“…I have found at Hiroshima that the cumulative death rate date curve is represented by the formula ( 1 )P (t) 1 -e-tk , where the only parameter a means the mean survival period [6] . It is the purpose of this paper to verify whether or not this law holds at Nagasaki and to compare two parameters a" and a, if the law holds.…”

This paper studies the mortality rate experienced by over 23,000 A-bomb survivors in Nagasaki between September 1945 and 1950 when the RERF-ABCC initiated the follow-up of the large LSS cohort. The study is based on the data of the 10-year House Reconstruction Survey. As expected, these data show an increasing mortality rate with increasing proximity to the hypocenter of the bomb. What was not anticipated was a higher mortality rate in the 1400-1699 m band than in the closer distance interval of 1200-1399 m. This suggests a possible selective survival among A-bomb survivors. Whether this affects the cancer risk estimates has not as yet been determined.

Data on a total of 7,593 persons in Hiroshima who were in 2,518 wooden Japanese houses and exposed to A-bomb within 1.6 km from the hypocenter have been used to estimate the LD50/60. The effect of radiation shielding for these people in particularly well-characterized in the new dosimetry system DS86. A range of values emerge, varying slightly with the method of estimation used. This range, derived from DS86 marrow doses, and based on a linear fit to equally weighted estimates of the probabilities of death at various doses, is 2.3-2.6 Gy. A linear estimate in which the probabilities of death at the various doses are weighted by the inverse of their variances is somewhat lower, 2.2 Gy. These values may be underestimates of actual LD50/60 because of inclusion of deaths in the first day, and the severely injured (burns, trauma) who survived the first day but succumbed later to their injuries.
