英语释义

1. a theoretical phenomenon of dose-response relationships in which something (as a heavy metal or ionizing radiation) that produces harmful biological effects at moderate to high doses may produce beneficial effects at low doses
Others argue that tiny doses of radiation are not harmful. Some scientists even claim that low doses, by stimulating DNA repair, make you healthier—an effect known as hormesis.

radiation hormesisRadiation hormesis (also called radiation homeostasis) is the hypothesis that low doses of ionizing radiation (within the region of and just above natural background levels) are beneficial, stimulating the activation of repair mechanisms that protect against disease, that are not activated in absence of ionizing radiatio The reserve repair mechanisms are hypothesized to be sufficiently effective when stimulated as to not only cancel the detrimental effects of ionizing radiation but also inhibit disease not related to radiation exposure (see hormesis).

英汉例句

• hormesis is that decreased risk of adverse effects would occur with increased dose levels when subjects are exposed to toxin at low levels.

  毒物兴奋效应是指在较低药物剂量水平时，随着剂量水平的增加，受试者对药物的不良反应降低。

• there were significant concentrations and timing differences in the hormesis induced by organophosphorus pesticides in microalgae.
