The 173 were hospitalized and later sent to the Da Lat Institute of Nuclear Research in central highlands Lam Dong Province for further examinations.
At 2:30 pm, experts from Alpha Company Limited which is being contracted to use radiographic equipment to check for cracks and welding deterioration at the Bunga Orkid D (BOD) oilrig off Ha Luu Port found a radioactive device missing. This bar-shaped device containing radioactive material is used to inspect the rig’s welding joints.
Immediately, over 400 people working within a radius of over 1km were evacuated. It was suspected that a group of technicians from Alpha had accidentally dropped the radioactive source at roughly 11:40 am about 20 meters away from the rig.
Since the device was dropped on the ground, it was easily located and retrieved after 3 hours.
The oilrig is owned by M&C Petroleum Technical Services Company.
Ho Minh Dan, Ba Ria Vung Tau provincial police chief told Sai Gon Giai Phong that there are no signs of sabotage.
Alpha had a similar problem at Hyundai-Vinashin Shipyard Ltd. in central Khanh Hoa province in 2002.
Viet Nam is upgrading security systems of its radioactive sources. The country currently houses 188 industrial and healthcare establishments having a total 1,961 radioactive sources.
Viet Nam which boasts a sole nuclear reactor in Lam Dong province plans to build its first nuclear power plant between 2015 and 2020.
