How does the water get into the ground?
When rain falls to the ground, the water does not stop moving. It seeps into the ground.Water seeps into the ground, such as glass of water poured onto a pile of sand.
Explain Why ventilation is very important if there is risk of exposure to radon gas in your home or school?
Radon gas is a colorless, odorless, radioactive gas. If you inhale it it can cause lung cancer. It seeps out of the ground and can enter a dwelling. If this is happening the dwelling needs to be well ventilated to reduce the chance of inhaling enough to cause the cancer.
What is radon-222?
Radon-222 is one of the isotopes or the inert gas radon. It is the longest-lived occurring one, and it appears as a daughter of the radioactive decay of radium (226Ra). It is radioactive (as are all of radon's isotopes), and, as such presents a hazard to people. The 222Ra isotope undergoes alpha decay to become polonium-218 (218Po). It is uranium that is the culprit as regards the source of radon. Uranium is the source of radium, and from radium we see radon. Uranium is present in the ground in a number of types of rock, so radon could appear in soil samples, in ground water, or in the lower internal spaces in buildings (because is seeps in). Radon is considered to be the second leading cause of lung cancer, and is an underrated threat. Testing for radon in structures is a bit tedious, but it can be done. If there is a question about a radon threat to your home, testing is not outrageously expensive. Call your county health office and get a "threat assessment" for your area. Just remember that though your neighbor's house might be well under recommended limits, yours may not, as there are variables to consider. Use the link below for more information.
What is percolation in filtration?
when water seeps into the ground and forms aquifers
Radon gas seeps out of rocks underground why is it important to stop radon collecting in houses?
Radon gas is a radioactive gas.In high risk areas,houses may need extra underfoor ventilation to stop the gas collecting or,ideally,a sealed floor to stop it entering in the first place. Radon is a decay product of uranium, which is relatively common in the Earth's crust, but generally concentrated in ore-bearing rocks scattered around the world. Radon seeps out of these ores into the atmosphere or into ground water, and in these localities it can accumulate within dwellings and expose humans to high concentrations.Radiation exposure from radon is indirect. Radon has a short half-life (4 days) and decays into other solid particulate. These radioactive particles are inhaled and remain lodged in the lungs, causing continued exposure. People in affected localities can receive up to 10 mSv per year background radiation.
This radioactive gas sometimes seeps into and accumulates in houses?
Radon.
What ratioactive gas seeps intoo houses?
Radon
Where is background radiation highest in the UK?
Background radiation is highest in Cornwall and Devon, where there is a high source of Radon that seeps up from the ground as a gas,
What happens to rain that seeps into the ground high above the water table?
it evaporates
What happens to the most of the precipitation that falls to Earth's surface?
Seeps into the ground and becomes groundwater.
What is the water from rain snow and lake that seeps into the ground called?
The water that seeps into the ground after it precipitates is called ground water.
How does rainwater get into the ground?
It seeps in. Infiltration

Where does ground water come from?
Runoff or precipatation. Water seeps into the ground and forms ground water.
