Page 6 - An accidental or emergency dose of 25 rems to the whole body or a major portion thereof, occurring only once in the lifetime of the person, need not be included in the determination of the radiation exposure status of that person (see p.
Page 5 - X 5 rems, where N is the age in years and is greater than 18. COMMENT: This applies to radiation of sufficient penetrating power to affect a significant fraction of the critical tissue (This will be enlarged upon in the revision of H59.) B. External exposure to other organs.
Page iii - Advisory Committee on X-ray and Radium Protection was organized to develop recommendations on the protection problem within the United States and to formulate United States points of view for presentation to the International Commission on Radiological Protection. The organization of the US Advisory Committee included experts from both the medical and physical science fields. As a result of the extensive developments immediately preceding and during World War II that added substantially to the importance...
Page 5 - The maximum permissible average concentrations of radionuclides in air and water are determined from biological data whenever such data are available, or are calculated on the ba.sis of an averaged annual ,dose of 15 rems for most individual organs of the body,4 30 rems when the critical organ is the thyroid or skin, and 5 rems when the gonads or the whole body is the critical organ.
Page 6 - This will normally entail control of the average concentrations in air or water at the point of intake, or rate of intake to the body in foodstuffs, to levels not exceeding one-tenth of the maximum permissible concentrations allowed in air, water, and foodstuffs for occupational exposure.
Page v - Each of these subcommittees is charged with the responsibility of preparing protection recommendations in its particular field. The reports of the subcommittees are approved by the main committee before publication. The following parent organizations and individuals comprise the main committee : American College of Radiology : RH Chamberlain and GC Henny.

Page 6 - The radiation or radioactive material outside a controlled area, attributable to normal operations within the controlled area, shall be such that it is improbable that any individual will receive a dose of more than 0.5 rem in any 1 year from external radiation.
