Background Radiation
What is Back Ground Radiation?
Background Radiation is all around us.
We can do little to avoid it.Most background radiation comes from natural sources.
These Natural Sources Are
Cosmic RaysWhich is radiation that gets to
the earth from outer space.
AnimalsAnimals to produce natural
levels of Radiation
Rocks Some rocks give away
radioactive radon gas.
Soil and Plants The radioactive materials from
rocks absorbed by soil and therefore on to plants
While most artificial radiation comes from medical examinations such as X-ray photographs.
Artificial Radiation
How Do Rocks Contain Radioactivity
Some rocks contain radioactive substances that produce a radioactive gas called radon.
The pie chart shows the % of the different sources of background radiation that the public are exposed to.
What Is Radon?
Radon is a natural radioactive gas.
It comes from an extremely small amount of uranium that
is naturally found in all rocks + soil
What is Radon Detector?
A radon detector is a machine used to detect the presence of
radon gas.
Facts about Background Radiation
Is Radon Present in AllParts of Italy?
Yes Radon is present in all parts of Italy, but the gas disperses outside so the
levels of radon is normally very low.
2. Is Radon bad in our Lungs
The air we breathe also contains small amounts of
isotopes which are one of two atoms having the same
atomic number but a different mass number.
This produces radioactivity in our lungs
3. Is career conected to background Radiation?
There is lots of career connected to B.R. for example;
there is lots of physics and science for example
They are…
Building Materials and Background Radiation
