What unit is used to measure effective dose in radiation exposure?

Effective dose in radiation exposure is measured in Sieverts. The Sievert is a derived unit that quantifies the biological effects of radiation, taking into account the type of radiation and the sensitivity of the tissues being irradiated. This unit helps in assessing the potential risk associated with exposure to ionizing radiation, thereby providing important information for radiation protection and safety.

The effective dose is specifically designed to reflect how the absorbed dose of radiation affects the overall risk of cancer and genetic damage to tissues. It allows for comparison of different types of radiation and their potential harm.

Other units such as Gray, Rad, and Rads measure absorbed dose, which refers only to the amount of energy deposited in tissues, without taking into account the biological effects or varying sensitivities of different tissues exposed to radiation. The focus on the Sievert makes it crucial for evaluating risks associated with varying sources and types of radiation exposure in medical settings and occupational safety.
