Exposed group: born from September 1950 to July 1954; unexposed group: born from September 1955 to August 1960
MR mortality ratio, NE not estimated due to small numbers
aHematopoietic cancer includes lymphoma, myeloma, and leukemia
bTotal mortality is for 1969–2003, but individual 5-year comparisons are only shown for 1983–2003 because of small numbers of deaths
