自从约里奥·居里在1934年发现人工放射现象以后,放射性自显影法在不同的科学领域中得到了广泛的应用。生物学家应用放射性自显影法解决了某些放射性元素在生物体内的分布特点、代谢规律等一系列重要问题。目前在植物学中,放射性自显影应用最广泛的方法是将示踪了的某种放射性同位素的植物样品压平、烘干,并使之与感光胶片接触,在黑暗中进行适当时间的“曝光”。底片“感光”后经过显影与定影处理,即可得到放射性自显影底片。根据自 Since Joel Curie discovered the phenomenon of artificial radiation in 1934, autoradiography has been widely used in different scientific fields. Biologists use autoradiography to solve some of the radioactive elements in the distribution of biological characteristics, metabolic laws and a series of important issues. At present, in botany, the most widely used method of autoradiography is to flatten and dry a labeled plant sample of a certain radioactive isotope and bring it into contact with a photographic film for exposure in the dark for a suitable time “. After the film ”sensitive" after the development and fixing treatment, you can get autoradiography film. According to
