For neutron activation analysis of an element, the favourable characteristics of both the target and the product are from the following:(A) high neutron cross-section area of target(B) long half-life of the product(C) low neutron cross-section area of target(D) low half-life time of the product.The correct characteristics from the above are
(a)1 and 2
(b)2 and 3
(c)3 and 4
(d)1 and 4
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
A large neutron-capture cross-section of the target gives high activity; the product should have a convenient (not too long) half-life with measurable γ-emission.
