X-Ray Dangers



X Rays are not the harmless, miraculous health "helps" we used to think they were. Instead, X Rays are something many people will want to avoid unless absolutely necessary. X Rays are not the best diagnostic tool for all things.
How much radiation does a person receive in an average dental X Ray? Here's a comparison, measured in millirems; the standard measure of radiation absorption by human cells:


IN MILLIREMS
Flight from Los Angeles to Paris (cosmic rays) 4.8 Millirems.

Chest X Ray (l film) 6-30 Millirems.

Contamination 1/2 mile from Three Mile Island during nuclear accident 83.0 Millirems.

Apollo X astronauts on moon flight (cosmic rays) 480.0 Millirems.

Dental X-ray (whole mouth) 25-36 Millirems.

On-site dose at Three Mile Island accident 1100.0 Millirems.

Breast mammography (1 film) 1500.0 Millirems.

Current N.A.S. yearly occupational exposure accumulative limit is 5000.0 Millirems.

It becomes questionable whether each visit to a docter/dentist should be almost the equivalent of visiting a nuclear power plant during an "accident," or if it should "use up" almost one-fifth of what the N.A.S. considers a yearly maximum for folks working around radiation.


Exposure to x-rays leads to leukemia and other cancers.

Long-term exposure to even small levels of x-rays may be hazardous. X-ray radiation is "ionizing" which means that it can create harmful free-radical chemicals in the body. These chemicals can mutate DNA which can result in cancerous cells. X-rays are photons. X-ray radiation is not a persistent radiation. That means that once the power is off the x-rays are gone. X-rays cannot cause other objects to become radioactive. It kills the heart and the blood vessels.


As far as the human body is concerned there are three systems, which are affected by x-rays. First, is the genitalia, which if affected may have a negative effect on the progeny. The other main system that is affected is the skin. You can get a rash, hair loss and apart from being cosmetically harmful, they also predispose to cancer. The third system that is affected is the blood. If the red blood cells are affected, then you can suffer from anaemia and if the white blood cells are affected, they can attack your immune system and make you vulnerable to various diseases.


Ionizing Radiation: dislocates electrons/atoms




H2O + radiation -> H2O+ + e- : OH, H+, H, OH-, H2O2


Early cell death
Inhibited cell division
Genetic modification of chromosomes


The Risks to a Fetus from X-rays

Fetuses are more susceptable than adults to the damaging effects of x-rays, partly because their cells are rapidly dividing and growing into specialized cells and tissues. If x-rays cause changes in these cells, there is a slightly increased chance of birth defects or certain illnesses, such as leukemia, later in life. However, most birth defects and childhood diseases are not attributed to exposure to any known harmful agent during pregnancy.

Damage to fetal cells may result in miscarriage, birth defects, or mental impairment, depending on the amount of radiation and the stage of pregnancy. The risks are higher during the first three months of pregnancy (first trimester). It is important to note that most of these effects do not usually occur below 100 mGy - more radiation than three pelvic CT scans or 20 abdominal x-rays.

There is an increased risk of childhood cancer from DNA damage regardless of when in pregnancy the radiation occurred. The risk is believed to be proportional to the amount of radiation, i.e. the smaller the amount of radiation, the smaller the risk of cancer. Most studies show no increase in childhood cancer from small amounts of radiation. However, one study identifies the chance of a childhood cancer from abdominal x-rays (in the 10 mGy range) at about one in 1,000 births. In comparison, the chance of a childhood cancer in the general population is about two to three in 1,000 births.

No, they will not, the x-ray machine does not put out enough radiation material to damage lab tops or digital cameras memory cards, they are both magnetically stored so causes no damage to them. Neither will the gift card be damaged, but if you don’t feel comfortable with the gift card going thru the x-ray you could have it hand checked. You will even be asked if you haven’t done before hand to remove your lab top from it’s casing. I see people have stated that film will be damaged which is true, but only if 800 mm or above. Film under 800 will not be damaged, but again if not comfortable you can ask for a hand check. Don’t worry none of your items will be damaged, I fly a lot and am also the x-ray operator who checks your property thru that x-ray your so worried about.

While some cells are damaged by X-rays, your body suffers thousands of times more insults to cells from environmental conditions and other things every day.

Don't worry about a few diagnostic x rays, they save peoples lives every day.

The laptop I know will be fine. Positive. I have put many laptops through the airport scanners. Just put it in one of those basket things, and you're good to go! They'll probably have you take it out The SD Flash memory card should be fine, too, but I would make sure they are backed up somewhere. The only one I worry about is the gift card, knowing that the magnetic things at Target® deactivate the magnetic stripe at times. Best of luck with your trip! :)

well if it did I would be dead by now...lol. I probably have had an xray a month since I have been alive and I am 23.
