About Sieverts
The sievert (Sv) is the SI coherent unit of equivalent and effective dose, equal to 1 J/kg of absorbed dose weighted by radiation type. Named after Rolf Sievert (Swedish radiophysicist, 1896-1966). Whole-body LD50 for acute exposure ~3-5 Sv; ICRP emergency responder limit 0.25 Sv; acute radiation syndrome threshold ~1 Sv. 1 Sv = 100 rem = 1 J/kg.
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.
