Conversion from Gray to Sievert
Convert the absorbed dose (Gray) of radiation absorbed by the human body to the effective dose (Sievert) that affects the human body.
A gray (Gy) is the amount of energy absorbed by an object per unit mass (Gy = J/kg).
A sievert (Sv) is the effective dose of radiation that affects the human body (Sv)
Effective dose = Absorbed dose × Radiation weighting factor × Tissue weighting factor
A sievert (Sv) is the effective dose of radiation that affects the human body (Sv)
Effective dose = Absorbed dose × Radiation weighting factor × Tissue weighting factor
Calculations are based on coefficient data from the ICRP 2007 Recommendations.
Effective dose is estimated based on the average equivalent dose received by the tissues of a standard person.
Tissues with active cell division are generally more susceptible to the effects of radiation.
