Noorhasnah Khairullah, the special adviser to the AELB director-general, said the radiation at Bukit Merah had a natural origin.
"In some areas it is a bit high, such as at Pasir Hitam, Langkawi, it is 2.2 millisievert a year," she said at a public briefing at AELB headquarters today.
SMSL, which opposes the Lynas Advance Materials Plant operations in Gebeng, Kuantan, has claimed that radiation levels at the Mitsubishi Chemical's Asian Rare Earth (ARE) plant are still hazardous.
The group conducted tests at the grounds of the plant, which was closed down 18 years ago and claimed the radiation reading near the plant was around 0.19 microsievert per hour.
SMSL also claimed that the radiation reading near the ARE dumpsite was about 0.2 microsievert per hour, which would be beyond the safe 1 milisievert per year level.
AELB Licensing Division director Hasmadi Hassan, concurred with Noorhasnah's view, saying: "It depends on the geology of the location, pointing out that it was a tin mining area.
He added that what was under the ground would affect the radiation readings and noted that AELB had also gathered different readings throughout the Bukit Merah area.
The readings were all within the safety levels, he said.

Not a surprise. I've read article & reseach saying that Black Sand Beach has traces of some radioactive compound. But its not that high... This article confirms it..
