1. Nuclear Technology Overview:
– Nuclear technology’s history involves the discovery of radioactivity by Henri Becquerel in 1896.
– The understanding of radiation types led to safer applications in modern technology.
– Nuclear fission involves splitting a nucleus, leading to the development of atomic bombs during World War II.
– Fusion in stars creates light and heavy elements through nucleosynthesis processes.
– Controlled fusion for energy production remains a challenge, with ongoing research efforts.
2. Applications of Nuclear Technology:
– Nuclear technology is used in reactors, medicine, and weapons.
– Radium salts were historically used in glowing dials on meters.
– Radioactive materials are still applied in various industries, including energy production.
– Nuclear power provides about 15.7% of the world’s electricity.
– Medical applications include radiography, radiopharmaceuticals, and radiation therapy.
3. Nuclear Power and Energy Production:
– Nuclear power plants use fission for electricity generation.
– Nuclear power provides approximately 15.7% of global electricity.
– Nuclear power is used in propulsion of aircraft carriers and submarines.
– Controlled fusion has not yet produced a viable electricity source.
– Man-made fusion reactions have not resulted in a practical energy solution.
4. Industrial and Commercial Applications:
– X-rays and gamma rays are used in industrial radiography for testing.
– Radioactive tracers are used in industrial processes for monitoring and control.
– Commercial applications include radioluminescence, tritium illumination, and betavoltaics.
– Food irradiation is used for sterilization and preservation.
– Radiation-induced mutations benefit biology and agriculture.
5. Environmental Impact and Safety Concerns:
– Nuclear energy reduces 470 million metric tons of CO2 emissions annually.
– Safe disposal and recycling of low nuclear waste are practiced.
– Health hazards and concerns related to induced radioactivity are unresolved.
– Industry advocacy groups address misconceptions about food irradiation.
– Differentiation between food irradiation and pasteurization remains a topic of debate.
