ANTITOXIN – An antibody that neutralizes a biological poison.
BARRIER NURSING METHODS – Nursing techniques designed to prevent contact with a patient’s blood or secretions. These include the wearing of protective clothing such as masks, gloves, gowns and goggles, the use of infection-control measures, including equipment sterilization and complete isolation of the patient. (Also: Standard Precautions.)
CARRIER – A person or animal that harbors a specific infectious agent without visible symptoms of the disease. Can be a potential source of infection.
CHLORINE – An irritating, potentially lethal, greenish gas commonly used in disinfectants and bleach.
CHRONIC – Lasting for a long period of time or marked by frequent recurrence.
CONTAINMENT (Building/structure) – A structure found at nuclear power plants designed to contain any radioactive materials that may be released from the nuclear reactor fuel and cooling systems.

EPIDEMIC – The occurrence of cases of an illness in a region in excess of what is normally expected.
EPIDEMIOLOGY – The study of the spread of diseases.
EXCRETION – Elimination of wastes.
FALLOUT – The descent to the earth’s surface of particles contaminated with radioactive material from a radioactive cloud. The term can also be applied to the contaminated particulate matter itself.

FISSION PRODUCTS – A complex mixture of substances produced as a result of nuclear atoms splitting (fission).
HEMORRHAGIC – Bleeding.
HEPATITIS – Inflammation of the liver, caused by infectious or toxic agents and characterized by jaundice, fever, liver enlargement and abdominal pain.

IMMUNITY – Inherited, acquired or induced resistance to infection by specific pathogens.
INCUBATION – The development of an infection from the time the pathogen enters the body until signs or symptoms first appear.
INDIGENOUS – Native.
INFECTION – The entry and development of an infectious agent in the body of a person or animal.
INFECTIOUS – Invaded by toxic microorganisms, causing injury.
INGESTION – Swallowing.
INHALATION – Breathing.
ISOLATION – Setting apart or cutting off from others. Quarantine.
JAUNDICE – Yellowish discoloration of the whites of the eyes, skin and mucous membranes caused by deposition of bile salts in these tissues.
LESION – A wound or injury.
LYMPHATIC – Related to the clear, watery fluid containing white blood cells that circulates in the body and acts to remove bacteria and certain proteins from the tissues, transports fat from the small intestine, and supplies mature lymphocytes (cells related to immunity) to the blood.
MACE – An irritating chemical spray used in crowd control.
MALAISE – A feeling of illness or depression.
MENINGITIS – Inflammation of the membranes which enclose the brain and the spinal cord, most often caused by a bacterial or viral infection. It is characterized by fever, vomiting, intense headache and stiff neck.
MIOSIS – Excessive contraction of the pupil of the eye.
MORBIDITY – The rate of incidence of a disease.
MORTALITY – Frequency of death in a population.
MUCOSA – Membranes lining all body passages that communicate with the air, and have cells and associated glands that secrete mucus. Also called mucous membrane. Mucosal adj.
PARALYSIS – Loss or impairment of the ability to move a body part, usually as a result of damage to its nerve supply. Loss of sensation over a region of the body.
PHOSGENE – A colorless, potentially lethal, liquid or gas.
