There has been heated debate over the radioactive waste produced at the Lynas Advanced Materials Plant (LAMP) in Kuantan, which is owned by Lynas Corporation, Ltd. an Australian rare-earths mining company. Lynas insists that it abides by international safety standards and industry practices, and that critics have ignored the science in the matter. Together with guest host and science journalist Dr. Law Yao Hua, we try to understand the science of radioactivity with the help of medical physicist Prof Ng Kwan Hoong from Universiti Malaya, and Dr Abdul Muin Abdul Rahman, the Deputy Director General of the Malaysian Nuclear Agency.
