Would you say there's a Transfer of Energy?
The number of ion pairs formed by the particle per unit path length
Specific Ionization
Types of radiation that have no charge or coulomb force field extending beyond their physical dimensions and must come close to particles in order to interact are referred to as this
Indirectly ionizing radiation
Name one of the Neutron Energy Categories
Thermal, Intermediate, Fast, Relativistic
What are the building blocks of which man and his living environment are composed?
Cells
These organelles of a cell are ruptured at dose levels between 500 and 100 rads
Lysosomes
The average energy locally deposited in an absorber resulting from a charged particle per unit distance of travel
Linear Energy Transfer
What's the difference between an X-ray and a Gamma ray?
Their origin
(Gammas are from the nucleus, X-rays are from the electron cloud)
Thin amounts of almost any material can shield this radiation type
alpha
Which part of a cell helps to regulate the concentration of water, salts, and organic matter that form the interior environment of the cell?
Cell membrane
How much absorbed dose will it take to rupture the cell membrane?
3,000-5,000 rads
The average energy lost by a charged particle per unit distance traveled
Stopping Power
A gamma interacts with an orbital electron, transferring part of its energy to said electron and continuing with less energy, removing the electron and resulting in an ion pair
Compton Scattering
Rubber, aluminum, and plastic can shield this radiation type
Beta
What within a cell contains digestive enzymes that break down large molecules into smaller constituents that can be oxidized by the mitochondria?
Lysosomes
Radiation passing through living cells which will directly ionize or excite atoms and molecules in the cell structure is considered which type of effect/reaction?
Primary
Beta particles transfer energy through which three interactions?
Excitation, Ionization, Bremsstrahlung
A gamma or photon transfers all of its energy to an orbital electron and vanishes, removing said orbital electron and resulting in an ion pair.
The Photoelectric Effect
Which radiation particles, if allowed to be deposited internally, become a very serious health hazard?
alpha
Something within you comes alive like a sleeper cell when I say "The Powerhouse of the Cell"...
Mitochondria
According to the Law of Bergonie and Tribondeau, cells that have a high division rate, a high metabolic rate, and are well nourished are what?
Radiosensitive
Excitation and Ionization
A gamma of at least 1.022 MeV disappears in the vicinity of a nucleus and in its place are two anti-particles--an electron and a positron. The positron seeks out a free electron and annihilates, converting back from mass into two gammas of 0.511 MeV each.
Pair Production and Annihilation
This interaction occurs when a neutron strikes a nucleus, typically of approximately the same mass as the neutron, recoils off and loses energy
Elastic Scattering
The center of control of a cell, directing cellular activity and containing hereditary information
Nucleus
Any dose, however low, has a certain probability of causing effects. This increases with dose, without threshold. What are these effects called?
Stochastic Effects
