Uses of uranium
•One way uranium is used is to help harden and strengthen steel
•Another way uranium is used for is in gyrocompasses,
compasses that find true north
•Uranium is also used as counterweights for planes’ control
surface
•Uranium is used for x-rays and nuclear weapons also
•Depleted uranium is used to protect tanks
Hazardous effects to the
environment, animals, and humans
•Contaminates river systems and ground water by the
radioactive uranium dissolving into it
•The radioactive dust moves which goes in water, in plants,
into animals and humans
•If it can go into us humans, we can get damage in our lungs,
kidneys, bones, and many other places. Eventually, this will
lead to diseases like cancer or leukemia
•The uranium can leave tailings which pollute the air or
water and then get into animals or humans
Interesting facts
Did you know…?
•… that the fist atomic bomb used in warfare was an
uranium bomb?!?!
•… that the world production of uranium is 35,000 tons
(35,0000,000 kg)?!?!
•… that only one ton of natural uranium can make more
than 40 million kilowatt-hours of electricity?!?! That’s equal
as to burning 16,000 tons of coal or as equal to burning
80,000 barrels of oil!!!!!!!
•… that uranium that is the size of a gallon milk jug weighs
over 150 lbs (about 60 kg)?!?!
More random facts
•Uranium has 92 protons and 146 neutrons in the nucleus
•Is ranked 48th for most abundant element in natural crustal rock
•Acids can dissolve uranium
•When uranium is exposed to air, the uranium becomes coated
with a layer of oxide
•Uranium compounds are highly toxic. So be careful.
