Dose evaluation in medical staff during interventional radiology procedures
(2015-01-01)
Interventional Radiology is the radiology modality that provides the highest dose values to medical staff. Recent researches show that personal dosimeters may underestimate dose values in interventional physicians, especially ...
Study of the effects of exposure to ionizing irradiation on the materials used for dental restoration
(Medimond S R L, 2002-01-01)
A quantitative study was made about the effects caused by ionizing irradiation on materials used for dental restoration (amalgams, compound resins and compomere), aiming to alleviate in bearers of head and neck cancer, the ...
Mechanical properties of HIPS/sugarcane bagasse fiber composites after accelerated weathering
(Elsevier B.V., 2011-01-01)
The effect of accelerated weathering on the visual appearance and on mechanical properties of high impact polystyrene (HIPS) as well as HIPS reinforced with mercerized and bleached sugarcane bagasse fibers composites are ...
Evaluation of geomembrane UV degradation using melt flow index and oxidative induction time tests
(Zhejiang Univ Press, 2008-01-01)
Many factors such as the sunlight, intensity of radiation, temperature, and moisture may influence the degradation process of geosynthetics. UV stabilizers are used especially in polyolefin geomembrane to prevent the ...
