    A cohort mortality study of workers engaged in uranium milling and
    mining activities near Grants, New Mexico, during the period from
    1955 to 1990 was conducted. Vital status was determined through
    2005 and standardised mortality ratio (SMR) analyses were conducted
    for 2745 men and women alive after 1978 who were employed for at
    least six months. Overall, mortality from all causes (SMR 1.15; 95%
    CI 1.07-1.23; n = 818) and all cancers (SMR 1.22; 95% CI 1.07-1.38;
    n = 246) was greater than expected on the basis of US mortality
    rates. Increased mortality, however, was seen only among the 1735
    underground uranium miners and was due to malignant (SMR 2.17; 95%
    CI 1.75-2.65; n = 95) and non-malignant (SMR 1.64; 95% CI
    1.23-2.13; n = 55) respiratory diseases, cirrhosis of the liver
    (SMR 1.79; n = 18) and external causes (SMR 1.65; n = 58). The lung
    cancer excess likely is attributable to the historically high
    levels of radon in uranium mines of the Colorado Plateau, combined
    with the heavy use of tobacco products. No statistically
    significant elevation in any cause of death was seen among the 904
    non-miners employed at the Grants uranium mill. Among 718 mill
    workers with the greatest potential for exposure to uranium ore, no
    statistically significant increase in any cause of death of a
    priori interest was seen, i.e., cancers of the lung, kidney, liver,
    or bone, lymphoma, non-malignant respiratory disease, renal disease
    or liver disease. Although the population studied was relatively
    small, the follow-up was long (up to 50 yrs) and complete. In
    contrast to miners exposed to radon and radon decay products, for
    uranium mill workers exposed to uranium dusts and mill products
    there was no clear evidence of uranium-related disease.

nuclear power plants

    A recent study indicated an excess risk of leukaemia among children
    under the age of 5 years living in the vicinity of nuclear power
    plants in Germany. We present results relating to the incidence of
    childhood leukaemia in the vicinity of nuclear power plants in
    France for the same age range. These results do not indicate an
    excess risk of leukaemia in young children living near French
    nuclear power plants.
