Answer 1

In addition to the Sievert that is used for human radiation absorption, there are a few other similar units.

The Becquerel is the unit of radioactive emission, how much radiation is being thrown from the radioactive material.

The Grey is the unit of radiation absorbed per kilogram of material, this kilogram is not necessarily a human, but is general.

As others have said, the Sievert is then used to show the biological effects from a radiation source.

We have these different measurements because not all radiation is the same, and sometimes we need the information external to radiation effects on humans.
