Gamma radiation.

Few of us are aware of the phenomenon of gamma radiation, since not all of us have a special knowledge in the field of physics.

Thus, the gamma radiation is one of the many varieties of electromagnetic radiation.The wavelength in this case is very small, as its wave properties.History of the discovery of the radiation began more than a hundred years ago.In 1900, this phenomenon was discovered by one of the French physicists - Paul Willard.And there was this discovery quite by accident as a result of the study of radium.

Gamma rays are unique and have a number of unique properties.The basic processes occur in the penetration of the radiation through certain substances.The photoelectric effect of these rays is based on the occurrence of the electrons in the material when exposed to light.The photoelectric effect in this case may be either external or internal.

Compton effect - yet another property of gamma radiation, which also deserves special consideration.In this case, there is an increase of the electromagnetic wave.This phenomenon was discovered in the distant 1923.

Pairing - another unique feature of the gamma rays.As a result, a certain reaction, quantum, located in the center of the nucleus, and becomes an electron and a positron.But due to the effect of nuclear radiation such gamma ray is able to beat out of the nucleus nucleons.Gamma radiation in the world today is used in many different areas of human life.Gamma flaw detectors, for example, allows you to monitor the work of many devices and products with special rays.Preserving many products also takes place using similar beams.Thus the shelf life of blanks is significantly increased, and about any harmful effects and is not out of the question.

Using gamma radiation sterilization processes carried equipment, medical instruments, some food.In medicine, these rays are also found the area of ​​application.With radiation therapy, for example, a huge number of species treated tumors.Agree, this is an important contribution to the development of medicine, since it is far from each drug.When using gamma rays, we are seeing quite good results in the treatment of cancer and also at relatively low cost.And in general, gamma rays due to their specific properties could significantly advance medicine forward.

Gamma Ray is an integral part of geology.Using various sources of gamma radiation, geologists measure the depth of wells.But gamma-altimeter - a way to accurately determine the distance traveled by the spacecraft.That is, the active use of radiation found in space exploration and geology, and medicine, and industry.But with all these positive aspects of gamma radiation has some drawbacks, which need to be sure to know.Because of prolonged contact with the rays, for example, there is a dangerous disease - radiation sickness.The most serious consequence of such exposure are various types of cancer diseases.

In addition, these rays are also teratogenic effects on the body, which results in a mutation and the disruption of normal embryonic development.In fact, the gamma rays - it's the same radiation, of which we have heard a lot, but about which little is known.Although the correct use in small doses using modern equipment emission data can greatly facilitate and enhance human activity!
