Radon Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas. It occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead; radon, itself, is a decay product of radium. Its most stable isotope, 222Rn, has a half-life of 3.8 days.

Radon Fact Sheet Radon is a naturally occurring radioactive gas and comes from the natural breakdown (radioactive decay) of uranium. It is usually found in igneous rock and soil, but in some cases, well water may also be a source of radon.

- Asthma and Reactive Airway Disease (RAD) (Wheezing) Asthma and Reactive Airway Disease (RAD) are conditions in which the airways (bronchi) in the lungs overreact to certain things. Understanding what the lungs look like and how they work will help you understand asthma or RAD episodes and how to control them.

- Radon is a radioactive, colorless, odorless, and tasteless gas. It is formed as natural deposits of uranium throughout the earth's crust decay. As radon decay products are inh…aled, they can alter the cells in the lungs. These alterations can increase the potential for getting lung cancer.

What is Radon? All homes have some level of radon - the only way to know how much is to test. Radon is a radioactive gas found naturally in the environment. It is produced by the decay of uranium found in soil, rock or water. Radon is invisible, odourless and tasteless and emits ionizing radiation. As a gas, radon can move freely through the soil enabling it to escape to the atmosphere or seep into buildings.

Bomb Shelter FAQâs Radiological Dispersion Device. Terrorist use of a Radiological Dispersion Device (RDD) — often called “dirty nuke” or “dirty bomb” — is considered far more likely than use of a nuclear explosive device. An RDD combines a conventional explosive device — such as a bomb — with radioactive material.

Its most stable isotope, 222Rn, has a half-life of 3.8 days.Radon is one of the densest substances that remains a gas under normal conditions.hree other radon isotopes have a half-life of over an hour: 211 Rn, 210 Rn and 224 Rn. The 220 Rn isotope is a natural decay product of the most stable thorium isotope (232 Th), and is commonly referred to as thoron. It has a half-life of 55.6 seconds and also emits alpha radiation.

- Live Search Images. Reactive airway disease is a general term often used interchangeably with asthma. Symptoms of wheezing, shortness of breath and cough are symptoms of reactive airway disease (RAD), but despite the similarity, those symptoms don't necessarily mean you have asthma. The two are different. RAD causes the airways to become inflamed, swollen and produce mucous, leading to sputum production.

- A: Radon is an odorless radioactive gas that results from the breakdown of uranium. Uranium is present in most of the soil and rock around the world. It is typically concentrated in areas with lots of granite, shale, phosphate and pitchblende.: Because radon is a gas, it can leak into your house through the basement or crawl space--via adjacent or exposed soil and rock--or through well water.

- Most ringworm infections of the skin, such as jock itch, can be treated at home with antifungal creams and powders you can buy without a prescription. But have your doctor look at any infection that does not go away, is severe, or comes back. Wash the rash with soap and water. Spread an antifungal cream over the rash.

Causes, Symptoms & Effects of Attachment Disorders Reactive attachment disorder (RAD) is a complex, severe, and relatively uncommon condition in which infants and young children do not establish lasting, healthy bonds with parents or caregivers. While this condition is rare, it is serious. In many cases a child with RAD has been the victim of abuse, neglect, or abandonment or is orphaned.

- Radon is a gas that occurs naturally from the breakdown—or the radioactive decay—of uranium. Rocks, soil, and in some cases groundwater can all contain uranium.Because radon comes from so many sources, people are easily exposed to it.adon is an odorless, colorless, radioactive gas. It is also the second leading cause of lung cancer in the United States.

- What is radon? Radon is a radioactive gas that causes cancer. Radon is found in rock, soil, water, some building materials, and natural gas. You can't see, taste, or smell it. How does radon exposure occur? Any home, school, office, or other building can have high levels of radon. Radon is found in new and old buildings.

Radon and Cancer Radon is a colorless, odorless, radioactive gas. It forms naturally from the decay (breaking down) of radioactive elements, such as uranium, which are found in different amounts in soil and rock throughout the world. Radon gas in the soil and rock can move into the air and into underground water and surface water.

Radium Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen on exposure to air, forming a black surface layer of radium nitride. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas. When radium decays, ionizing radiation is a

Reactive airway disease For other uses, see RAD. Reactive airway disease is a group of conditions that include reversible airway narrowing due to an external stimulation. These conditions generally result in wheezing. Conditions within this group include asthma, chronic obstructive pulmonary disease, and viral upper respiratory infections.

Radian A radian is a unit of angular measure. A turn in a full circle has an angle of 2π radians. A radian is a unit of measuring angles. It is shown by the symbol rad or, less often, c (for circular measure). The radian was once an SI unit, but was done away with in 1995. A milliradian is 1/1000 of a radian.
