	One Sievert is a large amount of radiation dosage, so typically it is used with a [[prefixes\|prefix]] of micro (µSv) or milli (mSv). For example, a common comparison of dosage is the banana equivalent dose which is the amount of absorbed radiation from eating one banana, equal to 0.1 µSv (bananas are ''naturally'' slightly radioactive due to their content of the unstable isotope Potassium-40). The radiation from eating bananas is ''very'' small, one would have to eat millions of bananas at once to get any appreciable radiation exposure.

For example, a common comparison of dosage is the banana equivalent dose which is the amount of absorbed radiation from eating one banana, equal to 0.1 µSv (bananas are ''naturally'' slightly radioactive due to their content of the unstable isotope Potassium-40).

To get a feel of how much radiation dosage that humans receive from various sources, take a look at this [https://xkcd.com/radiation/ visual by XKCD].
