Erratum to: Environ Health Prev Med (2008) 13:264–270 DOI 10.1007/s12199-008-0039-8

Our paper contained the following two errors. First, on pages 266 and 267, the phrase “person-years” should be “person” in the Table 1 and 2 footnotes “^a Observed number of deaths (person-years)” and “^b Expected number of deaths (person-years)”. Second, on page 267, the 95% confidential intervals (95% CI) for the SMR-O in the female very low dose category (<0.005 Sv) due to leukemia was “(0.469–1.945)” in the Table 2. However, we should have been listed as “(0.503–2.084)”. We regret any confusion these errors might have caused.
