help in the preparation of future reports of the Committee to the General Assembly; and (b) encourage IAEA, WHO and other relevant organizations to collaborate with the Committee secretariat to establish and coordinate the arrangements for periodic collection and exchange of data on radiation exposures of the general public, workers and, in particular, medical patients.

of scientific developments and global communications, several strategic shifts initiated in 2008-2009 will continue, namely: (a) streamlining the Committee’s scientific evaluation processes; (b) enhancing mechanisms for data collection, analysis and dissemination; (c) improving results-based planning and coordination with other stakeholders; and (d) raising awareness of the Committee and its essential findings among decision makers and the public to help bridge the science-policy gap and identify any changes needed in the management of the impacts of radiation exposure on health and the environment.

development (adaptive response); (b) that the effects of radiation on the immune systems, which recognize and destroy abnormal cells, could influence the likelihood of cancer development; and (c) that radiation can produce changes that create long-lasting and transmissible effects on the stability of cellular DNA (genomic instability) and/or trigger the transfer of signals from damaged cells to their undamaged neighbours (bystander effects); both genomic instability and bystander effects have been suggested as possible factors that modify radiation-associated cancer risk.

considers that there is a threshold for these effects at about 100 mGy.

Intra-Oral Dental X-ray Sensors deliver a field-proven dental imaging solution based on fully-integrated CMOS photodiode arrays specifically designed for dental radiography.

continue at its next session the review of the important questions in the field of ionizing radiation and to report thereon to the Assembly at its sixty-fifth session; and resolved to take a decision on the membership of the Scientific Committee once a decision on resource allocation had been made and after the fifty-seventh session of the Scientific Committee but no later than the end of the sixty-fourth session of the General Assembly (resolution 64/85).
