Rafiology 3

Radiobiology

Study of the effects of ionizing radiation on living tissue

Genetic

Type of cell that includes reproductive cells

Indirect

A theory of radiation injury that suggest x-rays are absorbed and form toxins which damage the cell

Critical organ

If damaged diminishes the quality of a persons life

Latent

A period of time that elapses between exposure to ionizing radiation and appearance of observable clinical signs

Free radical

Unchanged atom or molecule with a single unpaired electron in it’s outermost shell

Radio sensitive

Cell that is sensitive to radiation

Background

A type of ionizing radiation that is ubiquitous in the environment

Risk

the likelihood of adverse effects or death resulting from exposure to a hazard

Direct

A theory of injury thst suggests damage results when ionizing radiation directly hits critical areas within the cell

Somatic

Type of cell that includes all cells in the body except reproductive cells

Short term

Radiation effects that follow the latent period and are seen within minutes, days and weeks.

Radio resistant

Cell that is resistant to radiation

Long term

Radiation effects that follow the latent period and are seen years or generations later.
