Any Material that contains unstable (radioactive atoms). The unstable atoms emit radiation.
What is Radioactive material.
Name the 3 main types of radioactive contamination.
What are fixed, airborne, and removable.
This particle has a large mass and a +2 charge (2 protons, 2 neutrons).
What is an Alpha Particle.
Mass of a Proton aka (Mp)
What is 1.00727 amu
Pu-239 has a half-life of _______
decays by a ______
with a primary energy level of ______
2.410E04 a
alpha
5.156 MeV
Radiation that has enough energy to excite electrons to move up another shell and , as they return to their original shell, they release photons in the form of visible light, uv light, radar waves, and microwaves, but the energy level is too low to ionize atoms.
What is Non-ionizing Radiation
The process of unstable (radioactive) atoms releasing radiation to become stable.
What is radioactivity.
No charge but has mass.
What is a Neutron Particle.
Mass of an electron aka (Me)
What is 0.000548 amu
Rad
What is Radiation absorbed Dose
Energy emitted from radioactive atoms and some devices that can cause ionization.
What is radiation.
The time it takes for one half of the radioactive atoms present to become stable.

Rem
Radioactive material in an unwanted place.
What is radioactive contamination.
The process of unstable (radioactive) atoms releasing radiation over a period of time to reach stability. AKA known as disintegration.
What is Radioactive decay.
The process of changing non-radioactive material into radioactive material.
What is Activation.
Atomic mass from the "Chart of the Nuclide"
AKA (Ma)
