Among the listed average annual radiation doses, which value is the lowest?

Explanation:
When you compare average annual radiation doses, you compare the numbers in the same unit. The smaller the number, the lower the exposure. Here the four values are 120, 70, 20, and 10, all in the same units, so 10 is the smallest. Therefore, that value represents the lowest average annual dose. If units weren’t the same, you’d need to convert to a common unit before comparing.
