b synthetic elements
B. Synthetic Elements
  • Transuranium Elements
    • elements with atomic #s above 92
    • synthetically produced in nuclear reactors and accelerators
    • most decay very rapidly

C. Johannesson

c radioactive dating
C. Radioactive Dating
  • half-life measurements of radioactive elements are used to determine the age of an object
  • decay rate indicates amount of radioactive material
  • EX: 14C - up to 40,000 years238U and 40K - over 300,000 years

C. Johannesson

d nuclear medicine

Radiation treatment using

-rays from cobalt-60.

D. Nuclear Medicine
  • Radioisotope Tracers
    • absorbed by specific organs and used to diagnose diseases
  • Radiation Treatment
    • larger doses are used to kill cancerous cells in targeted organs
    • internal or external radiation source

C. Johannesson

e nuclear weapons
E. Nuclear Weapons
  • Atomic Bomb
    • chemical explosion is used to form a critical mass of 235U or 239Pu
    • fission develops into an uncontrolled chain reaction
  • Hydrogen Bomb
    • chemical explosion  fission  fusion
    • fusion increases the fission rate
    • more powerful than the atomic bomb

C. Johannesson

f others
F. Others
  • Food Irradiation
    •  radiation is used to kill bacteria
  • Radioactive Tracers
    • explore chemical pathways
    • trace water flow
    • study plant growth, photosynthesis
  • Consumer Products
    • ionizing smoke detectors - 241Am
