- Nuclear Science and Technology
Nuclear Power Plant Applications: Radiotherapy, smoke detectors, sanitation of disposable products, and Radioisotope Thermal Generators used in space missions are all examples of industries that use radioisotope thermal generators.
Massive amounts of energy are released as atoms’ nuclei undergo modifications. All approaches that manipulate/control such changes in the nucleus of particular specific elements and convert them into useful energy are referred to as nuclear technology.
It is widely utilized to generate electricity in nuclear power plants. Nuclear power is a cost-effective and environmentally friendly method of boiling water to generate steam, which is then used to turn turbines to generate electricity.
In deep space missions, nuclear elements can provide a reliable, long-term supply of electricity. Nuclear batteries allow spacecraft to run unsupervised for years. For example, the Voyager 1 and 2 spacecraft, which were launched in 1977 to probe the solar system’s furthest reaches, is still transmitting data today.
Nuclear technology is also employed in gun sights, medical radiography, and the sterilizing of tools and equipment, in addition to generating power.
Applications include the use of microbes in the production of organic products such as milk and bread, the extraction of metals from their ores using live organisms (bioleaching), and the development of biological weapons.
