Fluoroscopy-guided cardiac electrophysiology procedures are among the most critical x-ray exposures. However, occupational doses still little-known. In this study, an alternative methodology was developed to estimate dose and evaluated its optimization in electro-physiology procedures. The were reproduced by simulation rates of staff measured at chest eyes height through electronic dosimeters. ...

background: a new biological dosimeter based on methemoglobin level was developed in this study. materials and methods: methemoglobin level in erythrocytes from mice subjected to γ rays from a 60co source was detected using the methemoglobin kit. the dose range was from 0.5 to 8 gy and the dose rate was 0.5 gy/min. results: the results demonstrate that methemoglobin level increases with increas...
