About Radiation Conversion

Radiation unit conversions are used in medical imaging, nuclear physics, and radiation safety.

Frequently Asked Questions

What is a Sievert?

The Sievert (Sv) measures biological effect of ionizing radiation on human tissue.

Can you convert gray to sievert?

Not with a fixed factor. Gray measures absorbed energy, while sievert also weights for the type of radiation: the weighting factor is 1 for X-rays, gamma rays and beta particles but 20 for alpha particles. This converter therefore keeps absorbed dose (Gy, mGy, rad) and equivalent dose (Sv, mSv, rem) separate.
