A) 5.94 litre
B) 2 litre
C) 317 litre
D) 1 litre
Correct Answer: A
Solution :
R0 = Initial activity = 1 micro curie = 3.7 ´ 104 d ps r = Activity in 1 cm3 of blood at t = 5 hrs \[=\frac{296}{60}dps=4.93\,dps\] R = Activity of whole blood at time t = 5 hr, Total volume should be \[V=\frac{R}{r}=\frac{{{R}_{0}}{{e}^{-\lambda t}}}{r}\] \[=\frac{3.7\times {{10}^{4}}\times 0.7927}{4.93}\]= 5.94 ´ 103 cm3 = 5.94 Litre.You need to login to perform this action.
