Dose equivalent at a point in a radiation field that would be produced by the corresponding expanded field in the ICRU sphere at a depth, d, on a radius in a specified direction, Ω. The directional dose equivalent is one of the operational quantities defined for use in area monitoring against external exposures. The directional dose equivalent at a depth of 0.07 mm, H'(0.07, Ω) is used to monitor the equivalent dose to the skin; the directional dose equivalent at a depth of 3 mm, H'(3, Ω) is used to monitor the dose to the eye lens. The unit of directional dose equivalent is joule per kilogram (J kg-1) and its special name is sievert (Sv).

The dose equivalent at a point in a radiation field that would be produced by the corresponding expanded field in the ICRU sphere at a depth, d, on a radius in a specified direction, Ω. The SI unit of directional dose equivalent is joule per kilogram (J kg-1) and its special name is Sievert (Sv).
