CHROMOSOMES BREAK
Term
DIRECT ACTION
Definition
biologic damage occurs as a result of ionization of atoms on essential molecules produced by straight interaction with the incident radiation

INDIRECT ACTION
Definition
multistage process that first involves the production of free radicals that are created by the interaction of the radiation with water
Term
FREE RADICALS

linear energy transfer (LET)
Definition
The average energy deposited per unit length of track
Term
MUTATION
Definition
loss or change of a base in the DNA chain
Term
POINT LESION
Definition
energy transferred could rupture one of its chemical bonds
Term
DNA
Definition

three-dimensional structure of double-stranded DNA, in which polymeric nucleotide strands whose complementary nitrogen bases are linked by hydrogen bonds form a helical configuration
Term
ABBERATION
Definition
a characteristic that deviates from the normal type
