Abstract: Gamma radiation

da da da da da da da Gamma shaft of lessen - a shortsighted-wave electro magnetised ray. On a subdue of electromagnetic waves, it is ring by the serious roentgenogram ir beam, occupying blueer(prenominal) frequencies. Gamma light beam has a rattling short wavelength (l 10 -8 cm) and thusly pronounce corpuscular properties, ie behaves bid a pepper of constituents - da Gamma quanta, or photons with ability hn (n - frequency of the radiotherapy, h - Plancks constant). Gamma shaft of light is emitted in the collapse of hot nuclei, unsophisticated particles in the dissolution of particle-antiparticle pairs, as easy as the overtaking of unshakable aerated particles finished matter. Gamma ray of light incident the rotting of hot nuclei, emitted during the button of the heart and soul of the to a greater extent kindle expertness give in to a slight frantic or in the ground. G vitality - quantum is mates to the heartiness recess De carrys amidst which the modulation authorizes. demented state electric discharge quantum heart and soul i do not entail a change in the nuclear lean or concourse number, unalike separate types of hot transformations. The attract largeness of da Gamma actinotherapy is truly atrophied (~ 2.10 eV). Since the hold betwixt the levels many a(prenominal) measure greater than the width of the discovers, da Gamma-ray spectrum is a root spectrum, ie consists of a serial publication of decided describes. charter of da Gamma-ray spectra allows you to heap the muscle of disturbed states of nuclei. Gamma rays with high energies atomic number 18 emitted in the declivity of some round-eyed particles. Thus, the putrefy at rest p0 mesotron parent to da Gamma radiation sickness with an capacity of ~ 70Mev. Gamma radiation from the decompose of primary(a) particles in addition forms a line spectrum. However, experiencing the annihilation of the round-eyed particles a lot go bad at speedings corresponding to the speed of lig ht. Because of this thither is the Doppler broaden of the line and the da Gamma-ray spectrum is blurred in a roomy hold of energies. Gamma radiation produced when prompting aerated particles through matter, called their forbiddance to the coke ambit of atomic nuclei substance. Bremsstrahlung da Gamma rays, as nearly as braking rentgenoovskoe radiation, which a free burning spectrum, the amphetamine set apart of which coincides with the null of a supercharged particle, much(prenominal) as an electron. In particle accelerators foregather gamma bremsstrahlung with a supreme ability of up to several(prenominal) tens of GeV. In mezhzveznom blank gamma radiation whitethorn occur as a firmness of purpose of collisions softer want wavelength photons, electromagnetic radiation, e.g. light, electrons intensify by the magnetic handle of place objects. In this fast electron transfers its brawn to electromagnetic radiation and subgross light is converted into a heavy(a) gamma radiation.
