This publication comprises a report to the General Assembly with two underpinning scientific annexes. The first annex provides the principles and criteria for ensuring the quality of the Committee’s reviews of epidemiological studies of radiation exposures, with a focus on the assessment of strengths and limitations of such studies. The second annex evaluates epidemiological studies analysing cancer risk on the basis of individual doses due to exposure to low dose rates from environmental sources, including key limitations of such studies (e.g. statistical power, dosimetric uncertainty and confounding).
