The Millisievert (mSv) in Radiation

What is Millisievert (mSv)

The millisievert (mSv) is a unit of measurement used to quantify the biological effect of ionizing radiation on human health. It indicates the dose of radiation received and is a derived unit in the International System of Units (SI). The millisievert is equal to one-thousandth of a sievert (Sv), which is the SI unit for measuring the biological impact of radiation.

Radiation exposure can come from various sources, including medical procedures (like X-rays), natural background radiation (from cosmic rays or radon gas), and occupational exposure (for instance, in certain jobs in healthcare or nuclear energy). Understanding the dose in millisieverts helps to assess potential health risks and guide safety regulations.

The biological effects of radiation are not solely based on the energy deposited in tissues, which is measured in gray (Gy) but also depend on factors like the type of radiation and how it interacts with biological systems. This is why the sievert and millisievert are important—they account for the effectiveness of different types of radiation in causing damage.
