1 of 3
- emit radiation used to diagnose and treat various medical conditions
- utilizes radioactive materials to produce detailed images of organs and tissues
- (PET) scans detect metabolic activity in cells aids in cancer diagnosis
- (SPECT) creates 3D images of organs helps assess blood flow and function
- targets cancer cells with high-energy radiation destroys or shrinks tumors
- directs radiation from outside the body to specific tumor locations
- involves placing radioactive sources directly into or near tumors for localized treatment
Radiation Measurement and Safety
- measures and calculates radiation doses received by patients and medical staff
- (TLDs) measure cumulative radiation exposure over time
- detect and measure radiation exposure for personnel working with radioactive materials
- ensure safe handling of radioactive materials in medical settings
- and protect patients and staff from scattered radiation during procedures
- Time, distance, and shielding principles minimize radiation exposure in medical environments
Industrial and Research Applications
Age Determination and Archaeological Studies
- determines the age of organic materials up to approximately 50,000 years old
- (C-14) decays at a known rate allows scientists to calculate the age of archaeological artifacts
- combines carbon dating with tree ring analysis for more precise dating
- measures the decay of potassium-40 to argon-40 dates rocks and minerals millions of years old
- utilizes the decay of uranium isotopes to lead determines age of ancient rocks and minerals
Energy Production and Industrial Processes
- Nuclear power generates electricity through controlled fission reactions in nuclear reactors
- (PWRs) use water as both coolant and moderator most common reactor type
- (BWRs) allow water to boil directly in the reactor core simpler design than PWRs
- Nuclear-powered ships and submarines use small reactors for long-range, extended missions
- Radiation used in industrial processes sterilizes medical equipment and food products
- employs gamma rays or X-rays to inspect materials for defects in manufacturing
Radiation Safety and Environmental Monitoring
- establish safe exposure limits for workers and the public
- monitor individual radiation exposure in various industries
- detects and measures radioactivity in air, water, and soil
- in buildings identifies potential health hazards from naturally occurring radioactive gas
- (lead, concrete, water) reduce exposure in industrial and research settings
- remove radioactive materials from surfaces and equipment
Military Applications
Nuclear Weapons Development and Testing
- Nuclear weapons harness the energy released from nuclear fission or fusion reactions
- (atomic bombs) split heavy atomic nuclei releases enormous energy (uranium-235, plutonium-239)
- (hydrogen bombs) combine light atomic nuclei produces even greater explosive yield
- conducted by various nations to develop and refine weapon designs
- Atmospheric nuclear tests banned by the of 1963 reduced radioactive fallout
- Underground nuclear testing continued until the of 1996
Nuclear Deterrence and Arms Control
- strategy aims to prevent war by threatening overwhelming retaliation
- (MAD) doctrine maintained balance between superpowers during Cold War
- consists of land-based missiles, submarine-launched missiles, and strategic bombers
- (NPT) limits the spread of nuclear weapons technology
- (IAEA) monitors compliance with nuclear safeguards agreements
- Nuclear disarmament efforts reduce stockpiles and limit development of new nuclear weapons
