Radon in a sentence

The radon equilibrium factor citation is the ratio between the activity of all short-period radon progenies (which are responsible for most of radon's biological effects), and the activity that would be at equilibrium with the radon parent.

As radon itself decays, it produces other radioactive elements called radon progeny (also known as radon daughters) or decay products.

In the 1970s and 1980s, scientific measurements of radon emissions near faults found that earthquakes often occurred with no radon signal, and radon was often detected with no earthquake to follow.

Radon is the second-leading cause of lung cancer in the country after smoking, and the health risks from radon are greater for smokers.

Some radon reduction systems have been shown to reduce radon by up to 99%.

Take Action on Radon is funded by Health Canada to raise awareness of radon's health impacts across the country.

The EPA says no level of radon is safe and advises that mitigation efforts be taken when radon concentration reaches 148 becquerels per cubic meter; the study considered concentrations as low as half of that.

The P.E.I. Lung Association has added 15 more short-term radon detectors to the radon detector library loan program in an attempt to combat a 31-week wait list.

This results in more radon exposure and increased opportunities for radon to be inhaled by children.

Because of their electrostatic charge, radon progenies adhere to surfaces or dust particles, whereas gaseous radon does not.

For this reason, it has been hypothesized that increases in radon concentration is due to the generation of new cracks underground, which would allow increased ground water circulation, flushing out radon.

Generally indoor radon can be mitigated by sub-slab depressurization and exhausting such radon-laden air to the outdoors, away from windows and other building openings.

Here is a typical deposition rate of 210 Pb as observed in Japan as a function of time, due to variations in radon concentration. citation All discussions of radon concentrations in the environment refer to 222 Rn.

Homes built on a crawl space may benefit from a radon collector installed under a "radon barrier" (a sheet of plastic that covers the crawl space).

If a closed volume is constantly supplied with radon, the concentration of short-lived isotopes will increase until an equilibrium is reached where the rate of decay of each decay product will equal that of the radon itself.

In the US and Europe there are several "radon spas ", where people sit for minutes or hours in a high-radon atmosphere in the belief that low doses of radiation will invigorate or energize them.

Radon also can be released from the ground in bursts and then form "radon clouds" capable of traveling tens of kilometers.

The usefulness of radon compounds is limited because of the radioactivity of radon.

Unlike the gaseous radon itself, radon daughters are solids and stick to surfaces, such as dust particles in the air.

When it's convenient to work with a dominating measure, the Radon-Nikodym theorem is used to define a density as the Radon-Nikodym derivative of the probability distribution of interest with respect to this dominating measure.
