[Thermo-luminescent dosimetry (author's transl)]
Insights
Paediatric radiology aims to minimize radiation dose using new techniques. Thermoluminescence dosimetry offers a suitable method for accurate radiation measurement in children, replacing older ionization chambers.
Area of Science:
- Medical Physics
- Radiological Sciences
Context:
- Paediatric radiology has focused on dose reduction since the 1950s.
- Accurate dosimetry in children has lagged due to measurement technique limitations.
- Ionization chambers were previously standard but less suitable for precise paediatric measurements.
Purpose:
- To highlight the effectiveness of thermoluminescence dosimetry (TLD) for paediatric radiation dose measurement.
- To advocate for the adoption of TLD in paediatric diagnostic imaging.
- To address the historical gap in paediatric radiation dosimetry studies.
Summary:
- Thermoluminescence dosimetry provides a superior method for measuring radiation doses in paediatric patients.
- This technique allows for more accurate assessment and control of radiation exposure in children undergoing radiological examinations.
- The shift from ionization chambers to TLD represents a significant advancement in ensuring patient safety.
Impact:
- Facilitates improved radiation safety protocols in paediatric radiology.
- Enables more precise dose monitoring, crucial for vulnerable young patients.
- Supports the ongoing development of best practices in paediatric medical imaging.
Abstract:
The development of paediatric radiology which began in the late 1950's has been characterised by the need to limit the dose of ionising radiation to which the child is subjected. The aim has been to keep radiation exposure as low as possible by the introduction of suitable techniques and by the development of new methods. It is therefore surprising that studies in dosimetry in the paediatric age range have only been carried out in recent years. One reason for this may have been the fact that a suitable technique of measurement was not available at the time. The introduction of solid state dosimetry based on thermo-luminescence, first into radiotherapy (1968) and subsequently into radiodiagnosis, has made it possible to abandon the previously widely used ionisation chamber (1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 14 and 14). The purpose of the present paper is to indicate the suitability of this form of dose measurement for paediatric radiological purposes and to stimulated its application in this field.
