Neutrons interact with matter in different ways. Four materials M1, M2, M3 and M

Question

Neutrons interact with matter in different ways. Four materials M1, M2, M3 and M4, , are supposed to be used for shielding against neutrons. Assuming that: Neutrons react with M1through (n,n’) reaction Neutrons react with M2through (n, p) reaction Neutrons react with M3through (n,gamma) reaction Neutrons react with M4through (n,alpha) reaction Circle the correct answer in the following statement: For an efficient protection against neutrons, materials should be used as follow: a) M1 followed by M4 b) M3 followed by M1 c) M1 followed by M3 d) M1 alone

Explanation / Answer

Option C would be correct.

Explanation: Since we have to minimize the number of neutrons at the end of consecutive reactions such to have a efficient protection against neutrons.

The absorption of neutron through shielding with the help of gamma rays could be done.Hence finally there would be no neutrons.as M1 followed by M3 is favourable.
