Types of Radioactivity
There four major types of radiation...
What are alpha, beta, gamma, and neutron radiation
This type of radioactivity can be generated by medical applications, industrial activities, and nuclear power.
What is artificial radioactivity?
This is the release of energy from the decay of the nuclei of certain kinds of atoms and isotopes
What is radioactivity?
Examples of this kind of radiation are radio waves, visible light and microwaves.
What is non-ionizing radiation?
This type of sickness can be caused by excessive exposure, often causing skin burns, nausea, fatigue, and other side effects.
What is radiation poisoning (or Acute Radiation Syndrome)?
This particle consists of two protons and two neutrons and are the heaviest type of radiation particle.
What is an alpha particle?
The three major naturally occurring sources of radiation are…
What are cosmic radiation, terrestrial radiation (in the earth’s crust), or internal sources found in the human body?
Radiation travels from its source in the form of ____ waves or _____ particles.
What is energy and energized?
Examples of this kind of radiation come from x-ray machines, cosmic particles from outer space and radioactive elements.
What is ionizing radiation?
This use of radiation in archeology measures the age of organic materials.
What is carbon dating?
This is an electron that is not attached to an atom. It has a small mass and a negative charge.
What is a beta particle?
This radioactive isotope is crucial to life and is also an example of an internal radionuclide.
What is Potassium - 40?
This particle can also be represented by the element Helium, since it has two protons and two neutrons.
What is an alpha particle?
Radioactive _____ is the emission of energy in the form of ionizing radiation.
What is decay?
Radiation has benefited humankind since this year of its discovery.
What is 1896?
This is a particle that doesn't have any charge and is present in the nucleus of an atom. They are commonly seen when uranium atoms split, or fission, in a nuclear reactor.
What is a neutron particle?
People are often exposed to artificial radioactivity through medical settings in these types of examinations.
What is an X-ray?
The difference between these two is that one has enough energy to move atoms in a molecule around and the other has so much energy it can knock electrons out of atoms.
What is ionizing and non-ionizing radiation?
The energy of the radiation shown on a spectrum ______ from left to right as the frequency rises.
What is increases?
Radiation plays a large role in the medical world, including these imaging technologies:
What is an x-ray and CT scan?
These particles are widely used in medical treatments and can also be known as electromagnetic radiation. They also have no mass or charge.
What are gamma particles?
This type of natural radiation can be found in the ground, rocks, building materials, and drinking water.
What is terrestrial radiation?
Alpha, beta, neutron, and gamma radiation all come from these types of unstable atoms.
What are radionuclides?
The mission of this organization is to protect human health and the environment from the ionizing radiation that comes from human use of radioactive elements.
Who is the EPA?
Engineers use this process to detect defects in metallic castings and welds.
What is radiography?
