This Is The Danger Of Radiation On The Human Body


Talk about a rarely performed radiation causes still often arise misunderstanding about this. Some people say exposure to radiation in small doses will not affect to the body. But some others say different. How exactly the danger of radiation on the human body?

What is radiation?
Radiation is energy released, either in the form of waves or particles. Based on the electric charge that will be remembered for a certain object after mashing, radiation is divided into ionizing radiation and non-ionic radiation.

Non-ionic radiation might be more often we find around us like radio waves, microwave (microwave), infrared, visible light and ultraviolet light. While the Group of ionizing radiation include x-ray (CT-can), gamma rays, cosmic rays, beta, Alpha and neutron.

Bahay radiation is usually more common types of ionizing radiation, due to its nature that will give the substance electrically charged against objects ditabraknya. This condition usually will exert influence, especially when the object was living beings.

Radiation hazards to humans depends on these factors
The smallest living beings body constituent is cells. When cells interact with ionizing radiation, the energy of the radiation will be absorbed into the cells and was able to lead to changes in the chemical molecule contained the chemical Changes in cells. which can trigger the occurrence of other genetic disorders. The dangers of radiation towards the human body itself varies, depending on:

Sources of radiation
Exposure from cosmic rays usually tend to be ignored, because before it reaches the body of living beings, the radiation had interacting with the Earth's atmosphere.

Neutron radiation is usually only found on nuclear reakton. While the beta radiation is only capable to penetrate the thin paper, as well as with the alpha radiation is only able to penetrate several millimeters. However, x-rays and gamma rays, in addition there are around man, Ray is dangerous if successful memapari beings.

It can also be distinguished by the radiation you receive when you go through an airport body scan machine (which is intensitasnya lower), with radiation you receive when you live near the area that experienced nuclear events, due to the different types of radiasinya.

The large number of bodies received radiadi dose
At low doses, radiation exposure to the body's cells are still able to restore himself in time not so long ago. Damaged cells will just die and are replaced by new cells.

However, in high doses, damaged cells would multiply to become cancer cells (especially when the pattern your life support for exposure to cancer such as smoking behaviour, food consumption vulnerable to carcinogens, and so forth).

Long exposure
Radiation exposure at high doses in one time or short term will also cause some symptoms (acute radiation syndrome called) on your body such as nausea, vomiting, diarrhea, fever, limp to fainting, hair loss, redness, itching swollen, burning, pain feels to to convulsions. This would certainly be different symptoms when you are exposed to in a long time.

Sometimes sensitivity of a person's body also affects the impact of radiation exposure on a person's body. For example, the gamma radiation by as much as 400 brake will cause death to a person when it is dipapari by two different times, with a span of 30 days. However, the same dose in fact will not give any effect when we exposed during one year in smaller doses evenly.
