Most studies on radiation have focused on ionizing radiation. However, they have overlooked non-ionizing radiation in processes such as electromagnetic radiation.
Electromagnetic radiation is the process of giving off energy. This means either sending waves or particles through space.
To distinguish between these two types of radiation, you need to keep the frequency in mind. The greater the frequency, the greater their energy. Waves are vibrations that move through vacuum at the speed of light. They are really outside the human visual realm.
There are types of radiation that are not harmful to living things. These are called non-ionizing radiation. They are not dangerous because they do not break atomic bonds and molecules stay together and form electromagnetic waves.
We are mainly exposed to AM and FM radio waves, microwaves, infrared radiation and ultraviolet radiation.
On the extreme opposite side of the spectrum we find ionizing radiation. These break up atoms and ionize atoms in your cells, causing irreversible damage to humans or even death.
These rays come from unstable atoms in radioactive substances, such as uranium.
The types of radiation
There are mainly three types of radiation: alpha, beta and gamma.
- Alpha (α) : This radiation barely penetrates and can pass through a sheet of paper. This is especially harmful because it means that when it enters a place, it will contaminate food or drink in the area. By simply touching or eating these foods, the radiation breaks up molecules.
- Beta (β) : This type penetrates more than alpha radiation, and can pass through a layer of aluminum. However, it is much less harmful.
- Gamma (γ) : This type of radiation penetrates very deeply, and they come from an atomic source. Thus, thick shields such as concrete are needed to prevent them from passing.
The harmful effects of radiation
Electromagnetic radiation causes biological changes in humans. However, these changes are not necessarily harmful.
For example, when you listen to music, dance or read a book, it is a biological change that does not affect your body. This has the ability to compensate for the effect of the radiation.
However, when your body is exposed to electromagnetic waves and the biological effect exceeds the normal range, it affects your health.
In fact, one of many scientific reports focuses on the effect of electromagnetic waves on the human endocrine system and related diseases.
There have been cases of:
- Breast cancer, leukemia and tumors
- Memory loss
- Brain cancer
- Cardiopulmonary diseases : tachycardia and high blood pressure
- A reduction in red blood cells
At the same time, you may suffer from other, less serious diseases. These include:
- Vision problems: cataracts and vision loss
- Developmental problems in children
- Neurological diseases: mental confusion, irritability
- Joint pain
- Reproductive problems: changes in the menstrual cycle, miscarriages, infertility
How do you reduce electromagnetic radiation?
Large companies do not recognize that home electronics, telephones and computers affect your health. However, studies have shown that it takes 10 or 20 years before the consequences appear.
It is virtually impossible to avoid exposure to electromagnetic radiation. However, you can reduce your exposure by following some tips :
- Turn off and unplug devices that you do not use.
- You need to charge the phone and then disconnect it. If you need to plug it in, keep the plug far away from your body.
- If you use a heater or fan, place it at least three meters away from your bed.
- Do not use electric blankets.
- For your table lamps , it is important that you use incandescent lamps.
- When heating anything in the oven or microwave, stay away from the appliance until the food has finished heating.
- Keep away from your television. It generates electromagnetic radiation.
- Turn off your Bluetooth devices if you do not need to use them.
- Avoid enclosed spaces with air conditioning.
- Do not place the washer and dryer near your living room. The radiation can pass through the wall.
- Reduce cell phone use, especially for children under 14 years of age.
To conclude, humans are exposed to millions of types of good and bad radiation. However, the only thing you can do is try to reduce them by following the advice in this article.
Even if you do not see the problem, it is possible that the consequences will affect your life in a few years.
