Answer:
Effective half-time of the tracer is 3.6 days
Explanation:
The formula for calculating the decay due to excretion for the first process is ;
here ;
= initial number of tracers
Then to the second process ; we have :
The total decay is as a result of the overall process occurring ; we have :
------ (1)
here ;
Putting the values in (1);we have :
As we also know that:
![\frac{1}{t_{1/2}} = \frac{[t_{1/2}]_{radiation}+[t_{1/2}]_{excretion}}{[t_{1/2}]_{radiation}*[t_{1/2}]_{excretion}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bt_%7B1%2F2%7D%7D%20%3D%20%5Cfrac%7B%5Bt_%7B1%2F2%7D%5D_%7Bradiation%7D%2B%5Bt_%7B1%2F2%7D%5D_%7Bexcretion%7D%7D%7B%5Bt_%7B1%2F2%7D%5D_%7Bradiation%7D%2A%5Bt_%7B1%2F2%7D%5D_%7Bexcretion%7D%7D)
![\frac{1}{t_{1/2}}_{effective}} = \frac{[t_{1/2}]_{radiation}+[t_{1/2}]_{excretion}}{[t_{1/2}]_{radiation}*[t_{1/2}]_{excretion}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bt_%7B1%2F2%7D%7D_%7Beffective%7D%7D%20%3D%20%5Cfrac%7B%5Bt_%7B1%2F2%7D%5D_%7Bradiation%7D%2B%5Bt_%7B1%2F2%7D%5D_%7Bexcretion%7D%7D%7B%5Bt_%7B1%2F2%7D%5D_%7Bradiation%7D%2A%5Bt_%7B1%2F2%7D%5D_%7Bexcretion%7D%7D)
= 3.6 days
Answer:
