Sievert ⇔ Gray Radiation measurement
value conversion tool.

Equivalent dose(Sv) ＝ Absorbed dose(Gy) × Equivalency Weighting Factor

Equivalency Weighting Factor is decided with the kind of radiation.

Kind of radiation.
X-rays, γ-rays, Beta radiation, Muon Neutron less than 10KeV. Neutron more than 20,000KeV. Neutron 10 - 100KeV. Neutron 2,000 - 20,000KeV. Neutron 100 - 2,000KeV. Proton more than 2MeV. Fission fragment, Heavy nucleus, α-rays
