Gray | domainSubclass | SystemeInternationalUnit | SI AbsorbedDoseMeasure. Symbol: Gy. It measures the dose of radiation absorbed in living tissue. It is equal approximately to the absorbed dose delivered when the energy per unit mass imparted to matter by ionizing radiation is 1 Joule per Kilogram. Gray = J/kg = m^2*s^(-2) | Physical | rangeSubclass | MeasureFn | ConstantQuantity, FunctionQuantity | (=> (and (instance ?REL RelationExtendedToQuantities) (instance ?REL BinaryRelation) (instance ?NUMBER1 RealNumber) (instance ?NUMBER2 RealNumber) (holds ?REL ?NUMBER1 ?NUMBER2)) (forall (?UNIT) (=> (instance ?UNIT UnitOfMeasure) (holds ?REL (MeasureFn ?NUMBER1 ?UNIT) (MeasureFn ?NUMBER2 ?UNIT)))))
