Beta-therapy (β-particle - a charged particle emitted as a result of beta-decay; therapy from the Greek therapeia - care, treatment) is a form of radiation therapy based on the effect of beta-radiation of radioactive isotopes on pathologically altered tissues.
Beta therapy types:
Application - in which beta applicators are placed on the surface of the mucous membranes or skin, which effect emitting isotopes;
Intracavitary - in which colloidal solutions of radioactive isotopes are injected into the natural cavities of the body;
Interstitial - in which the introduction of radioactive isotopes is carried out by impregnating tissues with their colloidal solutions, implanting granules, films or threads impregnated (saturated) with isotopes into the tissue, or using the ability of some tissues to selectively absorb certain elements after their parenteral or oral administration.

Adrenergic receptors (lat.adrenalis - adrenal; lat.ad- - at + ren - kidney + receptor - receiving; synonym: adrenergic receptors, adrenoreactive structures, adrenoreactive systems) - biochemical structures of cells that interact with adrenergic mediators (dopamine, adrenaline, noradrenaline ) and convert the energy of this interaction into the energy of a specific effect (muscle contraction, nerve impulse)
