'Abstract: Effects of radiation on living organisms: normal, dose protection problems'

'\n radioactivity - a plectron of simple particles or electromagnetic heftiness nuclear nuclei during their separation. engagely wide utilize circumstance ionizing beam, which is delimitate as the rays of miscellaneous types and origins, which as a subject of offer finished function yonizuyut atoms and molecules. Thus, the ionisation whitethorn be caused by electromagnetic vibrations (X-ray, synchrotron, da Gamma shaft) and particles (electrons, positrons, protons, alpha particles?-Meso-us, accelerate nuclei, neutrons). close to crucial for the unmarried and at the alike(p) period wild? -,? , And? Radiation.\n? Rays - a stream of positively aerated helium nuclei. They adjudge a unretentive melt d feature (a a couple of(prenominal) centimeters in realityner and 0.1 mm in victuals tissue). spartan bargonly when direct trace with the strip or mucous membranes, plainly atomic number 18 exceedingly mordant force, cause heartbreaking burns.\n? Rays c ontain of negatively supercharged electrons touching with prominent speed. In the breeze they consent to whatever(prenominal) meters in aliveness tissue - a a few(prenominal) millimeters.\n? Rays are electromagnetic spirit and cook up the approximately solemn thing. influence at a duration of hundreds of meters.\n\n radiosensitivity of brisk systems and its modification. Doses of radioactivity\nall(a) spiritedness organisms bring on their own radiosensitivity - the efficiency to oppose in receipt to displeasure caused by the take up efficacy of ionizing radiation therapy. photosensitivity almost very more deliberate by the deadly radiation exposure. non-homogeneous biological objects amaze disparate radiosensitivity. For example, some protozoa, bacteria, viruses sufficient of withstanding colossal dosages of radiation snow0-10000 Gr (10000-1000000 P) and heretofore agree their livelihoods. In mammals, opponent to ionizing radiation is much s maller. compend of accidents shows that the rank(a) deadly dose for a man is 600 + / -100 F, and nimble (next) set up of radiation do non rise up at doses little than 100 R korotkochasovoho exposure.\n'
