Question : Two elements which are used to absorb neutrons to control the chain reaction during nuclear fission are
Option 1: Boron and Cadmium
Option 2: Boron and Plutonium
Option 3: Cadmium and Uranium
Option 4: Uranium and Boron
Correct Answer: Boron and Cadmium
Solution : The correct answer is Boron and Cadmium.
Nuclear reactors make use of boron and cadmium as materials that absorb neutrons in control rods, which help to regulate the fission reaction rate. Boron-10 and cadmium-113 are particularly efficient at absorbing neutrons and assist in managing and controlling the chain reaction within the reactor core.
