shield

Etymology: AS, scild
a toxic neurological condition that results from eating clams, oysters, or mussels that have ingested the toxin-producing protozoa commonly called the red tide. The characteristic symptoms appear within a few minutes and include nausea, light-headedness, vomiting, and tingling or numbness around the mouth, followed by paralysis of the extremities and, possibly, respiratory paralysis. Saxitoxin, the causative agent, is not destroyed by cooking. However, the severity of the illness is diminished if the water used in cooking is not consumed. See also Gonyaulax catenella, venerupin poisoning.

shield

Etymology: AS, scild
a material for preventing or reducing the passage of charged particles or radiation. A shield may be designated by the radiation it is intended to absorb, such as a gamma ray shield, or by to the kind of protection it is intended to give, such as a background, biologic, or thermal shield. Lucite and aluminum can be used for beta-radiation shields, but lead is required for gamma ray shields.
