Problem 5.48 with feedback - Clinical Application You may want to reference (Ln pages 172-174) Section 5.6 while completing this problem. Part A As part of her nuclear stress test, Simone starts to walk on the treadmill. When she reaches the maximum level, Paul injects a radioactive dye with 201 Tl with an activity of 71 MBq. The radiation emitted from areas of her heart is detected by a scanner and produces images of her heart muscle After Simone rests for 3 h, Paul injects more dye with 201 Tl and she is placed under the scanner again. A second set of images of her heart muscle at rest is taken Radiation from 201 T to Simone's kidneys can be 21 mGy. What is this amount of radiation in rad? Express the radiation to two significant figures and include the appropriate units 2.4 ra The radioactive it is filtered out of the body and eliminated after the medical testing is complete dye passes through the kidneys as Submit My Answers Give Up Incorrect; Try Again; 5 attempts remainingExplanation / Answer
Answer:
We know the relation as
10 mGy = 1 rad
we want to know 21 mGy = ? rad.
Hence we write relationship as,
If 10 mGy = 1 rad
Then, 21 mGy = say 'A' rad
On cross multiplication,
A x 10 = 1 x 21
A = 21 / 10
A = 2.1 rad
21 mGy equals 2.1 rad.
