X-rays and radiation. About X-ray examinations, radiation dose and pregnancy. Is X-ray dangerous?
An X-ray study provides detailed images of the skeleton and soft tissues in the body and remains a very important tool to examine some of the body's internal structures. Also, although in recent years, a number of new imaging techniques. Where radiographs former alone could render dense structures like bone, is the development of contrast agents is now possible to look hollow and fluid-filled spaces in the body. Every year out millions and millions of X-ray studies. Some of those performed on women who later finds out that at the time of examination was pregnant.
What is X-ray radiation?
X-rays are closely related to both radio and light waves. The Rays sent from an X-ray tube in front of the patient through the patient to a photographic film, a TV camera or special detectors. The film will be stained black depending on the amount of radiation has been absorbed by the body tissue. In the film will the soft tissue so appear as dark shadows and bone tissue as white shadows. The radiation is electromagnetic waves as well as ordinary light but have a shorter wavelength so that it can not be perceived by the human eye. The short wavelength causes the X-radiation penetrating through the tissue, which is impermeable to ordinary light. When the image is produced, it is easy to distinguish bone from soft tissue, but harder to separate the soft parts from each other. Therefore one often uses a contrast agent so that the investigated member may appear clearer. Contrast agents can for example be injected into a vein of certain renal studies. Upon examination of the intestines can contrast medium drink.
What is the X-ray examinations for?
X-ray examinations may be performed on all parts of the body and is often used in combination with other studies to refute or confirm a diagnosis. The simplest form of X-ray investigation is a single recording, which is the most common form and special velegent to examine the spine, chest, skull and other parts of the skeleton. Is there a need to examine the cavity or fluid filled structures, it is possible to use the contrast agents - such as barium contrast to the study of the esophagus, stomach and intestines, and iodinated contrast media for the detection of e.g. the kidneys. In many cases, the previously used X-ray examinations, you choose today CT scan that produces series of sectional images. - Click to read the MRI and CT scan >>
Is X-ray radiation dangerous?
The risk of adverse effects after X-rays is very small. Modern X-ray apparatus is designed to capture images of very high quality by using very low radiation doses. At each survey efforts are being made to obtain a diagnosis with the least possible radiation dose. The most radiosensitive cells sitting in the ovaries and testes. Should we conduct a survey of areas closer than 10 cm in these bodies will be for safety's sake protect male patients with a blypung around the testes and female patients with a blystykke on the stomach. Radio chart and other personnel who work with X-rays for many years, leaving the space under investigation, or the use of lead apron so as not to expose themselves to unnecessary radiation. The reason is that a radiation dose that is safe for the person under investigation may be dangerous to personnel because radiographer making many X-rays a day, and thus gathered would be exposed to much radiation.
Pregnancy and X-ray?
X-ray studies of women of childbearing age performed with sharpened attention on whether the woman is pregnant. If you are pregnant you will either postpone the investigation or customize the survey, so the fetus gets so low a radiation dose as possible. Talk to your doctor or radiographer about your concerns and possibly put the risks of damage to the fetus, which may be associated with X-ray irradiation, in the right perspective. Dental X-rays and pregnancy: Dental X-rays is so low a radiation dose, there is no risk to fetus or the pregnant. Yet avoiding any major dental treatments during pregnancy. However, there is a need for X-ray protect the body against the X-rays through a lead shield. Either in the form of a large apron, a shoulder or collar. In addition, many hospitals today makes use of digital x-rays, whereby the already much small dose of radiation is minimized even further. Talk to your dentist about your concerns. - Click here to learn more about Dental visits during pregnancy >>
The amount of radiation dose depends on the type of X-ray examination to be carried out. The more complicated an investigation, the greater the radiation dose. Radiation dose is a measure of the amount of energy absorbed by the body in a study. The dosage is measured in Sievert (A), which is a large device. Therefore, given radiation dose by X-ray studies usually in millisievert (mSv). 1 Sv = 1,000 mSv. Radiation Doses from typical studies such as Arm: 0.1 mSv - Lungs: 0.3 mSv - Stomach: 1.5 mSv - low back: 5.0 mSv - Colon: 6.0 mSv - Renal Study: 7, 0 mSv - CT scan head: 2.0 mSv.
What other radiation exposure we humans?
A human is typically a radiation dose of approx. 5 mSv per year. The majority comes from natural sources such as: From your own body, radioactive substances in the body: 0.2 mSv - From outer space and the sun: 0.3 mSv - From the ground: 0.5 mSv - Radon, radioactivity in soil and building materials: 3, 0 mSv - Studies: 0.6 mSv.
