abstract = {Many people in Taiwan have been living in buildings
constructed with cobalt-60-contaminated steel rods. To study
the biological effects of chronic low-dose ionising
radiation on the residents of one such building,
micronucleus formation in these individuals was compared
with that in controls.The 73 residents had 77
age-and-sex-matched controls: 31 had 31 close relatives as
controls (group A controls); eight of the 31 had a second
set of close relatives; and the other controls were 38
residents in neighbouring buildings. Two micronucleus assays
were used-a cytochalasin B (CBMN) assay and another
involving incubation with cytarabine (CBMNA). Assay results
are given as "frequency", or the number of binucleate cells
containing one micronucleus per 1000 randomly examined
binucleate cells.The CBMN and CBMNA mean (SD) frequencies
for 31 exposed individuals (0.016 [0.009] and 0.025 [0.013]
respectively) were greater than those for their group A
controls (0.009 [0.004] and 0.016 [0.009], respectively) (p
= 0.0006 and 0.0002, respectively). The mean CBMN and CBMNA
frequencies for all the exposed individuals (0.017 [0.011]
and 0.030 [0.014], respectively) were significantly greater
than those for all controls (0.011 [0.008] and 0.019 [0.01];
p = 0.0001 for both comparisons). The ranges of the
differences in CBMN or CBMNA frequencies between 31 exposed
individuals and their group A controls were 0.003 to 0.020
and 0.001 to 0.032, respectively. After adjustment for age,
sex, and cigarette smoking, the adjusted relative risks of
micronucleus formation from radiation exposure in all 73
residents was 1.58 $(95\%$ CI 1.42-1.71; p = 0.0001) by the
CBMN assay and 1.64 (1.53-1.77; p = 0.0001) by the CBMNA
assay.These findings suggest that chronic low-dose and
low-dose-rate gamma-ray environmental exposure may induce
cytogenetic damage in human beings.},
