There are lots of misunderstanding out there about radiation. Some people believe that radiation takes bad effect to people body and nope rest. So, what is the effect of the radiation to the human body?


First of all, we need to know "What is the radiation?"

Radiation is the energy released, both in the form of waves and particles. Based on the electrical charge that will be generated after mashing a certain object, the radiation is divided into ionizing radiation and non-ionizing radiation.

Non-ionic radiation may be more often encountered around us such as radio waves, microwaves (microwave), infrared, visible light and ultraviolet light. While the ion radiation groups include X-rays (CTs), gamma rays, cosmic rays, beta, alpha and neutrons.

The danger of radiation is usually commonly found in ionizing radiation types, due to its nature which will give electrically charged substances to the object it has hit. This condition will usually have an effect, especially if the object is a living thing.

The danger of radiation to humans depends on this factor

The smallest living organism is the cell. When a cell interacts with ion radiation, energy from radiation is absorbed into the cell and is capable of causing chemical changes to the molecules contained in the cell. It is these chemical changes that can trigger other genetic disorders. The dangers of radiation to the human body itself vary, depending on:

Radiation source

The exposure that comes from cosmic rays usually tends to be neglected, because before reaching the living organism, the radiation has already interacted with the earth's atmosphere.

Neutron radiation is usually found only in nuclear reactors. While the beta radiation is only able to penetrate the paper thin, as well as alpha radiation is only able to penetrate several millimeters of air. However, X-rays and gamma rays, other than in the vicinity of humans, these rays are dangerous if successful reach living thing.

It can also be distinguished from the radiation you receive as you go through the airport's lower-body scan machine (with a lower intensity), with the radiation you receive when you live near a nuclear event, because of the different types of radiation.

The amount of radiation dose received by the body

At low doses, cells exposed to radiation are still capable of recovering themselves in the not-too-distant future. The damaged cell will simply die and be replaced by a new cell.

But at high doses, damaged cells will multiply to become cancer cells (especially if your lifestyle supports to exposure to cancer such as smoking behavior, carcinogen-susceptible food consumption, and so on).

Duration of exposure

Exposure to high doses of radiation at one time or short term will also cause some symptoms (called acute radiation syndrome) on your body such as nausea, vomiting, diarrhea, fever, fatigue, fainting, hair loss, reddened skin, itching, Burning, pain until convulsions. These symptoms will certainly be different if you are exposed for a long time.

Sometimes the sensitivity of one's body also affects the impact of radiation exposure on a person's body. For example, 400 brake gamma radiation will cause death to a person when exposed for two different times, with a span of 30 days. However, the same doses will not even have any effect if we are exposed for a year in smaller evenly distributed doses.
