What are some environmental or health concerns associated with mining uranium ore? The uranium mining process requires large amounts of corrosive materials that pose occupational health risks. The percentage of Uranium-235 (U-235) is enriched from 0.7% to a dangerous 90% in pellets used in fuel rods. Uranium miners get higher than normal cancer rates from their high exposure to radioactive elements. Mining and enrichment of uranium, as well as the production of fuel pellets, creates hazardous waste. The high concentration of radioactive materials in uranium mines increases the risks of a nuclear explosion. incorrect

In what ways are boiling water nuclear reactors (BWR) different from pressurized water nuclear reactors (PWR)? A BWR is safer than a PWR because it requires less built-up pressure to generate steam. A BWR uses the same water source to create heat and steam, whereas a PWR uses separate water sources for heating and steam. A BWR makes all components of its system radioactive, whereas a PWR contains radiation only in its core. A BWR uses the external environment as a cooling source, whereas a PWR uses water as a cooling source.

The highly radioactive isotopes that produce power through nuclear fission spontaneously release large amounts of radiation in a process known as radioactive decay. Radioactive decay is measured in half-lives. An isotope's radioactive half-life is the amount of time it takes for half of the radioactive material to decay to a new form. After one half-life. 50% of the material will decay. In the next half-life, 50% of what is left, or 25% of the original amount, will then decay, and so on. If a radioactive isotope has a half-life of 50 days, how many days will it take for a 100 g sample of the isotope to decay and have only 6.25 g remaining? amount of time: 400 Incorrect days
