Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Radium and radon are important contributors to environmental radioactivity. Radon occurs naturally in the environment as a result of decay of radioactive elements in the soil and it can accumulate in houses built on areas where such decay occurs. This radon is among major causes of cancer, estimated to contribute to about 2% of all cancer related deaths in Europe.Radium, like radon, is a radioactive element and it is found in small quantities in nature and may thus be hazardous to life if concentrated. Radium has its origins as a decay product of certain isotopes of uranium and thorium.  Radium may also be released to the environment as a result of human activity, for example, in inproperly discarded products painted with radioluminescent paint.
