What does a whole-body dose of 5000 mrem correspond to in mSV?

25 mSV
50 mSV
75 mSV
100 mSV

The correct answer is: 50 mSV

To convert millirem (mrem) to millisievert (mSv), it is important to use the appropriate conversion factor. The conversion factor between these two units is 1 mSv = 100 mrem. Therefore, to convert a whole-body dose of 5000 mrem to mSv, you would divide the number of millirem by 100. 5000 mrem ÷ 100 = 50 mSv Hence, a whole-body dose of 5000 mrem corresponds to 50 mSv, making this option the correct one. Understanding this conversion is crucial for those in radiologic technology and radiation safety, as it allows them to interpret radiation dose levels accurately and assess potential biological effects of radiation exposure on the body.
