Pilots, cabin crew, and astronauts are at more risk of higher doses because of the increased exposure to cosmic rays at altitude. Because bones are rich in calcium, which has a high atomic number, the X -rays are absorbed and appear white on the resulting image.
Computed tomography (CT): The patient lies on a table and enters a ring-shaped scanner. The patient moves slowly into the machine so that a series of “slices” can be taken to build up a 3D image.
However, X -rays provide such a low dose of radiation that they are not believed to cause any immediate health problems. The fact that X -rays have been used in medicine for such a significant length of time shows how beneficial they are considered to be.
The authors go on to point out that despite being bombarded by cosmic rays and background radiation, the people of America are living longer than ever, partly because of advancements in medical imaging, such as the CT scan. Updated: Jul 4, 2013, 09:10 PM IST No matter how important x -rays are medically, they have their side effects like any other form of radiation.
Due to their relatively smaller physical size, children are more sensitive to the radiation as it could badly affect their genitals. Reports say that when exposed to x -rays, especially in the lower abdominal region, a person is at the risk of developing genetic damage that could turn hereditary.
To be afraid of the natural radiological background is not worth it: research of the late 20th century showed that living organisms even need to receive radiation dose in their habitat. If it is artificially reduced, this leads to a slowdown in the growth and development of living organisms.
In addition, to exclude the radiation of microwaves outside the furnace, it has different types of protection: the glass of the door is necessarily screened with a frequent metal mesh, the metal chamber of the furnace is closed by the front door. In recent years, thanks to the appearance of digital devices, the dose has been reduced to 0.04 MTV.
To the development of radiation sickness the dose is thousands of times higher than from these procedures: 1 SV. There are no maximum doses in medicine: if the procedure is necessary and the health benefits will be greater than the harm, it should be carried out.
However, there is a recommended level: according to sanitary rules and norms (entered into force in 2009), the average effective dose of radiation from medical diagnostic examinations per year should not exceed 1 MTV. In the United States, the effective dose of medical diagnostic procedures is significantly higher: about 3 MTV.
According to the recommendations of the American College of Obstetricians and Gynecologists (COG), the radiation that the patient receives from radiography or CT is much lower than the level considered dangerous for the fetus: above 50 may (milligray). According to studies of recent decades, the risks of stimulating the development of malignant cells in children increase with a dose of 50-100 MTV.
While meningiomas are not cancerous, they can cause stroke-like symptoms including seizures, headaches, and problems with vision, speech and motor control. Mammograms sometimes lead to false positive results, leaving a woman thinking she has cancer when she actually does not.
Filed Under: General Health Written By: Jesse Cannon, CFT, CARS, MFT Updated: December 5,2012 What makes X -rays very dangerous to the health is the radiation which they are basically made up of.
While X -rays can be useful in diagnosing and treating so many illnesses, too much exposure to it can be extremely dangerous to our health. According to scientists, exposure to X -rays can easily damage our delicate cells and tissues.
Scientists say that constantly exposing yourself to X -rays can easily cause you to suffer from cancer. And as we might all know, constant exposure to radiation will destroy our cells and tissues, and that action alone increases our risk of developing cancer.
Another danger of too much exposure to X -rays is the fact that it can easily lead to leukemia. According to scientists, one increases his or her chance of suffering from leukemia when they keep exposing themselves to X -rays.
Studies have found out that X -rays can lead to a mutation of living cells. The reason this is possible is simply because when one is exposed to X -rays, the powerful radiation tends to ionize the fluid in the body and result in chemical changes.
Given the importance of this diagnostic tool, it is vital that you take a closer look at this machine and understand some of its positive and negative effects. Primarily, they are a naturally occurring source of electromagnetic radiation and doctor’s use films to image them, when these high energy particles collide with the patient’s bones and muscular structure.
In fact, thanks to x -rays, doctors, in general, have been able to make an effective diagnosis that ended up saving the patient’s life. This is one of the reasons why only low dosages of x -rays are used for diagnostics, but even so, depending on the medical procedure and the imaging performed, the risks of developing cancer and having the cells in your body damaged permanently remains high.
It should be pointed out that even as both WHO and US government have declared x -rays to be carcinogenic, the dosages used in most medical procedures are extremely low, at best. This can result in you exhibiting various symptoms such as hair falling, diarrhea, skin rashes, changes to DNA, mutations and even cancer.
If you just had your head examined with x -rays, then chances are high that you would develop a case of dry mouth and may even have trouble swallowing. These are some positive and negative effects of x -rays; it Is true that your bones will absorb the radiation and regular exposure to the same will cause them to become brittle over time.
Thanks to the various advancements made in medical science, especially in x -rays, doctors can now evaluate their patients by reviewing their x -rays in 3D. This allows them to check out the patient in more detail and enables them to review some underlying health conditions and to treat them for the same.
