The carcinogenic effects of exposure to ionizing radiation vary markedly with age, as revealed by studies of Japanese atomic bomb survivors and of Marshall Islanders exposed to fallout from U.S. nuclear weapons tests in the South Pacific in 1954. An increase in cancers of adulthood after intrauterine exposure, as reported in 1988, has not been sustained. After childhood exposure, increases in l...

BACKGROUND In all, 70 municipal incinerators, 307 hospital incinerators and 460 toxic-waste landfill sites in Great Britain were examined for evidence of effluents causing childhood cancers. Municipal incinerators had previously shown significant excesses of adult cancers within 7.5 and 3.0 km. The relative risks for adults had been marginal and an analysis of childhood cancers seemed to offer ...

STUDY OBJECTIVE The aim of the study was to examine a cohort of cases of childhood cancer occurring in a defined geographical area to try to identify clustering and possible causative factors. DESIGN Data were analysed using the close pair method developed by Knox for signs of clustering in relation to date and place of onset or date and place of birth. SETTING Cases were those occurring in...
