Term
Lipids
Definition
Supply for long term storage of energy
Term
Mutation
Definition
The loss of change of a base in the DNA chain
Term
Apoptosis
Definition
When cells die without attempting division during the inter-phase portion of the cell life cycle. programmed cell death.
Term
Point lesion
Definition
.damage to the structure of a biological molecule such as DNA, enzymes, or proteins that results in reduction or absence of normal function
Term
target theory
Definition
radiation damage resulting from discrete and random events
Term
Instant cell death
Definition
when a volume is irradiated with an x-ray or gamma ray dose of approximately 1000 Gyt in a period of seconds or a few minutes.
Term
Reproductive death
Definition
exposure of cells to doses of ionizing radiation in the range of 1 to 10 Gyt.
Term
Mitotic Death
Definition
when a cell dies after one or more divisions.
Term
Metaphase
Definition
the phase of cell division in which chromosome damage caused by radiation exposure can be evaluated.
Term
karyotype
Definition
A cytogenetic analysis of chromosomes may be accomplished through the use of a chromosome map.
Term
radiodermatitis
Definition
a significant reddening of the skin caused by excessive exposure to relatively low-energy ionizing radiation that eventually led to cancerous lesions on the hands and fingers.
Term
cytogenetics
Definition
the study of cell genetics with an emphasis on cell chromosomes.
Term
photomicrograph
Definition
picture that is taken of the human cell nucleus during metaphase.
Term
genetic mutations
Definition
a gonadal dose of 0.1 Gy.
Term
relative biologic effectiveness (RBE)
Definition
relative capabilities of radiation with differing LETs to produce a particular biologic reaction.
Term
target theory
Definition
radiation damage resulting from discrete and random events.
Term
Meiosis
Definition
cell division that leads to the reduction in the number of chromosomes in each daughter cell
Term
target theory

radiation damage resulting from discrete and random events.
Term
Meiosis
Definition
cell division that leads to the reduction in the number of chromosomes in each daughter cell
Term
point mutation
Definition
a transfer of energy, which causes the chemical bond to rupture. If the sugar-phosphate chain side rail is severed.
