About the Symposium

The fourth international conference in the series of Asia-Pacific Symposium on Radiochemistry (APSORC-09) will be held in Napa, California, U.S.A., from November 29 — December 4, 2009.

The first APSORC was held in Kumamoto, Japan (1997), the second in Fukuoka, Japan (2001), and the third in Beijing, China (2005). The conference provides an international forum for presentation and discussion of current and emerging sciences in all fields of radiochemistry and nuclear chemistry, and their applications to various fields. It aims to promote academic activities in nuclear, radiochemical and related sciences. Scientists, engineers and students from universities, institutes, laboratories and industries throughout the world are encouraged to participate and make contributions.
