Structure of Matter
They both weigh about 1.67 x 10-27 kg. Or about one Atomic Mass Unit (AMU)
What is a neutron or a proton?
Henri Becquerel, his graduate student and his student's husband, received a Nobel prize for the discovery of this activity.
What is radioactivity?
This is also known as 'breaking radiation.'
What is Brehmmstrahlung?
In clinical radiation linear accelerator, this is used to power the waveguide with microwave radiation.
What is a magnetron (klystron is acceptable).
The dude who E=mc2 it!
Who is Einstein?
The energy levels of an atom are defined by letters, and the first letter is this, ok?
What is "K" (followed by L, M, N, etc).
This simple mathematical relationship relates the term 'half-life' and the 'decay constant.'
What is the equation
Half Life = 0.693 / Decay Constant
First comes the cathode, then comes the accelerating potential through a vacuum, and finally reaches this 'ode.'
What is the anode?
This is placed in front of an electron beam, before the ion chamber and collimators, to help spread the electron beam.
What is an electron scattering foil.
He developed a model of the atom where electrons surround a nucleus and also hardwired a beer line to his house from a neighboring pub as gift to himself after he won the Nobel Prize.
He wasn't boring at all.
Who is Bohr?
A difference between fermions (quarks and leptons) and bosons (photons and W/Z particles in the weak nuclear force) is in their spins. These particles have an integer spin.
Bosons have spins of (0, 1, 2 ...) and fermions have spins of odd half integers (1/2, 3/2, 5/2, ...)
This would be (calculate!) the final activity of Cobalt-60 (Half life of 5.26 years) of a 5000 Curie source after 4 years.
What is 2952 Curies?
Activity = (Initial Activity) x Exp (-0.693xt/HalfLife))
Activity = 5000 x (Exp(-0.693x4/5.26))
Brehmstrahlung production is proportional to Z and also this factor that changes the energy spectrum.
What is the nominal tube voltage?
Primary and secondary collimators are made mainly of this metal.
What is Tungsten?
Isotopes are atoms with the same number of ... and have a different number of ... ?
What are the same number of protons and have a different number of neutrons?
From shortest to longest wavelength arrange the order of these types of EM radiation:
Radar
Radio
X-rays
X-rays (~10-10m)
Radar (~10 m)
Radio (~10s of meters)
What is alpha decay?
This is a way to make a beam harder without increasing the voltage.
What is filtration?
Of either radiologic or geometric penumbra, this is the one which depends on the size of the source.
What is geometric penumbra?
This kind of boson is hard to find.
Pretty heavy, dude.
What is the Higgs Boson?
Electromagnetic radiation consists of these 2 types of oscillating fields.
Electric and Magnetic Fields
Beta decay results in these (small) particles being emitted from a nucleus.
What is a negatron (like an electron) or a positron?
About 99% of the energy delivered to the anode is converted not into Brehm rays but this.
What is heat?
The energy and half-life of Cobalt-60.
What is 1.25 MeV and 5.26 years.
In the formula E = hf, the constant h is named after him.
He wasn't big on the 'planking' fad.
Who is Max Planck?
