Baby Tooth Survey

The Baby Tooth Survey was initiated by the Greater St. Louis Citizens Committee for Nuclear Information in conjunction with Saint Louis University and the Washington University School of Dental Medicine as a means of determining the effects of nuclear fallout in the human anatomy by examining the levels of radioactive material absorbed into the deciduous teeth of children. Founded by the husband and wife team of physicians Eric and Louise Reiss, along with other scientists such as Barry Commoner and Ursula Franklin, the research focused on detecting the presence of strontium-90, a cancer-c ...

Biodosimetry

Biodosimetry is a measurement of biological response as a surrogate for radiation dose. The International Commission on Radiation Units and Measurements and International Atomic Energy Agency have issued guidance on performing biodosimetry and interpreting data.

Biological effects of radiation on the epigenome

Ionizing radiation can cause biological effects which are passed on to offspring through the epigenome. The effects of radiation on cells has been found to be dependent on the dosage of the radiation, the location of the cell in regards to tissue, and whether the cell is a somatic or germ line cell. Generally, ionizing radiation appears to reduce methylation of DNA in cells. Ionizing radiation has been known to cause damage to cellular components such as proteins, lipids, and nucleic acids. It has also been known to cause DNA double-strand breaks. Accumulation of DNA double strand breaks c ...

Blister

A blister is a small pocket of body fluid within the upper layers of the skin, typically caused by forceful rubbing, burning, freezing, chemical exposure or infection. Most blisters are filled with a clear fluid, either serum or plasma. However, blisters can be filled with blood or with pus. The word "blister" entered English in the 14th century. It came from the Middle Dutch "bluyster" and was a modification of the Old French "blostre", which meant a leprous nodule - a rise in the skin due to leprosy. In dermatology today, the words vesicle and bulla refer to blisters of smaller or greate ...

Carcinogen

A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis, the formation of cancer. This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is ...

Carcinogenesis

Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells. The process is characterized by changes at the cellular, genetic, and epigenetic levels and abnormal cell division. Cell division is a physiological process that occurs in almost all tissues and under a variety of circumstances. Normally the balance between proliferation and programmed cell death, in the form of apoptosis, is maintained to ensure the integrity of tissues and organs. According to the prevailing accepted theory of carcinogenesis, the ...

Prehydrated electrons

Prehydrated electrons are free electrons that occur in water under irradiation. Usually they form complexes with water molecules and become hydrated electrons. They can also react with the bases of the nucleotides dGMP and dTMP in aqueous solution. This suggests they may also react with the bases of the DNA double helix, ultimately breaking molecular bonds and causing DNA damage. This mechanism is hypothesized to be a cause of radiation damage to DNA.
