Changes of phosphorus, 210Po and 210Pb in water column at Mersing River, Johor
The studies on natural radionuclides such as 210Po and 210Pb with the concentration of phosphorus in water column were carried out in Mersing River, Johor. There were 16 water samples were collected from nine stations during Mersing Expedition 2010 on the 4th July 2010. The samples were treated by u...
