Unit 10 Nuclear Fission Flashcards
An unstable isotope
Radioisotope
Continue to decays unless it hits something stable
Radioisotope
Very Large unstable isotope
Fisson
When hit by a neuron, it decays into 2 atoms and 3 neurons
Fission
Creates a chain reaction process
Fission
When 2 small atoms are put under high heat and pressures, the combine
Fusion
Combines into one large atom and neutron
Fusion
Process that fuels the sun
Fusion
Time required for 1/2 of nuclei of radioisotope same to decay products
Half-Life

Shielding Material: 1m of concrete
Gamma
Shielding Material: Goes through everything
Neutron
Travel Distance: Thousands of miles
Neutron
Travel Distance: 6ft

Gamma
Name the 3 types of detectors for radiation
Geiger Counter
Scintillation Detector
Film Badge
How a Geiger Counter works:
-Ionization radiation enters the tube
-electron gets knocked off
-click sounds
-shows amount of radiation showed
How a Scintillation Detector works:
-Ionization radiation enters the tube
-Sodium iodide crystals absorb energy and give off light
-light is multiplied and counted
-tells you how much and what type
How a Film Badge Works:
-Radiation enters the badge
-See how much the filter absorbs
-all nuclear workers were these
What are the 2 purposes of water in the nuclear power plant
Coolant
Absorbs neutrons
What are nuclear power plants similar to
Coal Plants
