Crank
This for health and hazard purposes. The conventional thermometers contain mercury which is very dangerous to health. It is toxic which could cause poisoning, respiratory damage and kidney problems. Because of this, it is already illegal to use them for safety purposes. Temperature probes are much safer because they only use thermocouples.

What is a problem commonly associated with nuclear power facilities?
gregori [183]
(1) False, lots of energy is actually produced from nuclear fuel, if we didn't get much then we probably wouldn't use it
(2) False, its burning coal that contributes to acid rain, since it contains sulfur
(3) False again, we can control the reaction with aptly named control rods, which are typically made of boron, to absorb some of the neutrons flying around in the chain reaction
(4) True, radioactive waste is very difficult to dispose of, and is also very dangerous. Sources of radiation can remain so for millions of years
