Side 46 - Permissible dose may then be defined as the dose of ionizing radiation that, in the light of present knowledge, is not expected to cause appreciable bodily Injury to a person at any time during his lifetime.
Side 1069 - The genetic dose to a population is the dose which, if it were received by each person from conception to the mean age of childbearing, would result in the same genetic burden to the whole population as do the actual doses received by the individuals.
Side 192 - Any severe somatic injuries (eg leukemia) that might result from exposure of individuals to the permissible dose would be limited to an exceedingly small fraction of the exposed group; effects such as shortening of life span, which might be expected to occur more frequently, would be very slight and would likely be hidden by normal biological variations. The permissible doses can therefore be expected to produce effects that could be detectable only by statistical methods applied to large groups.
Side 1066 - Accidental high exposure. An accidental high exposure that occurs only once in a lifetime and contributes no more than 25 rems shall be added to the occupational dose accumulated up to the time of the accident.
Side 868 - USCA §89(a)( 1990) ('The Coast Guard may make inquiries, examinations, inspections, searches, seizures, and arrests upon the high seas and waters over which the United States has jurisdiction, Tor the prevention, detection, and suppression of violations of laws of the United States.
Side 227 - the roentgen shall be the quantity of x or gamma radiation such that the associated corpuscular emission per 0.001293 gram of air produces in air ions carrying 1 esu of quantity of electricity of either sign.
Side 479 - Accumulated dose. — The maximum permissible accumulated dose, in rems, at any age, is equal to 5 times the number of years beyond age 18, provided no annual increment exceeds 15 rems. Thus the accumulated MPD=5 (N— 18) rems where N is the age and greater than 18. This applies to all critical organs except the skin, for which the value is double.
Side 33 - Threshold limits should be used as guides in the control of health hazards and should not be regarded as fine lines between safe and dangerous concentrations.
Side 479 - Controlled area. A defined area in which the occupational exposure of personnel to radiation or to radioactive material is under the supervision of an individual in charge of radiation protection. (This implies that a controlled area is one that requires control of access, occupancy, and working conditions for radiation protection purposes.) Workload.
