| genetically significant dose | <physics, radiobiology> The genetically significant dose is that which, if received by every member of the population, would be expected to produce the same genetic injury to the population as do the actual doses received by the individuals irradiated. Thus, the genetically significant dose is the dose equivalent to the gonads weighted for the age and sex distribution in those members of the irradiated population expected to have offspring. The genetically significant dose is expressed in sieverts (or rem). Acronym: GSD (06 Aug 1998) |

| mastectomy, modified radical | Total mastectomy with axillary node dissection, but with preservation of the pectoral muscles. (12 Dec 1998) |

| modified radical hysterectomy | An extended hysterectomy in which a portion of the upper vagina is removed; the ureters are exposed and pulled back laterally without dissection from the ureteral bed. Synonym: TeLinde operation. (05 Mar 2000) |
