Reduction of transmitted sound energy or its electrical equivalent.
Premature termination of an elongating RNA chain.
A reduction in the effect or strength of something such as a virus, either because of environmental conditions or as a result of a laboratory procedure.
Process of weakening, especially of the potency of a drug or other agent or of the virulence of a disease-causing germ.
Reduction of the intensity of a beam of radiation by interaction with some medium. Attenuation is a complex process involving losses by absorption and scattering.
Reduction of the disease-producing ability (virulence) of a bacterium or virus by chemical treatment, heating, drying, by growing under adverse conditions, or by passing through another organism. Treated (attenuated) bacteria or viruses are used for many immunizations.
The lessening of virulence. Bacteria and viruses are made less virulent by being heated, dried, treated with chemicals, passed through another organism, or cultured under unfavorable conditions.
The attenuation of pathogenicity, which refers to the weakening of a pathogen’s ability to cause disease, often results in a reduction in its virulence.
When radiation traverses through matter, it undergoes a process called attenuation, wherein the radiation gradually loses energy.
