Question

In a diagnostic test for leukemia, a person receives 4.1 mL of a solution containing selenium-75. If the activity of the selenium-75 is 45 μCi/mL , what dose, in microcuries, does the patient receive?

Answer 1

To solve this problem, we can simply calculate for the dose by multiplying the volume of solution containing Selenium 75 and the activity of the Selenium 75. That is:

dose = 4.1 mL * (45 μCi/mL)

dose = 184.5 μCi

Answer 2

Answer: Patient received $184.5\mu Ci$ of dose.

Explanation:

Volume of solution received by the patient = 4.1 mL

Activity of selenium-75 = $45\mu Ci/mL$

In one mL of solution there are $45 \mu Ci$ of selenium -75 dose,

In 4.1 ml  solution will contain=$45\mu Ci/mL\times 4.1 ml=184.5\mu Ci$

The patient received the dose of $184.5\mu Ci$ of selenium-75 in 4.1 mL solution.
