– A home-made neutron source built by 17-year-old David Hahn was discovered in his mother's back yard. The unshielded neutron source exposed his neighborhood to 1,000 times the normal levels of background radiation. October 21, 1994 – Theft of radioactive material in Tammiku: a strong caesium-137 source was stolen by scrap metal scavengers in Tammiku, Männiku, Saku Parish, Estonia. The man who carried the source home received a 4,000 rad whole-body dose and died 12 days after first taking it. In addition, the man's stepson sustained radiation burn injuries to his hands after he found and touched the source after the man had placed it inside a kitchen drawer. September, 1996 – San José, Costa Rica: A cobalt radiation therapy device was not properly tuned and 116 patients that were undergoing treatment were irradiated with a very high dose. May 1998 – Acerinox accident – recycler Acerinox in Cádiz, Spain, unwittingly melted scrap metal containing radioactive sources; the radioactive cloud drifted to Switzerland before being detected. December 1998 – Istanbul, Turkey – two sealed transport packages for spent 60Co teletherapy sources from a shipment of three planned for export in 1993 were instead stored in a warehouse in Ankara, then moved to Istanbul, where a new owner sold them off as scrap metal. The buyers dismantled the containers, exposing themselves and others to ionizing radiation. Eighteen people, including seven children, were admitted to hospital. Ten of the adults developed acute radiation syndrome. One exposed 60Co source was retrieved, but the source from the other package was still unaccounted for one year later. It is believed that the second container was empty all along, but this could not be conclusively proven from company records. 1999 – A road near Mrima Hill, Kenya was rebuilt using local materials later found to be radioactive. Some workers were exposed to excessive radiation, and many residents of the area were tested for exposure. 2,975 t of roadway material were to be dug up to eliminate the hazard. 1999 - Yanango, Peru: A construction worker and his family were exposed to an Ir-192 industrial radiography source after the worker picked-up the source and carried it in his back pocket for 17 hours. The exposure received to his whole body was estimated to be approximately 150 Rem, and exposure to his right buttocks was 10,000 Rad. 2000s February 1, 2000 – Samut Prakan radiation accident: The radiation
