| Abstract:: |
| Objective To raise a concept on important standing areas during invasive diagnosis and treatment,measure doses of X-ray radiation,and evaluate distributing characteristics within these areas in order to give suggestions on radiation protection for operators,especially for the principal operator. Methods We measured doses of X-ray radiation from 10 cm to 180 cm above the round within important standing areas during coronary angiography,by choosing a measurement site in every 10 cm away from the radiation field's center.We measured doses of X-ray radiation 3 times at every measurement site under 3 different conditions:no shields were used,using upper and lower radiation protection shields,and using these shields in combination with shielding clothes. Results We successfully measured doses of X-ray radiation in important standing areas during invasive diagnosis and treatment under 3 different conditions,and depicted the distributing sketch maps of doses of X-ray radiatin. Conclusion Radiation protection within important standing areas during invasive diagnosis and treatment plays a vital role in building the invasive radiation system,so we should attach improtance to radiation protection within these areas.Furthermore,we had better use more protection mothods simultaneously,especially the upper and lower protection shields. |
