Which is a difference between the focus of a nuclear engineer and the job of a nuclear chemist?
nuclear engineers are concerned with the design, construction, and operation of nuclear reactors; nuclear chemists study nuclear reactions, radioactive elements, and nuclear power.
nuclear chemists are concerned with the design, construction, and operation of nuclear reactors; nuclear engineers study nuclear reactions, radioactive elements, and nuclear power.
nuclear engineers are concerned with the production and use of radioactive sources; nuclear chemists study the absorption of radiation.
nuclear chemists are concerned with the production and use of radioactive sources; nuclear engineers study the absorption of radiation.

The correct difference is :

Nuclear engineers are concerned with the design, construction, and operation of nuclear reactors; nuclear chemists study nuclear reactions, radioactive elements, and nuclear power.

Explanation:

Nuclear engineer : There main job is to develop processes ,instruments and systems so as to use the nuclear energy to its maximum extent for various uses in economical ,industrial and medical sectors.

Nuclear chemist: There main job is to research and study radio active substance and nuclear reactions or processes related to these substance. They further implement their knowledge regarding these substance in order to solve real world problems
