Indonesia names a Chinese metal company executive as a suspect in contaminated radioactive material case

Indonesian authorities named the director of a scrap-metal company on Thursday as a suspect. They accused the firm of breaking environmental laws regarding storage and disposal. A local company, also located in the Modern Cikande Industrial Estate in Jakarta, detected the caesium-137 contamination in shrimps shipped to the United States by a local firm in August. Indonesia then began conducting sweeping scans in that area.

Indonesia's Government has said that PT Peter Metal Technology, a factory owned and operated by foreign investors which ceased operation in July was the epicenter of radioactive contamination.

Police said that PT PMT director Lin Jingzhang is a Chinese citizen and a suspect of spreading contamination. Lin is not charged, and is helping with the investigation. However, he is prohibited from leaving Indonesia.

Sardo Sbarani, an investigator with the Criminal Investigation Agency of the National Police, said: "He wasn't detained, because we saw that he was cooperative."

Lin could not be reached for comment, and PT PMT didn't respond immediately to messages sent to a mobile number listed in Indonesia's company registry.

Caesium 137 is released into the environment by past nuclear accidents or tests, such as Chernobyl. It's also used for industrial purposes like oil well logging. Indonesia does not have nuclear weapons or power plants.

The task force that investigated the contamination stated that all scrap metal produced by PT PMT came from domestic sources, while stainless steel was exported by PT PMT to China. Investigators suspect that hazardous and toxic waste discovered at a scrapyard in the estate was produced by PT PMT. The company set up on the estate two year ago, and operated a facility to manufacture and grind non-ferrous metals.

Bara Hasibuan said that the purchase of scrap material mixed with used industrial equipment contained Caesium-137. The materials were processed either legally or illegally, without proper storage, supervision, and disposal in accordance with applicable laws.
