Science fair presentation!
By Nathanel Frenkel
What is my science fair presentation about? What is my question?
How do you measure radioactivity? How does it harm people?
I will be looking at several factors proving how radiation harms people... i will also learn how you can mesure radiation! However, only ionizing radiation, radiation strong enough to charge the atoms of the object it is in contact with!
How do you measure radioactivity ?
Where is the most radioactive place on earth?
How much is a normal amount?
People around Fukushima will get an excess 10,000 sieverts in their lifetime.
One CT Scan gives out 7,000 sieverts.
US radiation workers get around 50,000 sieverts per year.
Astronauts get 160,000 sieverts in a year on the International Space Station.
However, can you guess who gets the most dosage of sieverts per year?
Smokers, a smoker gets over 200,000 sieverts (or 200,000,000,000 microsieverts) per year because of the radioactive polonium and led in cigars and cigarettes.
