On April 26, 1986, in what was the soviet union at the time a reacer exploded in the CHernobyl nuclear power plant, releasing large amounts of radiation. The fire that resulted from it sent waves of radioactively contaminated fallout into the atmosphere and across the surrounding geographical areas. The blast contaminated large areas in Ukraine, Belarus, and Russia and many people from the places directly surrounding Chernobyl were forced to evacuate. While it is certain that many people died as a direct result of this blast, the soviet-era cover-ups forbade doctors to cite Chernobyl as a cause of death for most cases.

Specifics about Radiation Therapy:Certain tests, such as ultrasounds and magnetic resonance imaging (MRI) scans, do not expose the fetus to radiation. However, the contrast material sometimes used in MRI has been linked with fetal abnormalities in lab animals. For this reason, contrast-enhanced MRI is not recommended during pregnancy.Chest x-rays involve a small amount of radiation. They are generally considered safe when the abdomen is shielded. Other tests, such as bone scans or computed tomography (CT) scans of the chest, abdomen, or pelvis, are more likely to expose the fetus to radiation. In rare cases when these scans are needed, doctors can adjust the way the test is done to limit the radiation exposure of the fetus as much as possible.The most common procedure practiced with breast cancer is a lum]]> Mon, 01 Oct 2007 15:02:11 +0000 mod http://radiationteratogen.pbwiki.com/FrontPage email.hidden@example.com (Amanda) Amanda edited FrontPage 2.)

What are possible sources of ionizing radiation?
Humans are exposed to natural sources of ionizing radiation in day to day life. These come from cosmic rays, soil, and air. However, exposure to this type of radiation is not sufficient to cause teratogenic effects, and one must be exposed to intense levels of other types of radiation in order to see the effects on the fetus.
