IPC Unit 8 Quizs

There are several safety mechanisms in nuclear fission reactors, including electromagnets that turn off when there is a power outage. Why are so many safety features needed?

• it is a natural chain reaction but the safety features are just for regulation purposes

• it is a chain reaction that can get out of control

• it requires extremely high temperatures

• it is hypothetical and not yet realized

Which of the following is an advantage of using nuclear plants to supply energy, rather than fossil fuel power plants?

Why is nuclear fusion considered safer than nuclear fission?

• fusion takes energy to be sustained so you can stop the reaction by taking away energy

• fusion is a chain reaction that must be controlled or it will get out of control

• fission takes energy to be sustained so you can stop the reaction by taking away energy

• they are equally unsafe

Nuclear fission as an energy source has a serious drawback in that it produces radioactive by-products that must be disposed of safely. Which of the following is a way in which some of those by-products can be used productively?

• by converting them into cleaning products

• by producing adhesives

• using them in medical applications

• using them to warm large buildings

Which of the following best describes how nuclear reactions are used to generate electricity?

• nuclei produced in reactions generate electromagnetic waves

• heat from fission is used to produce steam, which turns a turbine

• splitting nuclei give up their electrons, when they flow through wires

• light from fission is captured by photocells, which produce electricity

To discover if a cancer has metastasized, an oncologist might request a PET scan be performed by a radiologist. The PET scanner detects gamma radiation emitting from a chemical injected into the patient.

• decomposition

• fission

• fusion

• synthesis
