摘要
研究了气载14C进入鹌鹑体内并在其各部位的累积、分布动态。结果表明:少量气载14C通过呼吸、沉降及摄食等途径进入生物体并向各部位转移;14C比活度随气载14C等量等时间间隔的多次引入呈线性增长趋势,胃内皮与肝脏两个部位对14C累积效应明显,分别符合线性方程y=4.6321x+3.7747(R2=0.9838)、y=3.6703x+6.3317(R2=0.9957);肉、骨两个部位14C放射性的分布百分比较高,分别达30%～45%和20%～30%。
The accumulation and distribution dynamic of airborne ^14C in different parts of quail was studied by using isotope-tracer technology. The results showed that： a little airborne ^14C into quail via breathing, sedimentation and ingestion transferred to all pats of organism. The accumulation effect of ^14C in endothelium of stomach and liver was evidence. Their specific activity of ^14C increased linearly along with immitting of airborne ^14C by equally dose and time distance, which accorded with linear equations y = 4.6321x ＋ 3.7747 （R^2 = 0.9838） and y = 3.6703x ＋ 6.3317 （R^2= 0.9957） respectively. Radioactivity percent of 14C in meat and born are higher than other parts of quail and goes to 30%-45% and 20%-30% respectively.
