MRI Equipment
Liquid helium plays an important role in magnetic imaging equipment (MRI).
Nuclear Research
When the temperature of helium is close to absolute zero, it becomes a "liquid on" with special properties such as friction, lack of viscosity and high heat conductivity, which can be used to study nuclear processes.
Balloons and Blimps
Helium, which is lighter than air and safer than hydrogen (as it is not combustible), is used for filling balloons and blimps.
Scuba Diving Balloons
At a depth greater than 600 meters, a mixture of helium, oxygen and nitrogen is used.
