Unacceptable risks of thorium

Lynas issue: Not learning from bitter experience —The Malaysian Insider,  Richard Pendragon, April 12, 2012 “…..Unacceptable risks of thorium “No monetary returns of whatever Foreign Direct Investment and its spinoffs can outweigh possible radiation and/or other health risks,
which can wreak harm on our citizens, perhaps for as long as the half-lives of some of the extremely toxic radionuclide waste products —which in some cases might be ‘forever’!”

Dr David KL Quek, President, Malaysian Medical Association (MMA), May 26, 2011 One of the most contentious issues with the Lynas Advanced Materials Plant is the thorium (Th) by-product. Exposure to Thorium can cause cancer posing serious risks to workers at the LAMP and surrounding communities. Studies have shown that inhaling thorium dust causes an increased risk of developing lung cancer, and cancer of the pancreas. Bone cancer risk is also increased because thorium may be stored in bone. Thorium has a half life of 14 billion years and is easily transported and spread through wind and water.

Lynas will be processing 10 times the amount of ore compared to the ARE. Despite Lynas’ public proclamation of “Zero Harm” commitment there is no foolproof containment measures for such toxic residue for workers onsite at the LAMP. It should be noted that the ores that Chinese miners were exposed to in Bayun Obo Rare-Earth and Iron Mine
contained 400 ppm of thorium. The rare earth oxide concentrates that will be arriving shortly at Kuantan port will have 1600 ppm of thorium. The US Public Health Service (1990) reports that the natural background level in soil is typically 6 ppm of thorium.
