What was the date of the Chernobyl meltdown?
04.26.1986
100
True or False: Radiation is deadly even if it is absorbed in small doses.
False: Radiation is not deadly in small doses. This is how we are able to use cell phones, computers, etc.
100
What is the type of Uranium that is used in weapons and nuclear power plants?
Uranium-235 (U-235)
100
What is the most common form of enrichment for uranium?
Gaseous Diffusion
100
How many people were evacuated from the city of Pripyat?
About 50,000 people.
200
What was the man made error that added to the mayhem that caused the meltdown?
An operator at the plant failed to reprogram a computer to maintain a steady energy level.
200
How much radiation would kill you after an extreme exposure to it?
30,000 rads are a rough amount.
200
True or False: Uranium-235 (U-235) is the final product of uranium that is mined straight from the ground.
False: The first product of Uranium is the Uranium ore.
200
Name the other two types of enrichment that could be used.
Gas Centrifuge, Laser separation
200
What is the NRC and what year was it created?
Nuclear Regulatory Commission - 1974
300
What was the test that was being performed at the reactor at Chernobyl for?
It was to see if the reactor at Chernobyl could continue to function until the diesel generators at the plant could kick in.
300
What is the gland in your body that absorbs internal radiation first?
Thyroid Gland.
300
How many "isotopes" or types of uranium are there in uranium ore?
Three: Uranium-238, Uranium-235, and Uranium-234
300
What is the name of the gas that is used to lift off the Uranium-235 molecules from the ore?
Uranium Hexafluoride (UF6)
300
True or False: The radiation of the reactor from Chernobyl was traced in small doses all over the world.
True: There was no way to stop the radiation from spreading after it was already in the atmosphere.
400
True or False: There were over one hundred people at Chernobyl that died immediately due to the explosion of reactor #4.
False: There were two operators at the plant that died as an immediate result of the explosion.
400
What is the name of the machine that is used to start a nuclear chain reaction?
Cyclotron
400
What is the other possible nuclear fuel that could be used in both power plants and weapons?
Plutonium
400
What is the currently operating program that commercially sells enriched uranium in the USA?
NRC
400
Why is it that people are still capable of visiting the Chernobyl Plant today?
While there is radiation around the plant, you can visit but not stay because it is not harmful for a short period of time.
500
What was the exact time of the explosion of reactor #4 at Chernobyl.
1:24 AM
500
What are the three different categories for the measurement of radiation? (Choose whether you are answering in SI or Customary Measurement)
Emitted Radiation: SI – Becquerel (Bq) Customary – Curie (Ci) Absorbed Radiation or Dose: SI – Gray (Gy) Customary – Rad Biological Risk of Exposure: SI – Seivert (Si) Customary – (Rem)
500
What are the exact amounts of the different types of uranium "isotope" or types that make up the Uranium ore.
Uranium-238 = %99.30 Uranium-235 = %0.70 Uranium-234 = %0.01
500
True or False: The Uranium Hexafluoride (UF6) gas goes through an infinite cycle with the uranium ore and is never swapped out for new gas.
False: After there is enough Uranium collected in the filter of the circuit, the gas is sent through a pipe where the gas is condensed and then solidified.
500
What was the name of the firefighter chief that was from Pripyat that helped fight the fires at Chernobyl?
Leonid Telyatnikov
