s / Physica Medica 30 (2014) e45ee74 e49 Results: Although all of the 120 sunglasses tested in this study were effective in reducing the intensity of visible light, nearly none of the sunglasses could offer efficient protection against UV radiation. The UVA and UVB transmittance of the sunglasses were in the range of 0.31% (price category of more than 150$) and 72.2% (price category of 30-90$). Conclusion: The majority of sunglasses tested in this study strongly decreased the visible light intensity but couldn’t block all UV radiation. According to the ANSI Z80.3-2001 (U.S. standard) the lens should have a UVB (280 to 315 nm) transmittance of no more than 1%. These findings lead us to this conclusion that these sunglasses can endanger the vision due to dilation of the pupil and overexposure of the lens to UV radiation. MEDICAL PHYSICS TRAINING FOR RADIATION ONCOLOGY RESIDENTS IN GREECE G. Pissakas , S. Nikoletopoulos , P. Georgolopoulou , D. Kardamakis . Hellenic Society of Radiation Oncology, Greece; Hellenic Association of Medical Physicists, Greece; Medical Physics Department, G.Anticancer Athens Hospital “Saint Savvas”, Greece Purpose: Medical physics is an essential part of recommended curricula for residents in radiation oncology (RO). With no official training programs in place, medical physics training is often incidental and incomplete for RO residents in Greece. The aim of this work is to measure the effectiveness of an educational session on medical physics offered to RO trainees of the country. Method: The Hellenic Society of Radiation Oncology (EEAO) hosts quarterly educational meetings for RO residents of all levels. On April 2013 a physics-dedicated meeting was planned for a body of 52 residents. Topics ranged from basic radiation physics, physics of radiotherapy, brachytherapy, 3DCRT, IMRT to physics of specialized treatment modalities. Attendance compared favourably to 30 previous EEAO meetings focusing on clinical issues. Assimilation of material was measured by completion of a test at the end of the meeting focused on main Learning Objectives (LO). Results: Test questions covered all sessions of the meeting with equal weights. Main Bloom’s taxonomy categories were represented. Top 3% of grades achieved corresponded to residents whose home institutes put a substantial effort in training. Students responded better to sessions of an interactive naturewith higher grades on respective LO’s but indicated their enthusiasm over sessions on cutting edge technology. Given the lack of adequately equipped training institutes in the country, this suggests the need for rotation of residents, as recommended by international guidelines on RO training programs (IAEA, ESTRO, ASTRO). Conclusions: Educational meetings for RO residents focused in medical physics are quite effective in bringing together the physics background needed in their clinical practice. The need remains for implementing official training programs throughout the country and for rotation of residents in different institutes during their training.
