AbsorbedDoseMeasurerangeSubclassSubtractionFnA FunctionQuantity is a Function that maps from one or more instances of ConstantQuantity to another instance of ConstantQuantity. For example, the velocity of a particle would be represented by a FunctionQuantity mapping values of time (which are ConstantQuantities) to values of distance (also ConstantQuantities). Note that all instances of FunctionQuantity are Functions with a fixed arity. Note too that all elements of the range of a FunctionQuantity have the same physical dimension as the FunctionQuantity itself

GrayrangeSubclassMeasureFnSI 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)
