Nuclear Energy Flashcards
What is radiation actually caused by?
Decay
What’s the recommended safe amount of Radon you can be around for a year?
500 rems
When 1 large atom splits into two smaller atoms it is called what kind of nuclear reaction?
Fission
Where can I find a real world example of the previous reaction? (Fission)
Nuclear Reactor
When two small atoms combine into 1 large atom it is called?
Fusion
Where can I find a real world example of the previous reaction?
Sun/Stars
What subatomic particle moves around in an atom during a nuclear reaction?
Neutrons
Why is this (neutron) particle able to move in the atom? Because it’s:
Neutral
What scientist discovered an element that can glow and win two noble peace prizes?
Marie Curie
The element the previous scientist discovered is called? (Marie)
Radium
Name the scientific device that shows the path of radioactive particles in a glass globe?
Cloud Chamber
What elements half life is used to measure how old the earth is?
Uranium
How many years old is the Earth?
4.5 billion
What device do we have in our homes that keeps us safe but has radiation in it?
Smoke detector
Rutherford shot radiation through what element to study radiation?
Gold
Most of the radiation went where? (Rutherford)
Straight through
The radiation that didn’t do what the previous answer did, did what? (Rutherford)
Bounced
The result of this experiment led Rutherford to believe that the majority of an atom is?
Empty
Rutherford also learned a second fact, he realized that atoms have?
Nucleus
What source do we receive radiation that comes from above us?
Sun/Stars
When the number of protons and electrons are the same, an atom is called?
Neutron
When the number of protons and electrons are NOT the same, an atom is called?
Ion
When the number of neutrons changes from the original amount, an atom is called?
Isotope
What is the scientific name for the radiation that comes through our ground and into our house?
Radon
We compared the risks of high amounts of radiation exposure in a short time to what?
Alcohol
Scientific name for when a radioactive material is put into the body “see” inside it?
Tracer
If I’m building a NEW house, what material can I use before construction begins?
Plastic/Tarp
What element is the heaviest found in nature?
Uranium
What is the previous answers atomic number? (Uranium)
92
Where do the larger elements on the periodic table come from?
Labs
Name the process when the # of atoms in an atomic reaction keeps x 2? Nuclear:
Chain Reaction
Why don’t nuclear power plants explode? Because the nuclear reaction is-
Slowed
After using material in a nuclear power plant, we unfortunately must deal with what?
Nuclear waste
The two ways in the previous answer must be dealt with are? Away from:
Water/Air and people
There is actually radioactive material in and around us all the time, this is called?
Background Radiation
What can high levels of radiation over long periods of time cause inside our bodies?
Cancer/ Mutations
Lots of radioactive material in a short time can cause death or what?
Radiation Sickness
What device do X-ray technicians wear to monitor how how much radiation they are exposed to?
Docimeter
What is the scientific instrument that measures the amount of radioactive material nearby?
Geiger Counter
Henri Becquerel discovered radiation with what two things?
Film and Uranium
The most dangerous way we can expose ourselves to radiation- and is completely a choice?
Smoking
Write the WORDS for the famous equation for nuclear processes?
Energy=mass x speed of light
What scientist came up with the previous questions formula? (E=mx12)
Einstein
And YOU know the IDEA for this formula is called?
Special Theory of Relativity
Ground radiation is coming in my house- what can I have installed?
Radiation Mitigation System
