Abstract of the paper:
This
paper discusses the results of the analysis of the relationship between
dose and solid cancer incidence among nuclear workers (males) who
worked as liquidators after the Chernobyl accident. Information on this
cohort of individuals is available at the regional center of Russian
National Medical and Dosimetric Registry operating at the RF State
Research Centre-Institute of Biophysics.
Medical and dosimetric
information on 8,654 persons 18-60 years of age with documented
external radiation doses is used for the analysis. These data were
gathered in the period from 1996 to 2001 and cover a total of 45,166.5
follow-up person-years. In the cohort under study, 179 solid cancers
occurred during this period.
The average age of liquidators at the time
of exposure was 35.8 years, and the average dose as a result of the
Chernobyl exposure was about 0.05 Sv. For an analysis of the
dose-effect relationship (induction of radiation-induced malignant
neoplasms) the statistical software EPICURE was used.
The results of
the analysis show that the cancer incidence in this cohort does not
exceed cancer incidence in relevant age groups of the Russian
population.
The mean value of SIR for all cancer diseases was 0.88
(0.76, 1.02, 95% CI) for the whole period of follow-up. Risks for the
induction of radiation-related cancer diseases were not statistically
meaningful. Excess relative risk per 1 Sv was 0.95 (-1.52, 4.49, 95%
CI).
