Ten Types of Radiation we Receive Daily – Part-2
We all face risks in everyday life. It is impossible to eliminate them all, but you can reduce them.
The use of radiation and nuclear techniques in medicine, industry, agriculture, energy and other fields of science and technology have brought enormous benefits to society.
No human activity is completely without the associated risks. The radiation should be viewed from the point of the amount of benefits brought to humanity are less harmful than many other actors.
Radon is a radioactive gas produced by the decay of uranium in rocks and soil. As uranium decays, radon is being produced and seeping into the buildings, their accumulation may create a health hazard.More than half of our exposure to radiation from radon , snuff consumption only causes more lung cancer cases.
The EPA estimates that about one in every 15 homes has elevated radon levels. There are professionals who can go home and check the air, then advise you on what action to take. You can also buy a kit and test it yourself.
The most common way of eliminating the radon which is filtered in a home is to install a system of active soil depressurization , which is a tube with a fan which aerates the radon from beneath the house. The professional should also seal all entry points to prevent radon in your home brew.
3. Medical-dental Exhibition
For decades, doctors have used all alphabet soup ( MRI , CT and PET among others) scans to find irregularities. In nuclear medicine use small amounts of radioactive isotopes to detect abnormalities of organ systems. Besides the use of X-rays.
Although none of these tests have enough radioactivity to pose a threat , many people are concerned about the cumulative exposure over a lifetime of medical care.
Some experts advise patients to make sure to use a lead shield on the chest and neck when taking dental radiographs. You can also ask your doctor or dentist if X-ray scans are really necessary or if the period of time between them could be higher.
More serious are the treatments for diseases like cancer. Therapeutic radiation treatments for cancer are different from low-dose treatments and can cause permanent damage, but damage is still minor compared to what will happen if it is not cancer. Patients treated with radiation are radioactive for a while and should be kept away from other people.
2. Cosmic Radiation
Like characters in a science fiction movie, we are constantly bombarded by cosmic radiation. About 8 percent of our annual dose of radiation from outer space.
Subatomic particles from the Sun, our galaxy and even more distant galaxies are mixed with the atmosphere of the Earth to create radiation. Most of this energy cosmic radiation is low, however, part of this radiation passes through us and interacts with our bodies , but in such low doses that do not harm.
The atmosphere protects us from cosmic radiation, but the higher the altitude, the greater the radiation to which we are exposed. If you live in Avila will receive a little more cosmic radiation than someone who lives in San Juan de Alicante, but the difference is tiny.
The same principle applies to airline flights. The amount of radiation that is absorbed into a flight is only half of that recibiríais on a chest radiograph.
1. The Earth itself
Radiation is nothing new, no creation that humans invented during the last century industrialization. It has always been with us and even within us. In fact, the Earth itself generates much of the radiation to which we are exposed .
All types of radioactive materials occur in the ground beneath our feet. These natural sources of radiation can leave the ground for us to inhale its particles. Our muscles, organs and bones are radioactive to some degree.
Humans also take this radiation transmitted by the soil, by eating produce grown on land or water from underground wells.
