釙210釋放的阿爾法粒子穿透能力很弱,人類的皮膚或一張紙已能隔阻它,粒子經照射影響人體的機會很微,不過由於它的電離能力很強,如果人類吸入或進食含有釙210的物質,其釋放的阿爾法粒子就能直接破壞內臟細胞,即使所吸收的份量不多,也會損害身體健康,急性高劑量阿爾法輻射可以引致輻射中毒。When the inorganic crystal in clay is irradiated by the above radioactive materials, part of the radiation will be released in the form of light and the rest will be trapped in the crystal

當其為成株時已進入夏季,此時自然光照較強, uv - b par的比值較低,在一定程度上削弱了uv - b輻射對玉米的影響,且玉米葉片已發育完全,各種防禦結構和物質也已在發揮作用,因而uv - b輻射對玉米成株無明顯影響。One is about of temperature - dependence of luminescence of eu3 + and tb3 + doped in oxide glass and nanocrystalline y2o3 ; the other is about of light - induced luminescent and structural change in nanocrystalline y2o3 : tb. the creative works are as follows : ( 1 ) euand tb doped nanocrystalline y2o3 with different sizes were prepared by combustion synthesis. dependences of particle size, crystallinity and fluorescence characteristic on ratio of gly / y ( no3 ) 3 and annealing temperature were studied
本文以變溫與光輻照為實驗方法研究了eu與tb摻雜y _ 2o _ 3納米晶及氧化物玻璃中發光性質隨溫度的變化關系和光誘導y _ 2o _ 3 : tb納米晶發光性質及結構的改變過程,得到如下創新性研究成果: ( 1 )用燃燒法制備了稀土摻雜y _ 2o _ 3納米晶,研究了甘氨酸與硝酸釔的反應比例( g n ) 、退火條件對稀土摻雜y _ 2o _ 3納米晶顆粒尺寸、結晶狀況及發光特性的影響。Radioactive matter is incorporated into plants, which are then eaten by animals with the result that most foodstuffs have a measurable amount of radioactivity. additional radioactivity in food comes from the naturally occurring isotope carbon 14. some cosmic radiation also reaches sea level

目前在臨床上治療大面積深度燒傷的方法是移植刃厚或斷層自體皮,但因缺乏足夠的真皮成分,常造成疤痕和攣縮,本實驗用naoh消蝕法研製出一種新的真皮基質( adm ) ,先將其移植于全厚皮膚缺損的大鼠背部創面,外覆蓋輻照豬皮保護3周,使其血管化,再在其上移植斷層自體皮,經動物實驗我們觀察到這種新型復合皮膚,可以減少單純移植刃厚或斷層自體皮造成疤痕和攣縮。In respect of direct radiation in air and from the ground, real - time measurements are undertaken by 10 fixed stations of the radiation monitoring network ( figure 1 ) which send data back to hko every minute. the air is also sampled at these sites to cover the inhalation pathway. to enable early response, an automatic gamma spectrometry system at ping chau, the station closest to daya bay, continuously samples the air, carries out measurements and transmits the results to hko, all automatically
