放射自显影术(Autoradiography)是利用放射性同位素产生的核射线,使照相乳胶中的溴化银粒感光,产生潜影,通过显影溴化银还原为金属银而现出影像,根据影像中的银粒所在部位与数量判断标本或样品中放射性物质的分布、定位和定量的方法。放射自显影术不同于其它测量放射性的方法,它可永久记录核粒子的径迹,能获得核粒子在空间的分布;
Autoradiography is the use of radioactive isotope nuclear radiation, the photographic emulsion of silver bromide particles sensitized to produce latent images, through the development of silver silver reduced to silver and the emergence of images, according to the image of silver Method of determining the distribution, location and quantification of radioactive material in a specimen or sample by the location and quantity of the particle. Autoradiography is different from other methods of measuring radioactivity, which can permanently record the trajectory of nuclear particles and obtain the distribution of nuclear particles in space.
