Detailed data collection of radioactive tracer method

Radiotracer method is a scientific means to add detectable radionuclides to chemical, biological or physical systems and mark the research materials to track the process, running state or study the material structure. This radioactive tracer is called tracer atom or labeled atom. This item introduces the principle and characteristics of this method, the characteristics of tracer and the application of radioactive tracer in chemistry, biology and biochemistry.

Basic introduction Chinese name: radioactive tracer mbth: application fields of radioactive tracer: chemistry, biology, biochemistry, etc. Related disciplines: nuclear chemistry, biology, biochemical process: labeling and tracing key points: introduction of tracer atom or labeled atom, definition, principle, characteristics, application scope, development prospect and definition. Radiotracer method Because radionuclides emit radiation continuously, it is easy to detect its whereabouts with detectors wherever it moves, so it can be used as a tracer to distinguish the movement and change laws of other substances. This radioactive tracer is called tracer atom or labeled atom. Radioactivity is a substance with special marks. When it is added to the research object, people can understand the movement and change law of the research object according to its movement and change. The application of tracer implies two assumptions: first, the chemical properties of radionuclides and their stable isotopes are the same; Second, the chemical characteristics of the research object are not affected by radioactive decay. The first assumption is incorrect only when the mass effect of isotopes is important. As long as the tracer concentration is small, the second assumption is correct. Characteristics 1, high sensitivity and detectability
