for dose reduction to minimize the potential damage is necessary to maintain the optimal benefit for patients especially children and medical staff too.
