Some previous year solved questions are given below:
The half life of Th232 is 1.4 × 1010 years and that of its daughter element Ra238 is 7 years. What amount (most nearly) weight of Ra238 will be in equilibrium with 1gm of Th232 ?
(A) 5 × 10–10 gm
(B) 5.0 × 10–8 gm
(C) 1.95 × 10–9 gm
(D) 2 × 10–10 gm
Hence, the correct option is (A).
During nuclear explosion one of the products is 90Sr with half-life of 28.1 yr. If 1 µg of 90Sr
was absorbed in the bones of a newly born body instead of calcium, how much of it will
remain after 60 yr, if it is not lost metabolically?
(A) 0.184 µg
(B) 0.025 µg
(C) 0.262 µg
(D) 0.228 µg
Hence, the correct option is (D).
Hence, the correct option is (d).
Hence, the correct option is (a).
