From 8 to 10 February 2016, John D. Kinneman of AdSTM, Inc. participated in a five-member International Atomic Energy Agency (IAEA) team conducting an Advisory Mission to the country of Antigua and Barbuda. Antigua and Barbuda recently joined the IAEA and added a Cancer Center with significant radiation treatment facilities. The government has recognized the need for improving regulatory control of radiation sources to ensure the safety of workers, patients and the public. The recommendations of the Mission will lead to an action plan and improvements in regulation in the country.
