Primary standards and traceable measurement methods for X-ray emitting electronic brachytherapy devices
Annotation in Czech
The overall goal of this project is to carry out pre-normative research on eBT to simplify and harmonise eBT dosimetric procedures and provide metrological input to standardisation bodies. The specific objectives are: 1. To establish primary standards for the absorbed dose rate to water for eBT devices at 1 cm depth of water for internal radiotherapy. To evaluate currently used transfer instruments and corresponding measurement procedures and to establish simple and robust tools for dissemination of the absorbed dose rate to water to clinical practice. 2. To establish a dosimetric methodology for superficial eBT aligned with or similar to the recommendations for superficial (skin) external radiotherapy given in International Atomic Energy Agency - Technical Reports Series (IAEA-TRS) 398, Deutsches Institut für Normung (DIN) 6809-4, Nederlandse Commissie voor Stralingsdosimetrie (NCS)-10 and Institute of Physics and Engineering in Medicine (IPEM). The target uncertainty for the conversion of dose at the surface (i.e. 70 μm) to dose at 1 cm depth is 5 %. 3. To characterise detectors and measurement instruments suitable for the determination of 3D dose distributions in water by eBT devices. To develop a standardised traceable calibration process for these detectors, allowing a reduction in the uncertainties in dose, dose distribution and dose-effect-relation to a level recommended in IAEA Human Health Report No 31. The aim is to achieve uncertainties (k = 1) for the calibration coefficients of not more than: 1 % - 2 % (NMIs) and EMPIR Page 7 of 45 18NRM02 PRISM-eBT Annex 1 v1.0 2 % - 3 % (clinic) for the scintillation detectors and for the small volume ionisation chambers, 3.5 % for the gel dosimeter and 2.5 % for the alanine pellets.

Project results evaluation
Following the condition that the candidate of financial contribution was evaluated and afterwards selected by international provider in accordance with the rules of the program the Ministry of Education, Youth ans Sports does not realize the evaluation of project results. The project is evaluated only after its approval by an international provider.
