由于同位素示踪技术具有独特的优点,因此广泛地应用于环境科学技术领域。将放射性同位素合成于被研究的物质分子中作为标记示踪剂。将示踪剂加入所研究的体系中,它将随同类物质一起运动或变化(如污染物在生物链中的迁移)。利用同位素示踪剂的辐射性能,可用放射性探测器定量测定,从而显示出它们的位置及含量而被追踪。放射性示踪技术具有灵敏度(10~(12)—10~(-9)g)高;不破坏样品,甚至使生物体在正常生理条件下,研究物质在生物体内的变化规律;以及测定简便、快速、有的可就地测量等优点。节省人力物力有较好的经济效
Isotopic tracer technology is widely used in environmental science and technology because of its unique advantages. The radioisotopes are synthesized in the molecules of the substance under investigation as label tracer. The tracer is added to the system under study, and it will move or change with the same species (eg, transport of contaminants in the biological chain). Radiation performance using isotope tracers can be quantified using a radioactive detector to track their location and content. Radioactive tracing technique has the advantages of high sensitivity (10 ~ (12) -10 ~ (-9) g); does not destroy the sample, and even makes the organism to study the change rule of the substance in the organism under normal physiological conditions; Fast, some can be measured on the spot and so on. Save manpower and resources have better economic efficiency
