The dose equivalent in soft tissue at an appropriate depth, d, below a specified point on the human body. The soft tissue is ICRU 4-element tissue. The unit of personal [[dose equivalent]] is joule per kilogram (Jkg<sup>-1</kgsup>), and its special name is [[Sievert]] (Sv). The specified point is usually given by the position where the individual dosimeter is worn. For the assessment of [[effective dose]] a depth of 10 mm is recommended, and for the assessment of [[equivalent dose]] to the skin and the lens of the eye, depths of 0.07 mm and 3 mm, respectively, are recommended.

=== from [[ICRP Publication 131139]], 2015 2018 === The operational quantity for individual monitoring is the personal dose equivalent H<sub>p</sub>(d) which is the dose equivalent in soft tissue at an appropriate depth d (in mm) below a specific point on the human body. The unit of personal dose equivalent is J kg<sup>-1</sup> and its special name is [[sievert]] (Sv). The specified point is usually given by the position where the individual’s dosimeter is worn. For monitoring effective dose the operational quantity H<sub>p</sub>(10) is used and for assessment of the dose to the skin hands and feet the personal dose equivalent H<sub>p</sub>(0.07) is used. A depth d = 3 mm is adequate for monitoring the dose to the lens of the eye. In practice however in many countries calibration of dosimeters in terms of H<sub>p</sub>(3) has not been implemented but H<sub>p</sub>(0.07) can be used for the same monitoring purpose for photon radiation which is the case in interventions guided by radiological imaging. === from [[ICRP Publication 103]], 2007 === An operational quantity: the dose equivalent in soft tissue (commonly interpreted as the ‘ICRU sphere’) at an appropriate depth, d, below a specified point on the human body. The unit of personal dose equivalent is joule per kilogram (J kg<sup>-1</sup>) and its special name is [[Sievert]] (Sv). The specified point is usually given by the position where the individual’s dosimeter is worn.
