BNFL, British Nuclear Fuels; CI, confidence interval.

^{^a}

Values given are for deaths from ninth revision of International Classification of Diseases (ICD-9) codes 390–429.

^{^b}

Weighted sum of gamma and neutron doses to the colon among survivors with doses of ≥0.005 Sv.

^{^c}

Values given are for deaths from ICD-9 codes 410–414 during 1950–2003.

^{^d}

Not adjusted for smoking or alcohol.

^{^e}

Weighted sum of gamma and neutron shielded kerma doses. Doses to the Japanese A-bomb survivors arose predominantly from γ-radiation.

^{^f}

Adjusted for smoking and alcohol.

^{^g}

Dose to the lung.

^{^h}

Based on underlying cause of death. Results based on underlying and contributory causes combined are similar to these.

^ⁱ

Not cited in article.

^{^j}

Values given are for deaths from ICD-9 codes 414.0.

^{^k}

For males with adjustment for dose from internal alpha radiation.

^{^l}

Adjusted for sex, age, calendar year, duration of employment and social economic status, 90% CI.

^{^m}

Cumulative person-time-weighted lung dose.
