Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus
Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
متن کاملConsider potential of gold nanoparticles with proton therapy compared with KV and MEV X-ray therapy.
Introduction: Many study shown the effectiveness dose enhancement with gold nanoparticles (GNPs), especially with low-energy x-rays. Recently, proton beam radiation therapy (PBRT) has attention as a treatment for tumors. The advantage in PBRT, which releases high dose at the controllable Bragg peak position that localized for Au target and the released dose increased in depth....
متن کاملradioprotective effects of lentil sprouts against x-ray radiation
the present study investigated the radioprotective efficacy of lentil ( lens culinaris ) sprouts against x-ray radiation-induced cellular damage. lentil seeds were dark germinated at low temperature and the sprout extract was prepared in pbs. free radical scavenging of extract was evaluated using 2,2-diphenyl-1-picrylhydrazyl (dpph) assay and then the radioprotective potency of extract (0 to 10...

متن کاملRadiation exposure of the Yazd population from medical conventional X-ray examinations
Background: Radiation dose knowledge through Xray examinations and their distribution in Iran provides useful guidance on patient dose reduction. The results of the entrance skin dose (ESDs) of five common radiographies in all radiology centers in Yazd province were reported in our previous study (2003). In the present study we have evaluated the collective effective dose of convention...
