irradiation

• Substantivo que designa a exposição a radiação ou um feixe de luz. Em fisiologia, a propagação de impulsos nervosos sensoriais pelo córtex cerebral. Em óptica, o aparente aumento de um objeto claro sobre fundo escuro. No condicionamento pavloviano, a eliciação de uma resposta condicionada por um estímulo semelhante, mas não idêntico. Em medicina, o tratamento de doenças, especialmente câncer, por exposição a substância radioativa.

A noun referring to the condition of being exposed to radiation, or a column of light. In physiology, it denotes the spread of sensory neural impulses in the cortex. In optics, it describes the apparent enlargement of a bright object against a dark background. In Pavlovian conditioning, it is the elicitation of a conditioned response by a similar but not identical stimulus. In medicine, it refers to the treatment of disease, especially cancer, by exposure to a radioactive substance.
