Radon

Radon (Rn) - a radioactive element of the zero group of the periodic system of Mendeleev, serial number 86, the inert gas. Most important are its alpha-emitting isotopes: Rn222 (Radon, radon former name) with a half life of 3.8 days and Rn220 (thoron), with a half life of 54.5 seconds. Decaying, Rn222 Rn220 and give rise to a group of short-lived isotopes (radon progeny and thoron). Rn222 contained in the ambient air and soil, in natural waters and natural objects containing radium. Rn222 widely used in clinical practice (see Alpha-therapy). Presence Rn222 Rn220 and their daughter products (the Read more [...]

Radioprotective

Radioprotective (synonym radioprotective drugs) - a chemical compound used to reduce the harmful effects of ionizing radiation on the body. Radioprotectors used only to prevent and alleviate the course of radiation sickness. Introduction radioprotectors after irradiation is ineffective. Conditionally radioprotectors can be divided into two groups: 1) short-term radioprotective, simultaneous actions, which are injected into the body for a short time before the exposure, and 2) radioprotective depot, which is administered repeatedly, usually in small doses to radiation exposure. By radioprotectors Read more [...]

Radionuclide Diagnostics

Isotope diagnosis and differential diagnosis of malignant and benign breast processes carried out mainly through contact with radiometry 32P. Methodology of the study. Drug (dibasic sodium phosphate) is administered on an empty stomach into the rate of 1 mCi / kg. Diagnostic examination beta scintillation probe with a set of collimators produce 24, 48 and 72 h after administration of phosphorus. Isotope concentration in symmetrical nidus healthy breast is taken as 100%. Then, in the same way produce radiometry of each point of the affected gland (at least 3 times for 1 min at each point).

Radionuclide Diagnostics

Radionuclide Diagnostics - Is to recognize diseases with compounds labeled with radioactive isotopes. There are four methods of radioisotope diagnosis: radiometry laboratory, clinical radiometry, clinical radiography, scanning. To implement them, labeled connection injected into the patient's body through the mouth or directly into the blood, and then the radiometric or radiographic studies. In laboratory radiometry examine individual portions of blood, urine or feces in special kolodtsevyh houses to determine the content of the labeled compound. Most often, this method used to determine Read more [...]

Radiobiology

Radiobiology - Section of Radiology, the student action ionizing radiation on living organisms. Radiobiology establishes the dependence of reactions from a number of physical and biological factors - the type of radiation exposure, the dose of radiation (see Dose Ionizing Radiation), the factor of time of exposure (see exposure), radiosensitivity (see), the body, etc. Radiobiology explores how the transfer ionizing radiation energy living matter which primary physical and chemical processes, and biochemical effects are there and what the morphological and functional changes they cause (see radiation Read more [...]

Gray groundhog — marmota baibacina kastsch. The practical significance

Gray marmot - A valuable trade animal, skins which are in great demand in the foreign and domestic markets. They are used (usually painted) on the collars, hats, coats, and to simulate a valuable furs, such as under a sable. Everywhere the people appreciated the fat marmot, especially in the fall, which has a good taste and medicinal properties against tuberculosis, anemia and severe injuries. Since 1966 began, centralized procurement of fat. Marmot meat fall quite tasty, but in Kazakhstan, used for human consumption is still relatively low. Quality skins adults and young animals in the autumn, Read more [...]

Radioactive drugs-1

Pages: 1 2Plastics containing radioactive drugs called beta-applicators, apply only to overlay the skin of the patient. They provide a source of beta radiation - strontium-90 (see Strontium), thallium-205 and P-32 (see Phosphorus radioactive), Which are evenly distributed throughout the applicator. Unlike other radioactive drugs, specific activity beta applicators is not expressed in units of mc, and in terms of dose rate on the surface (P / h). Bending plastic or in contact with moist skin radioactive substances partially fall out and can lead to radioactive contamination. To avoid this, Read more [...]

Radioactive drugs

Distinguish radioactive drugs for biomedical research, diagnostic, medical and radiation sources for gamma-devices. In biomedical research can be applied to hundreds of inorganic and organic compounds labeled with 14C, 3H, 32P, 35S, 131J and other radioactive isotopes. The most important are labeled amino acids and their analogs and derivatives, alkaloids, vitamins, antibiotics, carbohydrates and their derivatives, components of nucleic acids, steroids and steroid hormones. For tagging diagnostic RP, as a rule, use of radioactive isotopes (see) with a short half-life. In the case of long-lived Read more [...]

Radioactive waste-1

Coming into the atmosphere of radioactive aerosols, depending on the terms of issue (the height of pipes, etc.) are more or less radioactive drugs scattered intensity, but eventually deposited on the surface of the earth. When uncontrolled removal radioactive waste, and in the case of accidents are possible contamination of the surrounding area. This creates the conditions for the migration of radioactive isotopes in the chain plant - animal - man. A characteristic example is the intake of radioactive iodine. It is also possible the direct flow of radioactive aerosols into the body by inhalation. Read more [...]

Fallout

Fallout - precipitated from the atmosphere, radioactive aerosols arising from nuclear weapons tests. Fallout distinguished: local, tropospheric and stratospheric. Local R. o. are large, mostly melted particles that fall under the force of gravity close to the explosion site. Basic sanitation is defined as the value of their gamma-ray sources. Tropospheric fallout - radioactive particles of micron and submicron size, coming from a nuclear explosion in the troposphere. Over 2-6 weeks, they are carried by air currents around the globe, gradually deposited on the earth's surface. They contain Read more [...]

Radioactivity

Radioactivity - the ability of certain isotopes of atoms spontaneously decay by emitting radiation. For the first time this type of radiation emitted by uranium, Becquerel discovered, so first radioactive radiation called the Becquerel rays. Main type of radioactive decay - ejection from the nucleus of an alpha particle - alpha decay (see Alpha radiation) or beta particles - beta decay (see Beta radiation). The radioactive decay of the original atom into a atom another element. As a result of ejection from the nucleus of an atom of an alpha particle, which is a combination of two protons and Read more [...]

Radiculitis - Disease of spinal roots. Radiculitis distinguish primary (infectious, toxic) and secondary, often associated with the pathology of the spine and spinal cord. There are also meningoradiculitis - an infectious disease spread from the roots of the pathological process in the membrane spinal cord occurs in rheumatism, brucellosis, syphilis, and shows multiple lesions of roots and meningeal symptoms. Secondary radiculitis may be due to neuromas roots, spinal tumors, tuberculous spondylitis, osteomyelitis, osteochondrosis, traumatic spinal injury.

Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
