Radioactive Fallout

Archives of Environmental Health: An International Journal, 1963
THE DETONATION of nuclear devices produces fission products in greater or lesser amounts, depending on the characteristics of the particular device employed. Fission devices which are in the low-yield range derive their explosive force from nuclear fission which gives rise to amounts of radioactive fission products roughly proportional to explosive ...

Radioactive Fallout and Radioactive Strontium

Science, 1956
The contribution to environmental radioactivity of radioactivity due to fallout following the explosion of nuclear weapons is reviewed. Mechanisms by which /sup 90/Sr might be expected to enter the human body are discussed in detail. Data from nuclear weapons tests form the basis for the conclusion that the main part of the radioactivity from high ...

Radioactive Fallout in the United States

Science, 1955
Fallout in the United States from early in 1951 through 1954 is summarized. Accumulated fission product activity in the United States, exclusive of the area within 200 miles of the Nevada test site, was 61 millicuries per square mile. Gamma radiation from this is of the order of 0.0010 mr/hr compared with normal background of 0.005 to 0.05 mr/hr.

Radioactive Fallout During 1959

Nature, 1960
ABS>The concentration of strontium-90 In rain falling over Great Britain rose sharply during the first half of 1959 despite the suspension of nuclear weapons testing from November 1955 until February 1960 Results are presented from measurements of the radiostrontium content of rain water sampled through 1959.

The Inhalation Hazard of Radioactive Fallout

Health Physics, 1988
The inhalation hazard of fallout particles from a nuclear ground burst has been evaluated with the ICRP Task Group Lung Model and the DELFIC fallout model for the 0.5-kt to 10-Mt yield range. It was found that for the conditions considered in this work, the inhalation of fallout particles does not present a significant radiological hazard.

Hazards of Radioactive Fallout

Pediatrics, 1963
The Committee on Environmental Hazards, in its efforts to acquaint members of the Academy with the real hazards of radioactive fallout, has been encouraged by actions of important groups and individuals qualified in that field. For example, the USPHS, charged with the responsibility of the welfare of our population, has requested and received copies of

Radioactive fallout and cancer.

JAMA, 1984
To the Editor.— The study by Dr Carl Johnson 1 quoted our work out of context 2 to support the accuracy of his method of identifying cancer cases among those exposed to radioactive fallout. Johnson used community volunteers to interview self-selected heads of families to ascertain each cancer in family members over the preceding 30 years.

Hazards of Radioactive Fallout

Pediatrics, 1962
Very properly, the American Academy of Pediatrics has appointed a Committee on Environmental Hazards to consider the "problems posed for pediatricians by fallout of radioactive materials in this country." We in practice had looked forward to the reports of this Committee because the pediatric literature had been singularly free of relevant material ...
