Description of RERF LSS-E85 Report 10 data file R10CANCR.DAT
The file R10CANCR.DAT on this disk contains data used in the
analyses of cancer mortality among survivors of the atomic bombings of
Hiroshima and Nagasaki. If these data are used as the basis for
analyses in any publication, including working papers and technical
reports, a statement of acknowledgement must be included in the
manuscript. This statement should read
This report makes use of data obtained from the Radiation Effects
Research Foundation (RERF), Hiroshima and Nagasaki, Japan. RERF
is a private, non-profit foundation funded by the Japanese Ministry
of Health, Labour and Welfare and the U.S. Department of Energy
the latter through the National Academy of Sciences. The conclusions
in this report are those of the authors and do not necessarily
reflect the scientific judgment of RERF or its funding agencies.

The data in the file summarize the cancer mortality experience
during the period from October 1, 1950 through December 31, 1982 for
91,231 exposed survivors in the Radiation Effects Research Foundation
Life Span Study cohort as extended in 1985 (LSS-E85). Data on
26,517 LSS members who were not in the city at the time of the bomb
(ATB) and 2,384 survivors for whom T65DR dose estimates could not be
caluclated have been excluded from the tabulation.
This dataset was used for most of the analyses described in LSS
Report 10 Part I. Cancer Mortality Among A-Bomb Survivors in Hiroshima
and Nagasaki, 1950-1982. This report, which has been published by RERF
as TR 1-86, contains a detailed description of the categories used to
classify deaths (Table A1-1), the method of person year calculation,
and the definition of the cross-classification used in the production
of this dataset. Data on specific categories of noncancer mortality are
not included in the file. Dose categories and estimates are based on
individual survivor T65DR dose estimates and do not reflect changes in
indivdual dose estimates due to recent substantial revisions in the
dosimetry system.
With the exception of some of the age-at-exposure by attained age
analyses, which made use of a slightly different tabulation, the
analyses described in the body and in Appendix 3 of LSS Report 10 were
based upon the data as summarized in R10CANCR.DAT.
R10CANCR.DAT is an ASCII text file. Each record in the line in the
file contains the data for a single cell in a crosstabulation over city
(2 groups), sex (2 groups), age ATB (5 groups), T65DR dose (8 groups),
and time period (8 groups). For each of these cells, the data are:
a) classmarks for city, sex, age ATB, dose, and time
b) an index variable which contains a unique value for each of the
160 strata defined by the city, sex, age ATB, and time period
categories.
c) the total number of person years at risk for persons in the cell
d) counts of the numbers of deaths in each of 26 nonexclusive
categories.
All fields are separated by at least one blank so the file can
easily be read using a FORTRAN free-format read. Alternatively, either
of the following FORTRAN formats can be used:
(2I3,I4,F7.1,I5,I4,F10.2,26I4)
or
(2F3.0,F4.0,F7.0,F5.0,F4.0,F10.0,26F4.0).
The following table describes the data for each record:
NAME Columns Description
__________ _________ ____________________________________________________
CITY 3 city indicator Hiroshima=0, Nagasaki=1
SEX 5 sex indicator Male=0, Female=1
AGEATB 9:10 age at exposure, value given is age at the midpoint of
the interval. There are 5 age at exposure intervals:
0-9,10-19,20-34,35-49,50+.
DOSE 11:17 T65DR total exposure kerma. The classmarks used are
city-specific dose group averages. The eight dose
groups are 0, 1-9, 10-49, 50-99, 100-199, 200-299,
300-399, and 400+ centigray(rad). T65DR exposure
kerma estimates were rounded to the neares t centigray
prior to grouping. In computing the city-specifc
averages, dose estimates in excess of 6 Gray were set
equal to 6 Gray. Average doses are given in
centiGray.
TIME 21:22 last two digits of the year at the midpoint of the
time interval. There are eight time intervals. The
first begins on October 1, 1950 and ends December 31,
1954. The remaining seven intervals are each four
years long. They begin on January 1 of 1955, 1959,
1963, 1967, 1971, 1975, and 1979. The final time
period ends on December 31, 1982.
INDEX 24:26 a variable which indexes strata defined by city, sex,
age ATB, and time period groups. There are 160 such
strata. The index values are integers between 1 and
160.
PYR 27:36 the total number of person years
ALLDEATH 37:40 all causes
ALLDIS 41:44 all diseases, including cancer
ALLNEO 45:48 all neoplasms
ALLMAL 49:52 all malignant neoplasms
LEUK 53:56 leukemia (acute and chronic)
NONLEUK 58:60 all cancers except leuklemia

organs
