This report summarized activities of the TENORM task group of the FNCA held in Thailand during August 23-27, 2004. TENORM inventory, regulations and laws, and the country specific problems are also included in this report. Groups of industries lead to enhanced occupational and public exposure to TENORM in Thailand included oil and gas exploration and production, metal production i. e. tantalum, niobium, tin, and rare earths, cement production, steel refinery, water treatment, coal and coal power production, chemical fertilizer, and residues from past activities with various range of capacity. Waste volume generated and TENORM activity concentrations in waste were estimated based on information from various reports and data. TENORM waste volume generated was estimated 150, 000 ty-with activity concentration ranges from 0. 14-1. 3 Bqg-1 of 226Ra. Thailand has no regulation directly control of NORM and TENORM. However, article 2 of the Thai Ministerial Regulation No. 5 BE. 2516 (1973) clarified: any materials that contained uranium oxide (U308) or thorium oxide (Th02)/ or uranium oxide and thorium oxide at concentrated level more than 15% of the original ore element will be accounted as radioactive source materials. Practical guidance based on BSS No. 115 must be applied on all activities dealing with those materials. The specific problems of the country for controlling TENORM are the lack of: understanding on TENORM sources, information on location and extent of existing TENORM sites, safely and economically guidance on controlling exposure to TENORM, information distribution and cooperation network, and a suitable and correct method on sampling and measurement of TENORM.

Regional cooperation in radioactive waste management (RWM) in the Asian and Oceanic countries has been successfully developing for more than 20 y. At present, the Asian and Oceanic countries recognise that there are several projects under the regional cooperation, such as the Forum for Nuclear Cooperation in Asia (FNCA), the Asian Nuclear Safety Network (ANSN) and the International Atomic Energy Agency (IAEA) regional projects. The FNCA on Radiation Safety and RWM is an effective mechanism for enhancing socio-economic development through active regional partnership in the peaceful and safe utilisation of nuclear technology. The ANSN Topical Group on RWM is established for exchanging, pooling, and sharing knowledge in the field of nuclear safety. For IAEA regional cooperation on RWM, such as IAEA-regional project RAS/3/009 Strengthening Infrastructure of RWM can provide and support Asian and Oceanic countries for national work plan, fellowships and scientific visits as well as expert services.
