The harmful effects of radiation. Samples of uranium ores are found to contain as a result of long series of a- and b-decays. The use of energy-rich radiation for the initiation of block- and graft polymerization of macromolecules used in the manufacture of synthetic fibers is discussed. The amount of radioactive material authorized for these licenses ranges from one-millionth of a curie, which is typical for the sources used in gauges, to millions of curries such as those used in large irradiators. Industrial radiography may also be performed in fixed installations, either using the same small portable devices, or using larger machines. These devices contain the sources, detectors and electronic equipment necessary for the measurement. Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. Some important applications are as follows: 1. Radioisotopes find numerous applications in a variety of areas such as medicine, agriculture, biology, chemistry, archeology, engineering and industry. Industrial gauges are used for process control; for measurement of flow, volume, density, or material presence; and may be placed in locations unsuitable for continuous human presence (e.g. The devices generally are not large, but may be located some distance from the radiation detector, which may have electrical or electronic components located within the detector. 1.
