【摘要】：目的探討懸吊防護(hù)屏規(guī)格及擺放位置對(duì)介入手術(shù)中第一及第二術(shù)者輻射防護(hù)效果,為選擇懸吊防護(hù)屏最佳輻射防護(hù)方案提供科學(xué)依據(jù)。方法在第一及第二術(shù)者站位,從地面20 cm至180 cm處,每隔20 cm放置一個(gè)個(gè)人計(jì)量儀。投照體位選擇正位與左側(cè)位。懸吊防護(hù)屏為鉛玻璃(簡稱玻璃式)與鉛玻璃下接鉛橡膠皮(簡稱混搭式)兩種。防護(hù)屏擺位分別為靠近術(shù)者、遠(yuǎn)離術(shù)者、在術(shù)者左側(cè)及貼近球管4種。測(cè)量2種投照體位下,不同防護(hù)屏規(guī)格與擺位在第一及第二術(shù)者位9個(gè)高度的實(shí)時(shí)輻射劑量率,計(jì)算劑量屏蔽率。結(jié)果兩種防護(hù)屏防護(hù)效果接近,以玻璃式略優(yōu)。對(duì)于第一術(shù)者,正位投照時(shí)以近術(shù)者擺位的防護(hù)效果最佳,側(cè)位投照則以術(shù)者左側(cè)擺位的防護(hù)效果最好;對(duì)于第二術(shù)者,正及側(cè)位投照均以近術(shù)者擺位防護(hù)效果最優(yōu)。在最佳擺位情況下:正位投照時(shí)第一術(shù)者在120 cm高度、側(cè)位投照時(shí)第一及第二術(shù)者各高度仍可檢測(cè)到較高的輻射劑量率;第一與第二術(shù)者總體接受的輻射劑量接近;第一術(shù)者的劑量屏蔽率除正位120 cm高度稍低(玻璃式為60.11%,混搭式為39.89%)外,其余各點(diǎn)均高達(dá)93%以上,第二術(shù)者劑量屏蔽率為57%~97%;側(cè)位屏蔽率整體略高于正位屏蔽率。結(jié)論兩種防護(hù)屏防護(hù)效果接近,均能取得較好的防護(hù)效果,但正位投照時(shí)第一術(shù)者的120 cm高度及側(cè)位投照時(shí)2位術(shù)者的各高度輻射劑量率仍相對(duì)較高,需加強(qiáng)對(duì)120 cm高度的輻射防護(hù),并盡量少用側(cè)位投照。
[Abstract]:Objective to investigate the radiation protection effect of the first and second operation persons in the first and second operation of the suspension protection screen and to provide scientific basis for selecting the best radiation protection plan of the suspension protection screen.Methods A personal metering instrument was placed every 20 cm from 20 cm to 180 cm on the ground in the first and second site.The right position and the left position were selected.Suspension protection screen for lead glass (short for short glass) and lead under the rubber leather (referred to as mixed) two types.The position of protective screen was close to the operator, away from the operator, on the left side of the operator and close to the ball tube.The real time radiation dose rates with different protective screen specifications and positions in the first and second operation positions were measured and the dose shielding rates were calculated.Results the protective effect of the two protective screens was similar, and the glass type was slightly superior.For the first operation, the protective effect was best with the proximal position, the best with the left side of the lateral position, and the best with the proximal position for the second operation.Under the optimal setting condition, the first operator was at 120cm height, while the first and second operators could still detect higher radiation dose rate at the first and second height, the total radiation dose of the first and the second operation was close to that of the second operation, and the total radiation dose of the first and the second operation was close to that of the second operation, and that of the first and the second operation was close to that of the second.The dose shielding rate of the first operation was as high as 93% except for the positive 120cm height (60.11 in glass type and 39.89 in the mixing mode), and the shielding rate in the second operation was 57 / 97, and the side shielding rate was slightly higher than that in the positive position.Conclusion the protective effects of the two protective screens are similar and can achieve better protective effects. However, the radiation dose rates of the first operation at the first position and the radiation dose rates of the two at the lateral position are still relatively high.The radiation protection at 120 cm height should be strengthened and the lateral projection should be minimized.
