IAEA/IAC releases study: “Assessment of Radiological Consequences and Evalaution of Measures for the Chernobyl Accident”
IAEA conclusions:
- there were no health disorders that could be directly attributed to radiation exposure. There were no indications of an increase in the incidence of leukaemia and cancers;
- there were significant non-radiation related health disorders in the populations of both the surveyed contaminated settlements and control settlements;
- the accident had substantial negative psychological consequences in terms of anxiety and stress due to continuing and high levels of uncertainty, relocation and other  measures;
- early evacuations undertaken by the authorities – in cases which could be assessed by the projects – were broadly reasonable and consistent with internationally-established guidelines
- protective measures taken or planned for the longer term, generally exceed what would have been strictly necessary
- official procedures for estimating doses were significantly sound
- etc

Main criticism on the report:
- study excluded from its subject of investigation the liquidators (estimated up to 600,000)
- study excluded the 30 km contaminated zone
- study excluded the evacuees from the zone (up to 95,000 – 100,000)
- study excluded hot spots
- There is some ambiguousness about the settlements chosen for the study: it would seem the selection was deliberate and arbitrary
- The report substantially underestimate the amount of exposure, particularly the lifetime dose. It appears that external exposure is estimated at one-third to one-fourth, and internal exposure at about one-tenth
- It is not clear how control groups were obtained. Thus, even though the study recognizes many illnesses and deaths, it was not able to link them to radiation (tot zover Tagaki, -medies, 21-5-91
- FoE claims that the IAEA scientists  are scientifically incompetent because they draw concrete conclusions on the basis of what they themselves admit are “not always adequate data”.
- The scientist had little or noaccess to pre-accident health records, leaving them unable to compare pre- and post-accident levels of disease and health disorders
- Etc.
According to Greenpeace the only aim of the study was to “produce a thirty-second sound-bite which is pleasing to the ear of the Soviet authorities – ‘we didn’t find radiation-induced health effects’ is constructed to avoid implicating radiation in the disaster
