Here is the equation for the alpha decay of radon-219 into polonium. Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron.

Radon is a naturally occurring radioactive gas produced from the decay of uranium in minerals and rocks. It can accumulate in workplaces — for example, in offices, underground locations and industrial ...

Radon is a colorless, odorless gas, radioactive gas that comes from the natural decay of uranium and radium found in nearly ...

The Environmental Protection Agency defined radon levels at or above 4 pCi/L (the number of radioactive decay events from radon in one liter of air per second) as dangerous, but approximately 34% ...

Radon is a colorless, odorless, radioactive noble gas. The natural decay of uranium and radium in soil and rock creates the gas. Radon can leak into buildings through cracks or gaps in basement ...
