Which among the following statements regarding Sb-122 and Xe-136 is TRUE?
A: Sb-122 is more stable than Xe-136
because of its atomic number
B: Xe-136 and Sb-122 are radioactive
C: Xe-136 is more stable than Sb-122
because of the amount of its neutrons
D: Sb-122 and Xe-136 are both stable
C.
What can detect the neutrons produced by U-235 undergoing nuclear fission?
A Geiger Counter containing Argon
and Boron trifluoride
What is the phosphor of a scintillation counter intended for the detection of gamma radiation?
NaI Crystals containing Thallium
(II) Iodide

A: In the Water surrounding the core of a Nuclear Reactor
B: In the Mushroom Cloud produced after a Hydrogen Bomb Explosion
C: In a particle accelerator after the bombardment of two nuclides
D: In the Sun’s Corona during a Solar Eclipse
A.
Across the three most notorious accidents regarding nuclear power plants: Three Mile Island, Chernobyl, and Fukushima, what is the most common cause for their failure that led to several environmental problems?
Loss of proper cooling and/or
moderator
The Bataan Nuclear Power Plant is planned to be retrofitted in hopes of using it for the first time. One point of concern is the material that would be used in the outer portions of the room housing the fuel rods. If the radiation coming from the fuel rods
would be a strong beta emission, what material should be utilized?
8.0 mm of Lucite
For a criminal case, two men are
interrogated in regards to an
attempted poisoning of a police
officer. During the investigation, it
was found out that both men had traces of Polonium-210 on their hands while a third accomplice of theirs had Po-210 on his clothes. Through analysis of the police officers stomach content, it was confirmed that he had ingested Po-210. Which among them is/are bound to die if not properly treated?
A: The police officer only
B: The two men and the third accomplice
C: The police officer and the two men
D: All four of them
A. The police officer only
Explanation: Po-210 undergoes alpha decay (Alpha particles have the lowest penetration but the highest biological destruction, thus deadly when ingested only)
