The phrase dose equivalent is only used for which use Q for calculation, and the following are defined as such by the ICRU and ICRP: ambient dose equivalent; directional dose equivalent; personal dose equivalent; In the US there are further differently named dose quantities which are not part of the ICRP system of quantities. [16]
Personal Dose Equivalent is a radiation quantity specifically designed to be used for radiation measurements by personal dosimeters. [4] Dosimeters are known as "legal dosimeters" if they have been approved for use in recording personnel dose for regulatory purposes.
The operational quantity for personal dosimetry is the personal dose equivalent, which is defined by the International Commission on Radiological Protection as the dose equivalent in soft tissue at an appropriate depth, below a specified point on the human body. The specified point is usually given by the position where the individual’s ...

The internal radiation dose due to injection, ingestion or inhalation radioactive substances is known as committed dose.. The ICRP defines Committed effective dose, E(t) as the sum of the products of the committed organ or tissue equivalent doses and the appropriate tissue weighting factors W T, where t is the integration time in years following the intake.
Additional dosimeters can be worn to assess dose to extremities or in radiation fields that vary considerably depending on orientation of the body to the source. The dose measurement quantity, personal dose equivalent Hp(d), is defined by the International Commission on Radiological Protection (ICRP) as the dose equivalent in soft tissue at an ...
CDE is defined by the United States Nuclear Regulatory Commission in Title 10, Section 20.1003, of the Code of Federal Regulations (10 CFR 20.1003), such that "The Committed dose equivalent, CDE (H T,50) is the dose to some specific organ or tissue of reference (T) that will be received from an intake of radioactive material by an individual during the 50-year period following the intake".
The deterministic effects that can lead to acute radiation syndrome only occur in the case of high doses (> ~10 rad or > 0.1 Gy) and high dose rates (> ~10 rad/h or > 0.1 Gy/h). A model of deterministic risk would require different weighting factors (not yet established) than are used in the calculation of equivalent and effective dose.
