Study Notes
Radiation Protection
- Dose Limits: Established to prevent acute effects of radiation exposure (e.g., radiation sickness) and to minimize stochastic effects (e.g., cancer)
- As Low As Reasonably Achievable (ALARA): Principle of minimizing radiation exposure to individuals and the environment
- Shielding: Use of barriers to reduce radiation exposure (e.g., lead, concrete, water)
Waste Disposal Methods
- Deep Geological Repository: Long-term storage of high-level waste in stable, geological formations (e.g., Yucca Mountain, USA)
- Vitrification: Conversion of liquid waste into a solid, glass-like material for safer storage
- Near-Surface Disposal: Shallow land burial of low-level waste in engineered facilities
- Sea Disposal: Dumping of low-level waste into the ocean (no longer practiced)
Radioactive Decay
- Half-Life: Time required for half of the radioactive atoms in a sample to decay
- Radioactive Decay Modes: Alpha, Beta, and Gamma radiation emissions
- Decay Chain: Series of radioactive decays leading to a stable isotope
- Radioactive Equilibrium: Balance between radioactive decay and ingrowth of radioactive isotopes
Environmental Impact
- Environmental Monitoring: Continuous surveillance of radiation levels in air, water, and soil
- Dose Assessment: Calculation of radiation exposure to humans and biota
- Radioecology: Study of radioactive materials in the environment and their impact on ecosystems
- Waste Transportation: Safe transport of radioactive materials to minimize environmental impact
Radiation Protection
