|
An unstable nucleus gives off particles and energy.
What is Radioactivity Decay?
|
A Continuous series of nuclear fission reactions.
What is a Nuclear Chain Reaction?
|
10 X 2 = 20 minutes
1/2 of the original Nitrogen-13 of a tooth is unchanged.
How old is the tooth? |
True!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! duh!
True or False
Gamma rays have no mass and charge. |
Steam!!!
Water absorbs energy from the hot coolant and changes into what?
|
|
Can be used to find the age of objects up to 50,000 years old.
What is Carbon-14 used to find?
|
Radioactive elements whose paths can be followed through a process or reaction.
What are Tracers?
|
5,730 X 2 X 2 = 22,920 years old
1/4 of the original carbon-14 of a spear is unchanged.
How old is the spear? |
Healthcare and Industry
What is Radioactivity used in?
|
A Turbine! Attached to a generator.
What does the steam turn?
|
|
Energy is also given off during alpha decay and beta decay. Some of this energy is in the form of light that has very high energy called Gamma Rays.
What are Gamma Rays?
|
State of matter in which electrons have been removed from atoms.
What is Plasma?
|
138 X 2 X 2 X 2 = 1,104 days old
1/8 of the original Polonium-210 of a skull is unchanged.
How old is the skull? |
The release of an alpha particle from a nucleus.
Made up of two protons and two neutrons.
What is Alpha Decay?
What is a Alpha Particle made of? |
Neutrons!!! To keep the chain reaction at a safe level.
What do Control Rods absorb?
|
|
The process by which an unstable nucleus gives off nuclear radiation.
What is Radioactivity?
|
The combination of the nuclei of small atoms to form a larger nucleus; releases energy.
What is Nuclear Fusion?
|
12.3 X 2 X 2 X 2 X 2 X 2 = 393.6 years old
1/32 of the original Hydrogen-3 of a toe bone is unchanged.
How old is the toe bone? |
The release of a beta particle from a nucleus.
Can be a electron or a positron.
What is Beta Decay?
What is a Beta Particle made of? |
water!
What is usually the cooling source?
|
|
An atom that has the same number of protons as other atoms of the same element do but that has a different number of neutrons.
What is a Isotope?
|
The splitting of the nucleus of a large atom into two or more fragments; releases additional neutrons and energy.
What is Nuclear Fission?
|
The time needed for half of a sample of a radioactive substance to undergo radioactive decay.
What is a Half-Life?
|
The release of gamma rays from a nucleus.
The particles in the nucleus shift places.
What is Gamma Decay?
How does Gamma Decay happen? |
Uranium-235 nuclei
What is usually put into the Fuel Rods?
