A small amount of solution containing a radioactive nucleide A was administered into blood of a patient. The activity of the nucleide is `2 xx 10^(3)` dps. Its hafl life is 15 hours. After 5 hours a sample of the a sample of the blood drawn out from the patient. It's activity was 16 dpm per mL.
What is activity of the sample after another 5 hours time ? `(log 1.59 = 0.2)`

A

11.18 dpm per mL

B

1.118 dpm per mL

C

12.71 dpm per mL

D

1.271 dpm per mL

Text Solution

Verified by Experts

The correct Answer is:
C
Activity of sample after another 5 hours is y
`(0.693)/(15) = (2.303)/(5) log ""(16)/(y), y = 12.71 ` dpm mL

A small amount of solution containing a radioactive nucleide A was administered into blood of a patient. The activity of the nucleide is 2 xx 10^(3) dps. Its half life is 15 hours. After 5 hours a sample of the blood drawn out from the patient. It's activity was 16 dpm per mL. Radioactive nuclide A^(x) decays by beta^(-) emission (42%) beta^(+) emission (58%) in the patient body Then half value of beta^(-) decay path is
