Nuclear Physicists
Deployed the first mobile x-ray machine to war sites during WWI
Who was Marie Curie?
What is an alpha particle?
1.67262 × 10−27 kg
What is the mass of a proton?
Form of radiation capable of removing electrons from atoms
What is ionizing radiation?
The loss of an alpha particle
What is alpha decay?
Refused to believe in the existence of radiation, but known to have developed the first periodic table
Who was Dmitri Mendeleev?
When a neutron loses this particle it becomes a proton.
What is an electron (aka a beta particle)?
"k" in A = Ao + e^kt
What is the decay constant?
A facility where the rate of nuclear decay is controlled
What is a nuclear reactor?
When neutrons strike larger nuclei causing them to break into pieces
What is fission?
Discovered atoms have a positively charged particle in the nucleus using alpha-particles and gold foil
Who was Ernest Rutherford?
A unit of energy, or photon, capable of destroying DNA bonds
What is gamma?
1.674 927 498 04 x 10-27 kg
Atoms of the same element containing varying amount of neutrons
What are isotopes?
Radioactive substances enter the body to illuminate structures for diagnostics
What is nuclear medicine?
Realized that mass and energy are equivalent and published information useful for building an atomic bomb
Who was Albert Einstein?
When a proton becomes a neutron by losing this particle. Be specific.
What is a positron (aka a Beta + particle)?
Detection of particles decreases proportionally as distance from the source increases
What is the inverse square law?
Energy needed to remove a particle from a given nucleus
What is binding energy?
The use of high speed electrons to trigger the release of high energy photons, which produce images on film
What are X-Rays?
Married couple who won the Nobel Prize in 1935 for successfully inducing radioactivity on smaller elements, such as Aluminium
Who were Irene and Frederic Joliot-Curie?
This subatomic particle is not part of the binding energy equation due to its location in the atom.
What is an electron?
"c" in E = mc^2
What is the speed of light?
Raw material from the earth within which Marie Curie discovered Radium
The loss of a beta particle by an unstable nucleus
What is beta decay?
