The surface brachytherapy Task Group report number 253 discusses the common treatment modalities and applicators typically used to treat lesions on the body surface. Details of commissioning and calibration of the applicators and systems are discussed and examples are given for a risk-based analysis approach to the quality assurance measures that are necessary to consider when establishing a surface brachytherapy program.

“…Some intra-operative applications of ELS have been shown to result in exposure rates to operating room staff of 2 mSv h −1 at approximately 30 cm from a treated area (Mobit et al., 2015). As in all forms of radiation therapy, ELS requires proper initial and ongoing training of the entire treatment team, with detailed attention to personnel, equipment, patient, and personnel safety (Devlin et al., 2017).

In 1928, when 1000 experts in radiology from all corners of the globe gathered in Stockholm for the Second International Congress of Radiology, a key impetus was the protection of x-ray and radium workers in hospitals. This would have included the protection of workers practising brachytherapy with radium sources, which began as early as 1901 (Gupta, 1995). A ground-breaking result was the first international recommendations in this field (ICR, 1929), and the beginning of the long journey for what is now the International Commission on Radiological Protection (ICRP).Today, the work of ICRP is much broader, covering the protection of patients, workers, the public, and the environment from all sources of ionising radiation. However, approximately one-third of ICRP's work still focuses on radiological protection in medicine. This goes beyond the protection of patients to include medical staff, friends and family of patients, and the public who may be impacted. One reason for this is the massive use of radiation in medicine; globally, well over 100 medical examinations and treatments every second use ionising radiation, including approximately one brachytherapy treatment every minute. Another reason is that medical exposures represent approximately 98% of all artificial exposures to ionising radiation (UNSCEAR, 2008).The use of radiation in medicine is continually evolving, and protection must adapt to the new techniques and technologies that continue to improve diagnosis and treatment. Some recent ICRP publications in this area cover radiopharmaceutical therapy, interventional procedures, medical imaging, cone beam computed tomog-

“…Before any irradiation a QA procedure is mandatory and for this purpose the unit uses a diode array (PDA) to verify the dynamic offset of the electron beam and another separate device (PAICH) with a PTW plane parallel 23342 ion chamber to check the output stability. The QA procedure is described in the Zeiss supplied user manual and in the report of AAPM TG-182 [26].…”

Characterization of small active detectors for electronic brachytherapy dosimetry

Three active detectors, Exradin A26 chamber, IBA RAZOR Nano chamber, and PTW 60019 microDiamond, were characterized for their use in electronic BrachyTherapy (eBT) dosimetry. The detectors were calibrated in terms of air kerma using the ISO “N” (narrow) and “TW” (therapy) X-rays series from 7.5 kV to 100 kV. The responses to mono-energetic photons and their uncertainties were determined with Bayesian parameter estimation, assuming a model that incorporated smoothness via a spline function. The response functions obtained this way are consistent with 18 calibration qualities simultaneously. This approach improves on the traditional procedure of associating the response to the mean energy of the corresponding spectra. The energy responses (with uncertainties) were obtained in 0.25 keV energy steps from 6 keV to 70 keV. With differences in magnitude due to their sizes and the nature of their active volumes, the energy responses of the 3 detectors follow a similar relative behaviour. Even when the response is far from flat at low energies, i.e. below about 20 keV, the determination of reliable energy dependence curves enables the use of these detectors for dosimetry in the vicinity of eBT units. The angular dependence of the three detectors with respect to beam incidence was also measured in air in a 180° range in steps of 10° using the Zeiss INTRABEAM system (50 kV). For both energy and angular response characterization, the detectors axis were aligned in parallel with the beam axis (end-on), since this is the expected orientation in further measurements of absorbed dose distribution in water around eBT sources at PTB. This work is an effort to provide traceability for detectors and measurement procedures for the determination of 3D dose distributions as part of the ongoing European EMPIR project “Primary standards and traceable measurement methods for X-ray emitting electronic brachytherapy devices” (PRISM-eBT)”.
