Materials and Methods A special episode of Rad Chat was recorded: “Outcomes from the Radiation Reveal Project” (https://bit.ly/3eKlz8p). Discussions with Dr. Lisa Whittaker, Mia, Kate and Holly focused on the CRUK RadNet City of London public engagement project 'Radiation Reveal', its outcomes, top tips and aspects of care that could be improved. Using this podcast episode, listeners were asked to complete a 12-question survey. Results 14 podcast listeners completed the online pilot survey; 50% of them classified themselves as therapeutic radiographers, with other listeners identifying as pharmacists, researchers, and PhD students. Most listeners use podcasts to be informed, with 36% of them listening to podcasts daily and 29% of them weekly. Most therapeutic radiographers find podcasts accessible (85%), effective for sharing research (93% rated it 7 or higher in a scale of 0 to 10, with 0 being not effective and 10 being highly effective) and 100% use them as part of their CPD and learning. This highlights that, at least for the radiographers' outcomes, it was likely that results are skewed by a population that already listen to Rad Chat. 72% of the survey participants would like to listen to more CPD-themed podcasts based on this episode. They described it as “a very accessible and engaging way to learn”, and “very helpful.” Lasting impressions included the importance of consulting with young adults living with and beyond cancer to adapt their treatment and care, taking into account their priorities and the fact that effective communication and listening to the patient can greatly impact and improve their treatment experience. Importantly, all therapeutic radiographers that completed the survey stated that listening to this podcast inspired them to change some aspects of their practice. The value of public engagement was also highlighted, with listeners thinking to participate in more public engagement projects. Radiation Reveal Poster discussed in the episode. Conclusion This podcast promotes listeners to reflect on their own practice, inspired them to further personalise the way they approach their patients and prioritise patients’ needs and questions. However, there is a need to ensure a broader reach of listeners, including scientific researchers, and continue acquiring feedback. Purpose or Objective Compliance with radiation protection rules is fundamental in radiotherapy given the radiation risk incurred by workers exposed in their work establishment. Wearing a personal dosimeter during professional activity provides individual protection for these workers. The purpose of this study is to evaluate the interest and the respect of the dosimeter wearing by the workers exposed to ionizing radiations in our department of radiotherapy. Materials and Methods This is a descriptive prospective study carried out among 30 workers (11 physicians, 5 physicists, 14 radiotherapists) and based on a questionnaire composed of 6 parts: 1st part: 5 general questions, 2nd part: two questions about the knowledge evaluation concerning the ionizing radiations types, 3rd part consisting of four questions about the knowledge evaluation concerning the radiations effects, 4th part consisting of 5 questions about the knowledge evaluation concerning dosimetric quantities and radiation protection standards, 5th part composed of 10 questions about the knowledge evaluation concerning dosimetry and dosimetric monitoring and 6th part composed of an only question about the level of workers satisfaction with the dosimeter used results in their departement. Results The knowledge evaluation concerning the ionizing radiation types showed that a large part of the participants defined (40%) and differentiated them (60%). For the ionizing radiation biological effects, the majority of participants (95%) declared knowing them, however, only 16% were able to differentiate the types of these effects. On the other hand, the knowledge level concerning the clinical effects was satisfactory. In terms of dosimetry, the majority of participants (75%) found it difficult to define dosimetric quantities and radiation protection standards. By analyzing the answers to the questions about the knowledge evaluation concerning dosimeters, their use and dosimetric monitoring, we noted that there was a satisfactory knowledge level concerning these areas, apart from the question about the dosimeters types where only 30% of the participants were able to answer this question correctly. For the satisfaction level concerning the dosimeter used results, more than half of the participants (60%) were not satisfied. Conclusion The results of this study show some insufficiencies concerning the knowledge level of some physical bases and radiation protection as well as the dissatisfaction of the participants concerning the dosimeter used results. New reforms should therefore be envisaged by developing the culture of continuous training and awareness of radiation protection and by ensuring a well clinical follow-up.
