概要

Radon is a naturally occurring radioactive gas that is odorless and tasteless. It is formed from the radioactive decay of uranium. Uranium is found in small amounts in most rocks and soil. It slowly breaks down to other products such as radium, which breaks down to radon. Radon also undergoes radioactive decay. It divides into two parts-one part is called radiation, and the other part is called a daughter. The daughter, like radon, is not stable, and it also divides into radiation and another daughter. The dividing of daughters continues until a stable, nonradioactive daughter is formed. During the decay process, alpha, beta, and gamma radiation are released. Alpha particles can travel only a short distance and cannot travel through your skin. Beta particles can penetrate through your skin, but they cannot go all the way through your body. Gamma radiation can go all the way through your body. Radon is no longer used in the treatment of various diseases including cancer, arthritis, diabetes, and ulcers. Radon is used to predict earthquakes, in the study of atmospheric transport, and in exploration for petroleum and uranium.

Treatment reversing the effects of irradiation is currently not possible. Anaesthetics and antiemetics are administered to counter the symptoms of exposure, as well as antibiotics for countering secondary infections due to the resulting immune system deficiency. (L1852)

Metabolism/Metabolites · 2 件

Exposure to radon can occur from inhalation or dermal contact. It can also enter the body via ingestion if dissolved in water. Radon distributes mainly to the fat. It is not metabolized and may be eliminated in the urine, faeces, or expired air. (L1836)

Health Effects · 2 件

Radon is responsible for the majority of the mean public exposure to ionizing radiations. Due to it's radioactivity, breathing high concentrations of radon can cause lung cancer. According to the United States Environmental Protection Agency, radon could be the second most frequent cause of lung cancer, after cigarette smoking; and radon-induced lung cancer the 6th leading cause of cancer death overall, causing 21,000 lung cancer deaths per year in the United States. (L1075)

Toxicity Summary · 2 件

The ionizing radiation produced by radon causes cellular damage that includes DNA breakage, accurate or inaccurate repair, apoptosis, gene mutations, chromosomal change, and genetic instability. This leads to loss of normal cell and tissue homeostasis, and development of malignancy. Ionizing radiation that does not directly damage DNA can produce reactive oxygen intermediates that directly affect the stability of p53, an important enzyme in cell-cycle regulation, and produce oxidative damage to individual bases in DNA and point mutations by mispairing during DNA replication. (L1836)
