Conversion Formula

nSv = MSv × 1000000000000000

About Megasieverts

The megasievert (MSv) equals 10⁶ Sv. Entirely theoretical for biological contexts - severe radiation damage occurs well below 1 MSv. Appears in materials science modelling of extreme radiation environments, theoretical nuclear detonation effects at point of burst, and advanced reactor pressure vessel damage accumulation calculations. 1 MSv = 10⁶ Sv = 10⁸ rem.

About Nanosieverts

The nanosievert (nSv) equals 10⁻⁹ Sv. Ambient environmental gamma dose rates at sea level are ~30-50 nSv/h; portable radiation survey meters and environmental monitoring networks report ambient dose equivalent rates in nSv/h; airborne gamma spectrometry surveys record deposition rates in nSv/h. 1 nSv = 10⁻⁹ Sv = 10⁻³ µSv.
