The 58th session of UNSCEAR took place at the Vienna International Centre, Vienna, Austria, from 23 to 27 May 2011. Wolfgang Weiss (Germany) was Chairman, Carl-Magnus Larsson (Australia) Vice-Chairman and Mohamed A. Gomaa (Egypt) Rapporteur for the session.

The Committee discussed matters arising from General Assembly resolution 65/96. It  also considered its future programme of work (including proposals on assessing the radiological impact of the the nuclear power plant accident following the great east-Japan earthquake and tsunami of March 2011, radiation effects on children, and epidemiology of low-dose rates of radiation exposure) and improving collection, analysis and dissemination of exposure data. The Committee held technical discussions on five documents prepared by the secretariat:

  • Ability to attribute risks and effects to radiation exposure
  • Uncertainties in risk estimates for cancer due to radiation exposure
  • Radiation exposures from electricity generation
  • Methodology for estimating human exposures due to discharges
  • Biological effects of selected internal emitters

57th session of UNSCEAR

The 57th session of UNSCEAR, originally scheduled to take place in 2009, was postponed from 2009 to 2010 owing to unforeseen circumstances. Owing to flight disruptions caused by ash from the volcanic eruption in Iceland, the session had to be postponed a second time from April to August 2010. It took place at the Vienna International Centre, Vienna, Austria from 16 to 20 August 2010. Norman Gentner (Canada) was Chairman, Wolfgang Weiss (Germany) Vice-Chairman and Mohamed A. Gomaa (Egypt) Rapporteur for the session.

  • Assessment of levels of radiation from electrical energy production
  • Uncertainty in radiation risk estimation
  • Attributability of health effects to radiation exposure
  • Methodology for estimating exposures due to discharges
  • Summary of radiation effects
  • Improving data collection, analysis and dissemination

The Committee has also elected officers for its fifty-eighth and fifty-ninth sessions.

56th session of UNSCEAR

The 56th session of UNSCEAR took place at the Vienna International Centre, Vienna, Austria from 10 to 18 July 2008. Norman Gentner (Canada) was Chairman, Wolfgang Weiss (Germany) was Vice-Chairman and Mohamed A. Gomaa (Egypt) was Rapporteur.

  • Medical radiation exposures
  • Exposures of workers and the public from various sources of radiation
  • Exposures from radiation accidents
  • Effects of ionizing radiation on non-human biota
  • Health effects due to radiation from the Chernobyl accident

The Committee approved a report to the 63rd General Assembly ( A/63/46), which describes the deliberations of the Committee at its fifty-sixth session, the strategic plan and programme of work, and a scientific report discussing sources of radiation exposure, the Chernobyl accident and effects on non-human biota.

The Committee also expressed its views on membership, staffing and financing, which were appended to a report of the Secretary-General on Financial and administrative implications of increased membership of the United Nations Scientific Committee on the Effects of Atomic Radiation, staffing of the professional secretariat of the Scientific Committee and methods to ensure sufficient, assured and predictable funding ( A/63/478).
