Memorandum from the British Committee on Radiation Units and Measurements. Advice following ICRP publication 60. 1993

In summary, it is recommended that: (i) The three operational quantities defined by ICRU, namely ambient dose equivalent, directional dose equivalent and personal dose equivalent, should be used for measurement in radiation protection. (ii) The values of these quantities should, for the present, be based on values of Q recommended in ICRP Publication 26 (ICRP, 1977). (iii) The values of organ weighting factors, wT, recommended in ICRP Publication 26 (ICRP, 1977) should, for the present, be retained. (iv) The operational quantities should not be modified to incorporate the values of Q recommended in ICRP Publication 60 (ICRP, 1991) until it has been demonstrated that they are satisfactory indicators of the limiting quantities defined in ICRP 60. (v) Any changeover to the new values of the operational quantities should take place on a defined date.

UI MeSH Term Description Entries
D011829 Radiation Dosage The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
