This article throws light upon the various applications of radioisotopes in the biological science. (A) Investigating Aspects of Metabolism: 1. Metabolic Pathways: Radioisotopes are frequently used for tracing metabolic pathways. This usually involves adding a radioactive substrate, taking samples of the experimental material at various times, extracting and chromatographically or otherwise separating the products. Radioactivity detectors can be attached to [...]

Read this article to learn about the basic principles of radioactivity. Radioactivity is a phenomenon that occurs naturally in a number of substances. Atoms of the substance spontaneously emit invisible but energetic radiations, which can penetrate materials that are opaque to visible light. The effects of these radiations can be harmful to living cells but, when used in the right [...]

This article throws light upon the three methods used for detection and measurement of radioactivity. The three methods are: (1) Methods Based Upon Gas Ionization (2) Methods Based Upon Excitation and (3) Methods Based Upon Exposure of Photographic Emulsions. The following figure shows the scheme of basic radiation detector system:   1. Methods Based Upon Gas Ionization: The Effect of [...]
