Fig. 1 Number of leukemia cases per year in the age group 5 to 14 in Utah. Also shown are the annual number of deaths due to nonmotor vehicle accidents for the same age-group as a reference. The population of Utah increased from 691,000 in 1950 to 901,000 in 1960, or by 30%. Note the 4 to 6 year delays between nuclear tests and rises of leukemia incidence.

Fig. 2 Number of deaths per year among congenitally defective children in Utah, age 0-4 yrs., 1937 to 1967. Also shown are deaths due to non-motor vehicle accidents for the same age group. Arrows indicate occurrence of nuclear tests with a 4 to 6 year delay.

Fig. 3 Number of deaths per year among congenitally defective children in Utah, age 5-14 yrs., 1937-1967. Also shown are non-motor vehicle accidents and leukemia for the same age group. Note particularly the large peak 5 years following the heavy St. George, Utah incident in 1953.

Fig. 4 Number of deaths per year among congenitally defective children in Missouri, age 5-14 yrs. Nevada tests took place until the temporary moratorium at the end of 1958.

Fig. 5 Number of deaths per year among congenitally defective children in Georgia, age 5-14 yrs.

Fig. 6 Number of deaths per year among congenitally defective children in Texas, age 5-14 yrs. Also shown are leukemia deaths for the same age group.

Fig. 7 Trends in rates of malignant tumors in Japan prior to and after the detonation of atomic weapons in 1945. Note particularly the rises in leukemia and cancer of the prostate, both of which were essentially constant prior to 1945.

Fig. 8 Cumulative excess number of leukemia deaths for 5-14 year old children in Utah relative to the 1949-54 rate of 3.8 +0.8 per year vs. cumulative thyroid dose from fresh fission products.

Fig. 9 Rates of deaths due to non-infectious respiratory diseases

in New York and New Mexico before and after the onset of nuclear testing in 1945. Note that the rates for New Mexico were below those in New York prior to 1946, after which the rates in New Mexico consistently exceeded those for heavily polluted New York.

Fig. 10 Mortality rate for malignant tumors of the bronchus, trachea and lung for U.S. white males, 75 to 84 years old before and after the onset of nuclear testing. Note the decline in the mortality rate between 1940 and 1948, followed by a sharp rise' in 1949, the same year that respiratory disease mortaliy rates in New York and Mexico from all other non-infectious causes (Fig. 9) rose sharply.
