Specified dose equivalent quantities for neutrons in the ICRU sphere and their applicability.
Radiat. Prot. Dosim. 12, 107-111 (1985)
New quantities have been specified by ICRU for use as operational or calibrational quantities in radiation protection dosimetry. These are the ambient dose equivalent, H*(10), and the directional dose equivalent, H'(0.07), for environmental, and H(p)(10) and H(s)(0.07) for individual dosimetry. The first two quantities are defined in the ICRU sphere and the fluence-to-dose equivalent conversion functions can be calculated. The latter two quantities are defined below a specified point on the surface of the trunk at depths of 10 and 0.07 mm. They have basically nothing to do with the ICRU sphere. Yet the calibration of individual dosemeters worn on the trunk should be performed in or on the 30 cm sphere, respectively. The corresponding calibration quantity, whenever not explicitly defined, is hence the dose equivalent below a specified point on the surface of the sphere. There is no mention of whether this calibration quantity is a directional one or whether it is defined only for AP radiation. Problems related to this question will be discussed, the fluence-to-dose equivalent conversion functions for the calibration quantity assesed, and its relationship with other well defined quantities in the sphere demonstrated.
