More than 200,000 children in Belarus, Ukraine, and Russia affected by the Chernobyl disaster were examined for the health effects of radiation during 1991-2001. In early 1999, a satellite telemedicine system was set up, enabling exchanges of ultrasound thyroid images between Gomel Centre in Belarus and the Nagasaki University School of Medicine in Japan. It has helped to identify cases of thyroid cancer. Based on the success of this experience, SMHF launched a health telematics programme in Belarus in cooperation with WHO, which completed in 2004. SMHF has been also collaborating with EU, NCI (USA), WHO and 3 NIS governments to create a Chernobyl Tissue Bank. This will not only help the current sufferers for their diagnosis and treatment, but will also help us to know the health consequences, should similar accidents occur in the future.
