| Abstract:: |
| Objective To investigate the radiation dose levels to the adults examined from diagnostic exposure in Beijing.Methods The radiation doses to the examined individuals were measured by using individual diagnostic radiology equipments in 30 random hospitals from a total of 10 districts and suburban areas, including 1 182 samples of X-ray photography,542 samples of mammography and 410 samples of CT examination.Results 2 134 samples were measured in this study. The dose ranges of X-ray photography, CR, and DR were 0.4-24.1, 0.3-13.9 and 0.1-15.9 mGy, respectively. The average dose range of glandular breast was 0.3-5.4 mGy. In 410 CT samples the value of CTDIw, CTDIvol and DLP were 28.1-96.3 mGy, 7.0-23.4 mGy, and 162.2-898.1 mGy ·cm, respectively. Conclusions Several dose levels from diagnostic examination were higher than guidance level for medical exposure in GB 18871-2002,which should be noted. |
