In children radiation can slow or even stop growth and development. However, these effects require very large doses, such as might be encountered from a nuclear accident or war, and will never be seen in ordinary life.The National Council on Radiation Protection estimates that every American, on average, receives approximately 3 mSv from unavoidable natural environmental sources, with man-made radiation adding about 0.6 mSv on average, mostly from diagnostic exposure in the healing arts. Diagnostic exposures range from the equivalent of a few hours or days (chest x ray or dental bitewings) up to a few years (body CT scan, some nuclear medicine procedures) of this natural environmental exposure.
Source Source: Adapted from Frederiksen NL. X-Rays: What is the Risk? Texas Dental Journal. 1995;112(2):68-72.
Estimated Exposure (mSV*)
Dental radiographs
Bitewings (4 films) 0.038
Full-mouth series (about 19 films) 0.150
Medical radiographs
Lower GI series 4.060
Upper GI series 2.440
Chest 0.080
Average radiation from outer space In Denver, CO (per year) 0.510
Average radiation in the U.S. from Natural sources (per year) 3.000
Medical x-rays have increased the ability to detect disease or injury early enough for a medical problem to be managed, treated, or cured. When applied and performed appropriately, these procedures can improve health and may even save a person’s life.
X-ray energy also has a small potential to harm living tissue. The most significant risks are:
* a small increase in the possibility that a person exposed to x-rays will develop cancer later in life; and
* cataracts and skin burns only at very high levels of radiation exposure and in only very few procedures.
The risk of developing cancer from radiation exposure is generally small, and it depends on at least three factors—the amount of radiation dose, the age at exposure, and the sex of the person exposed:
* The lifetime risk of cancer increases the larger the dose and the more x-ray exams a patient undergoes.
* The lifetime risk of cancer is larger for a patient who received x-rays at a younger age than for one who receives them at an older age.
* Women are at a somewhat higher lifetime risk than men for developing radiation-associated cancer after receiving the same exposures at the same ages.

The amount of radiation used to produce a conventional X-ray image is extremely small and has not been proven to cause harmful effects to children or adults.

"Radiation effects on children are quite similar to those on adults with one major exception: in children radiation can slow or even stop growth and development. However, these effects require very large doses, such as might be encountered from a nuclear accident or war, and will never be seen in ordinary life. The National Council on Radiation Protection estimates that every American, on average, receives approximately 3 mSv from unavoidable natural environmental sources, with man-made radiation adding about 0.6 mSv on average, mostly from diagnostic exposure in the healing arts. Diagnostic exposures range from the equivalent of a few hours or days (chest x ray or dental bitewings) up to a few years (body CT scan, some nuclear medicine procedures) of this natural environmental exposure. All expert bodies and authorities recommend that clinically justified radiologic procedures be carried out without fear of radiation response. Of course, this implies due care on the part of the radiologist in minimizing radiation exposure to the patient. Harmful effects to patients from these diagnostic exposures have not been scientifically proven. If any effects occur, they are either too small or too rare to detect. In any event, health benefits to the patient far outweigh any potential harmful effects. Conclusion: You should accept any recommended diagnostic procedure from your physician, dentist, etc., provided that appropriate justification for that procedure can be presented. S.

The potential for damage is that when the X-rays interact for example with the genetic material in our cells' nuclei, they can damage the chromosomes there. Our bodies have evolved to handle some level of such damage, since there are natural sources of radiation in our environment that can cause similar damage.
When the dose of radiation (X-rays in this case) is not significantly higher than that caused by the natural environment, there is only a low likelihood of the damage causing health problems. Modern X-ray machines are designed to use the minimal dose necessary to form a usable image. The risks due to X-ray imaging is thus minimal unless you are subjected to a very large number of exposures. Radiologists are trained to assess when the risk from the added dose is low enough compared to the medical risks of not having the imaging done.
For children the risks are somewhat higher since, in simplistic terms, their bodies are still developing, so their DNA is being used more than in adult bodies. Still, the risks are relatively low if the number of X-ray images is not especially high, and the imaging is localized to where it is required (e.g. leg only, for a broken leg bone).
For adults, the area most susceptible to radiation damage is our reproductive organs (i.e. gonads and ovaries), which is why those areas are usually shielded with lead-lined aprons when X-ray images are being taken.

M$they work by passing radiation through your body, which your bones will reflect back, letting you see the damage done.
this radiation is harmful, but only in high amounts.
x-rays are harming children, but its only noticeable in excess amounts.
in summary, dont stop your child having x-rays if they are needed, but dont let them get x-ray'd for every little pain, as it WILL damage they're body.

X-rays are done when the advantages of diagnosis is more than the risks.

The Xrays have bad effects on pregnancy and childbirth. The birth defects can deform the body of the infant and could be fatal to his life.
X-rays can harm the tissue in the bones which is called bone marrow. X-ray can cause baldness that is the loss of hair on the head. X-rays also cause cancer development, thyroid cancer and invisible spectrum. X-rays have biological radiation effects, which are observed when ionizing radiation strikes living tissue and destroys the molecules of cellular matter. Birth defects are also known as congenital disorders are abnormalities of structure or function that exists at birth. Pregnancy and childbirth imply the gestation period of the human reproductive cycle. Bone marrow is a soft and pulpy tissue that fills the bone cavities, which occur in two forms i.e. red and yellow. Hair loss is a baldness or alopecia that is partial or complete loss of hair affecting the scalp. Thyroid cancer also known as endocrine gland occurs in all vertebrate animals.

Not only the X Ray but any radio wave carrying more energy than 2W is risky for us if exposed for longer.
But the X-Rays that are used for medical purpose have a specific energy which don't kill cells instantly. However prolonged exposure may be fatal. Also they are exposed on us just for fraction of second. So they are not harmful.
But for new born babies or children having delicate cells they may be harmful. But if there is need to take X Ray for medical purpose, and if X Ray is taken by specialist they aren't harmful.

Background radiation is around 0.24 Rem per year. A standard medical x-ray is about 0.002 Rem.
