In this question, we are trying to calculate a percent.
00:06
And percent means what part of the whole? so to calculate this, we are interested in the percent that a person receives from nuclear medicine.
00:20
So in the numerator, we're going to put the dose from nuclear medicine.
00:30
That is the part that we're interested in.
00:36
And in the denominator we need to put the hole.
00:39
Or the hole here is we want the total annual radiation from artificial sources.
00:44

00:55

So this is going to give us a decimal number to convert it to a percent.
00:58
Once we calculate it, we'll multiply by 100 and add the percent.
01:03
Okay, so let's calculate this percent of annual radiation...
