What is the metric unit of radiation measurement for occupational dose?

The metric unit of radiation measurement for occupational dose is the sievert (Sv). It quantifies the biological effect of ionizing radiation on human tissues, taking into account the type of radiation and its impact on health. For practical purposes, doses are often expressed in millisieverts (mSv), where 1 Sv equals 1,000 mSv. This unit helps ensure that occupational exposure to radiation remains within safety guidelines.
