For public health safety, it is necessary to clarify pathways on how these radioactive elements reach human beings. Absorption and assimilation of radioactive elements by food crops are important ways to understand the hazardous of radiations for human health. Carbon-14 (14C, t1/2=5.73x103 yrs) from the radioactive waste is one of the most important radioactive nuclides for environmental assessment of the waste disposals. There are several kinds of organic compounds for ordinary portland cement of radioactive waste disposals such as acetic acid, formic acid, and formaldehyde. In the present study, we examined plant uptake and assimilation of carbon through plant roots by using 14C nuclide in the form of acetic acid., Eighth Conference of the East and Southeast Asia Federation of Soil Science}, title = {Absorption of 14C-Acetic Acid from Rice Rhizosphere}, year = {2007} }
