Term
apoptosis
Definition
programmed cell death
Term
point lesion
Definition
damage to biological molecule structure
Term
mutation
Definition
loss or change in DNA base
Term
free radicals
Definition
behave as single entities and are very chemically reactive as a result of the presence of unpaired valence (outermost) electrons
Term
DNA
Definition
The molecule inside cells that contains the genetic information responsible for the development and function of an organism

Definition
ribonucleic acid
Term
LET
Definition
linear energy transfer, average energy deposited per unit length of track
Term
Target theory
Definition
random and discrete events causing radiation damage
Term
RBE
Definition
relative biologic effectiveness, relative capabilities of radiation with differing LETs to produce a particular biologic reaction
Term
OER
Definition
oxygen enhancement ratio oxygen effect represented numerically
Term
Nucleic acid

calculates equivielent dose to determine dose of biologic damage
Term
chromosomes
Definition
structure of nucleic acid and protein in the nucleus of living cells
Term
nucleus
Definition
controls multiplication and division of cells
Term
Telophase
Definition
internal structures begin to re establish, cell is finishing division
Term
direct action
Definition
straight interaction with the incident radiation
Term
indirect action
Definition
multistage process that first involves the production of free radicals that are created by the interaction of the radiation with water molecules
