描述In biological literature, several definitions of quantitative autoradio- graphy are given. The term is defined as either the determination and com- parison of the density of silver grains above various structures or under varying conditions, or the determination of absolute quantities of radio- activity. In both these cases, photometric measurement serves for more rapid and more exact evaluation of grain densities than would be possible by visual counting of the grains. The equipment generally used for the photometric measurement of silver grains consists of a microscope, a photocell, an electronic amplifier system and a display unit. Grains can be made accessible to photometric evaluation by various kinds of microscopic illumination: 1. Substage bright-field illumination. 2. Substage dark-field illumination. 3. Incident dark-field illumination. 4. Vertical bright-field illumination. With all these types of illumination, the relationship between the luminous flux I absorbed by the film, scattered into the objective and reflected or diffracted, and the flux 10 which is not affected by the film is used as a measure of grain density. Since these are differential measurements, the ligh

Microautoradiography of Water-Soluble Organic Compounds,half-life are available for use as tracers. .PO. = and .SO.=, when occurring as monoesters, can be precipitated as lead and barium salts respectively, as described in Chapters 3 and 7. Procedures treated in this chapter deal mainly with .H- and .C-labeled compounds.

Botanical Applications of Microautoradiography, the classical monograph of microautoradiographic techniques published in 1955 by ., botanical applications are extremely few. And even in more recent publications (., 1967; . and ., 1971) there is very little reference to microautoradiographic work with plant material (in addition, see chapter 16 in ., 1962).

Autoradiography with the Electron Microscope: Experimental Techniques and Considerations Using Planny other scientific method it can only yield valuable results when its limitations are clearly recognized, stated and evaluated where possible. More recently, several elegant and important autoradiographic experiments have been published illustrating these limitations and methods of evaluating them (see Section 6.15).
