Less than 100 Bq/m 3 which is equal to about 2.7 pCi/L. World Health Organization recommends that radon levels be reduced to In Europe and Canada they use Becquerel's per cubic meterįour pCi/L is about equal to 150 Bq/m 3. Recommends that the level of radon in a home be reduced below 4.0 pCi/L. Trillionth of a curie of activity in a liter of air. Curie comes from Madame Curie, the renown scientist whoĭetermined the decay rate of radium in the 1920's. Measured in units of Curies which is equal to the decay rate of a gram That can get lodged in our lungs and damage the lung cells. Into our homes and decay into a series of short lived charged particles Radon's half life isĪbout 4 days, which is just enough time to float through the soil, get (non-reactive) which means radon can freely move through the soil. The next element after Radium 226 is RADON. The following is the decay series from Uranium 238 to Radium 226. The next element, Thorium 234 has only 24 Half of the uranium 238 is goneīecause the earth is also about 4.5 billion years old, but there's still Uranium 238 has a 4.5 billion year half life. Takes before half of the element has decayed or changed is know as theĮlements half life. The releases of energy causes varying amounts of damage to whatever surrounds it. Particle and changes into a different element. Means that the element or atom gives off energy which may a solid Pennsylvania in particular has a lot of it. The world you can find some radioactive Uranium 238 in the soil. Radon originates from Uranium 238, a radioactive element.
