Atomic Building Blocks
The term used to describe something that occupies space and has mass.
What is Matter?
Fill in the blank:
The formula E = mc2 tells us the energy corresponding to a mass (m) that is _ _ _ _ _ _.
What is "at rest"?
The type of DNA break that occurs when ionizing particles deposit energy in a cancer cell.
What is a double stranded break?
This type of radiation is comprised of charged particles and produce an ion by collision with an atom.
What is directly ionizing radiation?
This term describes the linear density of generated charge, and depends on particle charge, velocity and the medium; it generally peaks just before a particle comes to rest.
What is the specific ionization?
The central core or nucleus of an atom is comprised of these two types of particles.
What are protons and neutrons?
It's the energy gained by one electron when it moves through the potential difference of one volt.
What is an electron volt (eV)?
The term used to describe DNA damage to a cancer cell that results in a cancer cell losing its ability to reproduce.
What is cell kill?
This type of radiation involved uncharged particles, and interact with matter to produce directly ionizing particles.
What is Indirectly Ionizing Radiation?
This is the forumula for stopping power.
What is:
SP=(W)(SI)
(where SP is stopping power, W is work, and SI is Specific Ionization.)
The number of protons present in an atom that has a net charge of zero and 50 electrons in its outer cloud.
What is 50?
What is 1.60217653(14) x 10-19 J?
This force involves charged particles, obeys the inverse square law, and is associated with this formula:
F=k((q1q2)/r2))
What is the electromagnetic force?
This collisional interaction involves an incoming high speed electron interacting with an inner orbital electron, promoting the electron to a higher shell.
HINT: The opposite of 'bohring'...lol.
What is excitation?
This is the formula for calculating the range of electrons in water.
What is:
Range=Energy/2
Where Energy is measured in MeV.
Place these particles in order of size from smallest to largest:
Proton, Electron, Neutron, Positron
What is:
Positron, Electron, Neutron, Proton
Note: Protons and Neutrons are roughly the same size, while electrons and positrons are really, really small.
The term that refers to the rest mass or rest velocity.
What is relativistic?
This force involves protons and neutrons, and is charge-independent.
What is the strong nuclear force?
This type of x-ray emission occurs when nuclei deflect incident electrons.
What is Bremsstrahlung?
This term describes the energy transferred per distance travelled.
What is Linear Energy Transfer?
It's rest mass is 1.00727 amu.
What is a proton?
Fill in the missing parts of the formulas below:
Energy = (__)c2
mxc2 = (______) + m0c2
mx = m0 / (_______)
What are:
Energy = (m)c2
mxc2 = (KE) + m0c2
mx = m0 / (√1-(v/c)2)
This force is the weakest and most common; it also depends on mass.
What is the gravitational force?
This particle is more rare than an electron, is sparsely ionizing, creates straight tracks and produces a Bragg peak.
What are Protons?
What are Mass and Charge?
