RADON WATERS — the radioactive mineral waters enriched with radon.

In the USSR lower limit of concentration of radon for reference of waters to radonic 5 nkyuri/l, abroad — 10 nkyuri/l. Carry to radonic also waters with the smaller content of radon (e.g., Tsqaltubo waters) if they have temperature, optimum for treatment, and a big output that allows to apply them in flowing bathtubs and pools without heating.

On concentration in a domestic balneoterapiya allocate the following kinds of radon waters: very slaboradonovy (5 — 20 nkyuri/l), slaboradonovy (20,1 — 40 nkyuri/l), radonic average concentration (40,1 — 80 nkyuri/l), high-radonic (80,1 — 120 nkyuri/l), very high-radonic (more than 120,1 nkyuri/l). Rubles of century distinguish on chemical composition: oxygen-nitrogen, low-mineralized, cold (A lime-vat — the content of radon 22 nkyuri/l; Uvilda — the content of radon 473 nkyuri/l, etc.); nitric, siliceous, low-mineralized, alkaline, thermal (Belokurikha — the content of radon 7 — 25 nkyuri/l; Tsqaltubo — the content of radon 0,8 — 5,5 nkyuri/l, etc.); nitric, srednemineralizovanny thermal (Dzhety-Oguz content of radon 91 — 127 nkyuri/l); nitric, cold brines (Ust Kut — soderyashny radon 26 nkyuri/l); carbonic, a part siliceous various ionic structure, a mineralization and temperature (Molokovka — the content of radon 18 — 70 nkyuri/l; Pyatigorsk — the content of radon 29 nkyuri/l).

In the USSR there are about 30 radonic resorts. They are located in areas of fields of radon waters — in mountain (Transbaikalia, Tuva, Altai, the Urals, the Caucasus, etc.) and flat areas with large arrays of izverzhenny breeds (Karelia, Ukraine). Abroad apprx. 300 radonic resorts, from them 130 in Japan.

Along with natural R. century are used as well artificial which receive, adding strong solution of the radon prepared in specialized radonic laboratory to water. In the USSR works apprx. 250 radonic laboratories.

Radonoterappya (a kind of an alpha therapy) — one of types of radiation therapy with use of very small doses of radiation. The major operating factor is the alpha radiation of radon (see. Alpha radiation ) and its temporary affiliated products (radium A and radium C). At treatment radonic bathtubs generally irradiate skin, at R.'s drink of century — digestive organs, at radonic inhalations — a respiratory organs.

Stimulation of protective and recovery functions and immunnobiologichesky reactivity of an organism is the cornerstone of action of a radonoterapiya. It has the analgeziruyushchy, antiinflammatory and hyposensibilizing effect.

Radonic bathtubs (see) render the action at first narrowing, and then expanding on capillaries of skin, contributing to normalization of the ABP and cardiac performance; improve composition of red and especially white blood; normalize activity of a thyroid gland and ovaries at their hyperfunction. R.'s drink of century and radonic bathtubs normalize motor and secretory function went. - kish. path. R.'s drink of century, radonic bathtubs and inhalations normalize standard metabolism, function of a hypophysis and adrenal glands. On c. N of page radonic procedures reflex have the expressed sedative effect, on peripheral — soothing. Along with the mediated systemic effect through the centers of neuroendocrinal regulation the local promoting effect of alpha radiation of radon and its affiliated products on regeneration of various fabrics is established (see. Alpha therapy , Balneoterapiya ).

Indications: diseases of cardiovascular system (idiopathic hypertensia of the I—II And stages, heart diseases); diseases of a musculoskeletal system (bones, joints, backbone, sinews, etc.); diseases and effects of injuries of the central and peripheral nervous system (neurosises, myelosyringosis. initial forms of atherosclerosis of vessels of a brain, etc.); diseases of generative organs (chronic inflammatory processes of a uterus and appendages with the expressed pain syndrome and disturbance of menstrual function in combination with a hysteromyoma when its sizes it is no more than at 12 not of of pregnancy; infertility, chronic inflammatory processes of men's generative organs); disturbance of exchange (a diabetes mellitus at an easy current and moderately severe, obesity, gout); hyperfunction of a thyroid gland of easy and average degree; diseases of the digestive system (peptic ulcer of a stomach and duodenum, chronic inflammatory diseases of a liver and bilious ways); hron, diseases of skin.

Contraindications — see. Balneoterapiya . Sanatorium selection .

Rubles of century are applied to bathtubs, bathings, irrigations, drink and inhalations. Radonic bathtubs and ginekol are most widespread. irrigations. Radonic baths are taken in the separate cabins equipped with positive-pressure ventilation with 8-fold air exchange in an hour. For radonic bathtubs, bathings and ginekol. irrigations apply usually R. century with concentration of radon 40 — 80, is more rare 120 nkyuri/l and above (natural R.' concentration of century can be below) at t ° 34 — 37 °. Duration of the procedure 5 — 20 min. At treatment of children the content of radon in water shall be not higher than 40 nkyuri/l. A dose of radon on a course of drinking treatment — 72 mkkyur (1 — 3 mkkyur a day).

In some resorts use the radon extracted from water for air-radon bathtubs (concentration 10 — 40 nkyuri/l, duration of the procedure 15 — 20 min.) and for radonic inhalations (concentration from 1,0 to 40 nkyuri/l). The course of treatment at any route of administration of R. of century includes 12 — 15 procedures.
