Assessment Of Natural Radionuclides Activity And Heavy Metals Concentration In Paddy Plants And Their Influencing Factors In Penang, Malaysia
This research focus on the measurement of natural radioactivity and heavy metals in rice (Oryza sativa) and its surrounding media, which include agriculture soil and irrigation water. In order to determine the absorption of these metals by rice, the usage of fertilizers and the physico-chemical feat...
